DSP56311

24-Bit Digital Signal Processor

The Freescale DSP56311, a member of the DSP56300 DSP family, supports network applications with general filtering operations. The Enhanced Filter Coprocessor (EFCOP) executes filter algorithms in parallel with core operations enhancing signal quality with no impact on channel throughput or total channels supported. The result is increased overall performance. Like the other DSP56300 family members, the DSP56311 uses a high-performance, single-clock-cycle-per- instruction engine (DSP56000 code-compatible), a barrel shifter, 24-bit addressing, an instruction cache, and a direct memory access (DMA) controller (see Figure 1). The DSP56311 performs at up to 150 million multiply-accumulates per second (MMACS), attaining up to 300 MMACS when the EFCOP is in use. It operates with an internal 150 MHz clock with a 1.8 volt core and independent 3.3 volt input/output (I/O) power.

The DSP56311 input and output signals are organized into functional groups as shown in Tab l e 1- 1 . Figure 1-1 diagrams the DSP56311 signals by functional group. The remainder of this chapter describes the signal pins in each functional group.

Note:

The Clock Output (CLKOUT), BCLK, BCLK, CAS, and RAS[0–3] signals used by other DSP56300 family members are supported by the DSP56311 at operating frequencies up to 100 MHz. Therefore, above 100 MHz, you must enable bus arbitration by setting the Asynchronous Bus Arbitration Enable Bit (ABE) in the operating mode register. When set, the ABE bit eliminates the required set-up and hold times for

BB and BG with respect to CLKOUT. In

addition, DRAM access is not supported above 100 MHz.

Notes: 1. The HI08 port supports a non-multiplexed or a multiplexed bus, single or double Data Strobe (DS), and single or

double Host Request (HR) configurations. Since each of these modes is configured independently, any combination of these modes is possible. These HI08 signals can also be configured alternatively as GPIO signals (PB[0–15]). Signals with dual designations (for example, HAS

/HAS) have configurable polarity.

2. The ESSI0, ESSI1, and SCI signals are multiplexed with the Port C GPIO signals (PC[0–5]), Port D GPIO signals (PD[0–5]), and Port E GPIO signals (PE[0–2]), respectively.

3. TIO[0–2] can be configured as GPIO signals.

Signal Description

CLKOUT Output Chip-driven Clock Output—Provides an output clock synchronized to the internal core

clock phase.

If the PLL is enabled and both the multiplication and division factors equal one, then CLKOUT is also synchronized to EXTAL.

If the PLL is disabled, the CLKOUT frequency is half the frequency of EXTAL.

Note: At oper ating frequencies above 100 MHz, this signal produces a lowamplitude waveform that is not usable externally by other devices. Above 100 MHz, you can use the asynchronous bus arbitration option that is enabled by the Asynchronous Bus Arbitration Enable (ABE) bit in the Operating Mode Register. When set, the DSP enters the Asynchronous Arbitration mode, which eliminates the BB

and BG set-up and hold time requirements with

respect to CLKOUT.

PCAP Input Input PLL Capacitor—An input connecting an off-chip capacitor to the PLL filter.

Connect one capacitor terminal to PCAP and the other terminal to V

CCP

If the PLL is not used, PCAP can be tied to V

, GND, or left floating.

PINIT

Input PLL Initial—During assertion of RESET, the value of PINIT is written into the

PLL enable (PEN) bit of the PLL control (PCTL) register, determining whether the PLL is enabled or disabled.

Nonmaskable Interrupt—After RESET

deassertion and during normal instruction processing, this Schmitt-trigger input is the negative-edge-triggered NMI request internally synchronized to CLKOUT.

Signal Description

AA[0–3]

RAS[0–3]

Output

Tri-stated Address Attribute—When defined as AA, these signals can be used as chip selects

or additional address lines. The default use defines a priority scheme under which only one AA signal can be asserted at a time. Setting the AA priority disable (APD) bit (Bit 14) of the Operating Mode Register, the priority mechanism is disabled and the lines can be used together as four external lines that can be decoded externally into 16 chip select signals.

Row Address Strobe—When defined as RAS

, these signals can be used as RAS for

DRAM interface. These signals are tri-statable outputs with programmable polarity.

Note: DRAM access is not supported above 100 MHz.

Output Tri-stated Read Enable—When the DSP is the bus master, RD is an active-low output that is

asserted to read external memory on the data bus (D[0–23]). Otherwise, RD

is tri-

stated.

Output Tri-stated Write Enable—When the DSP is the bus master, WR is an active-low output that is

asserted to write external memory on the data bus (D[0–23]). Otherwise, the signals are tri-stated.

Input Ignored Input Transfer Acknowledge—If the DSP56311 is the bus master and there is no external

bus activity, or the DSP56311 is not the bus master, the TA

input is ignored. The TA input is a data transfer acknowledge (DTACK) function that can extend an external bus cycle indefinitely. Any number of wait states (1, 2. . .infinity) can be added to the wait states inserted by the bus control register (BCR) by keeping TA

deasserted. In

typical operation, TA

is deasserted at the start of a bus cycle, asserted to enable completion of the bus cycle, and deasserted before the next bus cycle. The current bus cycle completes one clock period after TA

is deasserted. The number of wait

states is determined by the TA

input or by the BCR, whichever is longer. The BCR sets the minimum number of wait states in external bus cycles. In order to use the TA functionality, the BCR must be programmed to at least one wait state. A zero wait state access cannot be extended by TA

deassertion.

At operating frequencies ≤ 100 MHz, TA

can operate synchronously (with respect to CLKOUT) or asynchronously depending on the setting of the TAS bit in the Operating Mode Register (OMR). If synchronous mode is selected, the user is responsible for ensuring that TA

transitions occur synchronous to CLKOUT to ensure correct operation. Synchronous operation is not supported above 100 MHz and the OMR[TAS] bit must be set to synchronize the TA

signal with the internal clock.

DSP56311 Technical Data, Rev. 8

Signals/Connections

BR Output Reset: Output

(deasserted)

State during Stop/Wait depends on BRH bit setting:

• BRH = 0: Output, deasserted

• BRH = 1: Maintains last state (that is, if asserted, remains asserted)

Bus Request—Asserted when the DSP requests bus mastership. BR

is deasserted

when the DSP no longer needs the bus. BR

may be asserted or deasserted independently of whether the DSP56311 is a bus master or a bus slave. Bus “parking” allows BR

to be deasserted even though the DSP56311 is the bus master.

(See the description of bus “parking” in the BB

signal description.) The bus request

hold (BRH) bit in the BCR allows BR

to be asserted under software control even

though the DSP does not need the bus. BR

is typically sent to an external bus arbitrator that controls the priority, parking, and tenure of each master on the same external bus. BR

is affected only by DSP requests for the external bus, never for the

internal bus. During hardware reset, BR

is deasserted and the arbitration is reset to

the bus slave state.

Input Ignored Input Bus Grant—Asserted by an external bus arbitration circuit when the DSP56311

becomes the next bus master. When BG

is asserted, the DSP56311 must wait until

is deasserted before taking bus mastership. When BG is deasserted, bus mastership is typically given up at the end of the current bus cycle. This may occur in the middle of an instruction that requires more than one external bus cycle for execution.

The default operation of this bit requires a set-up and hold time as specified in Chapter 2. An alternate mode can be invoked: set the asynchronous bus arbitration enable (ABE) bit (Bit 13) in the Operating Mode Register. When this bit is set, BG

and

are synchronized internally. This eliminates the respective set-up and hold time requirements but adds a required delay between the deassertion of an initial BG

input

and the assertion of a subsequent BG

input.

Input/ Output Ignored Input Bus Busy—Indicates that the bus is active. Only after BB is deasserted can the

pending bus master become the bus master (and then assert the signal again). The bus master may keep BB

asserted after ceasing bus activity regardless of whether

is asserted or deasserted. Called “bus parking,” this allows the current bus master to reuse the bus without rearbitration until another device requires the bus. BB

deasserted by an “active pull-up” method (that is, BB

is driven high and then released

and held high by an external pull-up resistor).

The default operation of this signal requires a set-up and hold time as specified in Chapter 2. An alternative mode can be invoked by setting the ABE bit (Bit 13) in the Operating Mode Register. When this bit is set, BG

and BB are synchronized

internally. See BG

for additional information.

Note: BB

requires an external pull-up resistor.

CAS

Output Tri-stated Column Address Strobe—When the DSP is the bus master, CAS is an active-low

output used by DRAM to strobe the column address. Otherwise, if the Bus Mastership Enable (BME) bit in the DRAM control register is cleared, the signal is tristated.

Note: DRAM access is not supported above 100 MHz.

BCLK Output Tri-stated Bus Clock

When the DSP is the bus master, BCLK is active when the ATE bit in the Operating Mode Register is set. When BCLK is active and synchronized to CLKOUT by the internal PLL, BCLK precedes CLKOUT by one-fourth of a clock cycle.

Note: At operating frequencies above 100 MHz, this signal produces a low-amplitude waveform that is not usable externally by other devices.

BCLK

Output Tri-stated Bus Clock Not

When the DSP is the bus master, BCLK

is the inverse of the BCLK signal. Otherwise,

the signal is tri-stated.

Note: At operating frequencies above 100 MHz, this signal produces a low-amplitude waveform that is not usable externally by other devices.

1.7 Host Interface (HI08)

The HI08 provides a fast, 8-bit, parallel data port that connects directly to the host bus. The HI08 supports a variety of standard buses and connects directly to a number of industry-standard microcomputers, microprocessors, DSPs, and DMA hardware.

1.7.1 Host Port Usage Considerations

Careful synchronization is required when the system reads multiple-bit registers that are written by another asynchronous system. This is a common problem when two asynchronous systems are connected (as they are in the Host port). The considerations for proper operation are discussed in Table 1-10.

1.7.2 Host Port Configuration

HI08 signal functions vary according to the programmed configuration of the interface as determined by the 16 bits in the HI08 Port Control Register.

Table 1-10. Host Port Usage Considerations

Action Description

Asynchronous read of receive byte registers

When reading the receive byte registers, Receive register High (RXH), Receive register Middle (RXM), or Receive register Low (RXL), the host interface programmer should use interrupts or poll the Receive register Data Full (RXDF) flag that indicates data is available. This assures that the data in the receive byte registers is valid.

Asynchronous write to transmit byte registers

The host interface programmer should not write to the transmit byte registers, Transmit register High (TXH), Transmit register Middle (TXM), or Transmit register Low (TXL), unless the Transmit register Data Empty (TXDE) bit is set indicating that the transmit byte registers are empty. This guarantees that the transmit byte registers transfer valid data to the Host Receive (HRX) register.

Asynchronous write to host vector The host interface programmer must change the Host Vector (HV) register only when the Host

Command bit (HC) is clear. This practice guarantees that the DSP interrupt control logic receives a stable vector.

Input/ Output Input Debug Event—As an input, initiates Debug mode from an external command

controller, and, as an open-drain output, acknowledges that the chip has entered Debug mode. As an input, DE

causes the DSP56300 core to finish executing the current instruction, save the instruction pipeline information, enter Debug mode, and wait for commands to be entered from the debug serial input line. This signal is asserted as an output for three clock cycles when the chip enters Debug mode as a result of a debug request or as a result of meeting a breakpoint condition. The DE

has an internal pull-up resistor.

This signal is not a standard part of the JTAG TAP controller. The signal connects directly to the OnCE module to initiate debug mode directly or to provide a direct external indication that the chip has entered Debug mode. All other interface with the OnCE module must occur through the JTAG port.

The DSP56311 is fabricated in high-density CMOS with transistor-transistor logic (TTL) compatible inputs and outputs.

2.1 Maximum Ratings

In the calculation of timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction. Therefore, a “maximum” value for a specification never occurs in the same device that has a “minimum” value for another specification; adding a maximum to a minimum represents a condition that can never exist.

CAUTION

This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. Reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or V

2. Section 4.3 provides a formula to compute the estimated current requirements in Normal mode. To obtain these results, all inputs must be terminated (that is, not allowed to float). Measurements are based on synthetic intensive DSP benchmarks (see

Appendix A

). The power consumption numbers in this specification are 90 percent of the measured results of this benchmark.

This reflects typical DSP applications. Typical internal supply current is measured with V

3. To obtain these results, all inputs must be terminated (that is, not allowed to float). PLL and XTAL signals are disabled during Stop state.

4. DC current in Stop mode is evaluated based on measurements. To obtain these results, all inputs not disconnected at Stop mode must be terminated (that is, not allowed to float).

2.4 AC Electrical Characteristics

The timing waveforms shown in the AC electrical characteristics section are tested with a VIL maximum of 0.3 V and a V

minimum of 2.4 V for all pins except EXTAL, which is tested using the input levels shown in Note 6 of

Tab l e 2- 2. AC timing specifications, which are referenced to a device input signal, are measured in production with respect to the 50 percent point of the respective input signal’s transition. DSP56311 output levels are measured with the production test machine V

and VOH reference levels set at 0.4 V and 2.4 V, respectively.

Note: Although the minimum value for the frequency of EXTAL is 0 MHz, the device AC test conditions are 15

MHz and rated speed.

2.4.2 External Clock Operation

The DSP56311 system clock is derived from the on-chip oscillator or is externally supplied. To use the on-chip oscillator, connect a crystal and associated resistor/capacitor components to EXTAL and XTAL; examples are shown in Figure 2-1.

If an externally-supplied square wave voltage source is used, disable the internal oscillator circuit during bootup by setting XTLD (PCTL Register bit 16 = 1—see the DSP56311 User’s Manual). The external square wave source connects to EXTAL; XTAL is not physically connected to the board or socket. Figure 2-2 shows the relationship between the

EXTAL input and the internal clock and CLKOUT.

Notes: 1. When fast interrupts are used and IRQA

, IRQB, IRQC, and IRQD are defined as level-sensitive, timings 19 through 21 apply to prevent multiple interrupt service. To avoid these timing restrictions, the deasserted Edge-triggered mode is recommended when fast interrupts are used. Long interrupts are recommended for Level-sensitive mode.

2. This timing depends on several settings:

• For PLL disable, using internal oscillator (PLL Control Register (PCTL) Bit 16 = 0) and oscillator disabled during Stop (PCTL Bit 17 = 0), a stabilization delay is required to assure that the oscillator is stable before programs are executed. Resetting the Stop delay (Operating Mode Register Bit 6 = 0) provides the proper delay. While Operating Mode Register Bit 6 = 1 can be set, it is not recommended, and these specifications do not guarantee timings for that case.

• For PLL disable, using internal oscillator (PCTL Bit 16 = 0) and oscillator enabled during Stop (PCTL Bit 17=1), no stabilization delay is required and recovery is minimal (Operating Mode Register Bit 6 setting is ignored).

• For PLL disable, using external clock (PCTL Bit 16 = 1), no stabilization delay is required and recovery time is defined by the PCTL Bit 17 and Operating Mode Register Bit 6 settings.

• For PLL enable, if PCTL Bit 17 is 0, the PLL is shutdown during Stop. Recovering from Stop requires the PLL to get locked. The PLL lock procedure duration, PLL Lock Cycles (PLC), may be in the range of 0 to 1000 cycles. This procedure occurs in parallel with the stop delay counter, and stop recovery ends when the last of these two events occurs. The stop delay counter completes count or PLL lock procedure completion.

• PLC value for PLL disable is 0.

• The maximum value for ET

is 4096 (maximum MF) divided by the desired internal frequency (that is, for 66 MHz it is 4096/66

MHz = 62 µs). During the stabilization period, T

, TH, and TL is not constant, and their width may vary, so timing may vary as

well.

3. Periodically sampled and not 100 percent tested.

4. Value depends on clock source:

• For an external clock generator, RESET

duration is measured while RESET is asserted, VCC is valid, and the EXTAL input is

active and valid.

• For an internal oscillator, RESET

duration is measured while RESET is asserted and V

is valid. The specified timing reflects the crystal oscillator stabilization time after power-up. This number is affected both by the specifications of the crystal and other components connected to the oscillator and reflects worst case conditions.

• When the V

is valid, but the other “required RESET duration” conditions (as specified above) have not been yet met, the device circuitry is in an uninitialized state that can result in significant power consumption and heat-up. Designs should minimize this state to the shortest possible duration.

2.4.5.2 DRAM Timing

The selection guides in Figure 2-12 and Figure 2-15 are for primary selection only. Final selection should be based on the timing in the following tables. For example, the selection guide suggests that four wait states must be used for 100 MHz operation with Page Mode DRAM. However, consulting the appropriate table, a designer can evaluate whether fewer wait states might suffice by determining which timing prevents operation at 100 MHz, running the chip at a slightly lower frequency (for example, 95 MHz), using faster DRAM (if it becomes available), and manipulating control factors such as capacitive and resistive load to improve overall system performance.

2.4.5.3 Asynchronous Bus Arbitration Timings

The asynchronous bus arbitration is enabled by internal synchronization circuits on BG and BB inputs. These synchronization circuits add delay from the external signal until it is exposed to internal logic. As a result of this delay, a DSP56300 part may assume mastership and assert

BB, for some time after BG is deasserted. This is the

reason for timing 250.

Once

BB is asserted, there is a synchronization delay from BB assertion to the time this assertion is exposed to other

DSP56300 components that are potential masters on the same bus. If

BG input is asserted before that time, and BG

is asserted and

BB is deasserted, another DSP56300 component may assume mastership at the same time.

Therefore, some non-overlap period between one

BG input active to another BG input active is required. Timing 251

ensures that overlaps are avoided.

Notes: 1. Bit 13 in the Operating Mode Register must be set to enable Asynchronous Arbitration mode.

2. At 150 MHz, Asynchronous Arbitration mode is recommended.

3. To guarantee timings 250 and 251, it is recommended that you assert non-overlapping BG

inputs to different DSP56300

devices (on the same bus), as shown in Figure 2-19, where BG1

is the BG signal for one DSP56300 device while BG2 is the

signal for a second DSP56300 device.

DSP56311 User’s Manual

2. In the timing diagrams below, the controls pins are drawn as active low. The pin polarity is programmable.

3. This timing is applicable only if two consecutive reads from one of these registers are executed.

4. The data strobe is Host Read (HRD) or Host Write (HWR) in the Dual Data Strobe mode and Host Data Strobe (HDS) in the

Single Data Strobe mode.

5. The read data strobe is HRD in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.

6. The write data strobe is HWR in the Dual Data Strobe mode and HDS in the Single Data Strobe mode.

7. The host request is HREQ in the Single Host Request mode and HRRQ and HTRQ in the Double Host Request mode.

8. The “Last Data Register” is the register at address $7, which is the last location to be read or written in data transfers. This is

RXL/TXL in the Big Endian mode (HLEND = 0; HLEND is the Interface Control Register bit 7—ICR[7]), or RXH/TXH in the Little Endian mode (HLEND = 1).

9. In this calculation, the host request signal is pulled up by a 4.7 kΩ resistor in the Open-drain mode.

10. V

CCQH

= 3.3 V ± 0.3 V, V

= 1.8 V ± 0.1 V; TJ = –40°C to +100 °C, CL = 50 pF

11. This timing is applicable only if a read from the “Last Data Register” is followed by a read from the RXL, RXM, or RXH registers without first polling RXDF or HREQ bits, or waiting for the assertion of the HREQ signal.

12. After the external host writes a new value to the ICR, the HI08 is ready for operation after three DSP clock cycles (3 × Tc).

Notes: 1. For the internal clock, the external clock cycle is defined by the instruction cycle time (timing 7 in Ta ble 2 -5 on page 2-6) and

the ESSI Control Register.

2. The word-length-relative frame sync signal waveform operates the same way as the bit-length frame sync signal waveform, but spreads from one serial clock before the first bit clock (same as the Bit Length Frame Sync signal) until the one before last bit clock of the first word in the frame.

2.4.10.2 With an Operating Frequency above 100 MHz

The following considerations can be helpful when GPIO is used for output or input with an operating frequency above 100 MHz (that is, when

CLKOUT is not available).

• GPIO as Output:

— The time from fetch of the instruction that changes the GPIO pin to the actual change is seven core

clock cycles. This is true, assuming that the instruction is a on

e-cycle instruction and that there are no

pipeline stalls or any other pipeline delays.

— The maximum rise or fall time of a GPIO pin is 13 ns (TTL levels, assuming that the maximum of 50

pF load limit is met).

• GPIO as Input—GPIO inputs are not synchronized with the core clock. When only one GPIO bit is polled, this lack of synchronization presents no problem, since the read value can be either the previous value or the new value of the corresponding GPIO pin. However, there is the risk of reading an intermediate state if:

— Two or more GPIO bits are treated as a coupled group (for example, four possible status states encoded

in two bits).

— The read operation occurs during a simultaneous change of GPIO pins (for example, the change of 00

to 11 may happen through an intermediate state of 01 or 10).

Therefore, when GPIO bits are read, the recommended practice is to poll continuously until two consecutive read operations have identical results.

Notes: 1. Signal names are based on configured functionality. Most connections supply a single signal. Some connections provide a

signal with dual functionality, such as the MODx/IRQx

pins that select an operating mode after RESET is deasserted but act as interrupt lines during operation. Some signals have configurable polarity; these names are shown with and without overbars, such as HAS

/HAS. Some connections have two or more configurable functions; names assigned to these connections indicate the function for a specific configuration. For example, connection N2 is data line H7 in non-multiplexed bus mode, data/address line HAD7 in multiplexed bus mode, or GPIO line PB7 when the GPIO function is enabled for this pin. Unlike in the TQFP package, most of the GND pins are connected internally in the center of the connection array and act as heat sink for the chip. Therefore, except for GND

and GNDP1 that support the PLL, other GND signals do not support individual

subsystems in the chip.

2. CLKOUT, BCLK

, and BCLK are available only if the operating frequency is ≤ 100 MHz.

Design Considerations 4

This section describes various areas to consider when incorporating the DSP56311 device into a system design.

4.1 Thermal Design Considerations

An estimate of the chip junction temperature, TJ, in ° C can be obtained from this equation:

Equation 1:

Where:

= ambient temperature °C

θJA

= package junction-to-ambient thermal resistance °C/W

PD = power dissipation in package

Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a caseto-ambient thermal resistance, as in this equation:

Equation 2:

Where:

θJA

= package junction-to-ambient thermal resistance °C/W

θJC

= package junction-to-case thermal resistance °C/W

θCA

= package case-to-ambient thermal resistance °C/W

θJC

is device-related and cannot be influenced by the user. The user controls the thermal environment to change

the case-to-ambient thermal resistance, R

θCA

. For example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the printed circuit board (PCB) or otherwise change the thermal dissipation capability of the area surrounding the device on a PCB. This model is most useful for ceramic packages with heat sinks; some 90 percent of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. For ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the PCB, analysis of the device thermal performance may need the additional modeling capability of a system-level thermal simulation tool.

The thermal performance of plastic packages is more dependent on the temperature of the PCB to which the package is mounted. Again, if the estimates obtained from R

θJA

do not satisfactorily answer whether the thermal

performance is adequate, a system-level model may be appropriate.

A complicating factor is the existence of three common ways to determine the junction-to-case thermal resistance in plastic packages.

Design Considerations

• To minimize temperature variation across the surface, the thermal resistance is measured from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink.

• To define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to the point at which the leads attach to the case.

• If the temperature of the package case (T

) is determined by a thermocouple, thermal resistance is

computed from the value obtained by the equation (T

– TT)/PD.

As noted earlier, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. From a practical standpoint, that value is also suitable to determine the junction temperature from a case thermocouple reading in forced convection environments. In natural convection, the use of the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will yield an estimate of a junction temperature slightly higher than actual temperature. Hence, the new thermal metric, thermal characterization parameter or Ψ

, has been defined to be (TJ – TT)/PD. This value gives a better estimate of the junction temperature in natural convection when the surface temperature of the package is used. Remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. The recommended technique is to attach a 40-gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy.

4.2 Electrical Design Considerations

Use the following list of recommendations to ensure correct DSP operation.

• Provide a low-impedance path from the board power supply to each

pin on the DSP and from the

board ground to each GND pin.

• Use at least four 0.01–0.1 µF bypass capacitors for the core and PLL power and six 0.01–0.1 µF bypass

capacitors for I/O power positioned as closely as possible to the four sides of the package to connect the

power source to GND.

• Ensure that capacitor leads and associated printed circuit traces that connect to the chip

and GND pins

are less than 0.5 inch per capacitor lead.

• Use at least a four-layer PCB with two inner layers for

and GND.

CAUTION

This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (for example, either GND or V

Power Consumption Considerations

DSP56311 Technical Data, Rev. 8

Freescale Semiconductor 4-3

• Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal. This recommendation particularly applies to the address and data buses as well as the

IRQA, IRQB, IRQC, IRQD,

TA , and BG pins. Maximum PCB trace lengths on the order of 6 inches are recommended.

• Consider all device loads as well as parasitic capacitance due to PCB traces when you calculate capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the

and GND circuits.

• All inputs must be terminated (that is, not allowed to float) by CMOS levels except for the three pins with internal pull-up resistors (

TRST, TMS, DE).

• Take special care to minimize noise levels on the

CCP

, GNDP, and GNDP1 pins.

• The following pins must be asserted during power-up:

RESET and TRST. A stable EXTAL signal should be

supplied before deassertion of RESET. If the VCC reaches the required level before EXTAL is stable or other “required RESET duration” conditions are met (see Tab l e 2 - 7), the device circuitry can be in an uninitialized state that may result in significant power consumption and heat-up. Designs should minimize this condition to the shortest possible duration.

• Ensure that during power-up, and throughout the DSP56311 operation, V

CCQH

is always higher or equal to

the V

voltage level.

• If multiple DSP devices are on the same board, check for cross-talk or excessive spikes on the supplies due to synchronous operation of the devices.

• The Port A data bus (

D[0–23]), HI08, ESSI0, ESSI1, SCI, and timers all use internal keepers to maintain the

last output value even when the internal signal is tri-stated. Typically, no pull-up or pull-down resistors should be used with these signal lines. However, if the DSP is connected to a device that requires pull-up resistors (such as an MPC8260), the recommended resistor value is 10 KΩ or less. If more than one DSP must be connected in parallel to the other device, the pull-up resistor value requirement changes as follows:

—2 DSPs = 7 KΩ or less —3 DSPs = 4 KΩ or less —4 DSPs = 3 KΩ or less —5 DSPs = 2 KΩ or less —6 DSPs = 1.5 KΩ or less

4.3 Power Consumption Considerations

Power dissipation is a key issue in portable DSP applications. Some of the factors affecting current consumption are described in this section. Most of the current consumed by CMOS devices is alternating current (ac), which is charging and discharging the capacitances of the pins and internal nodes. Current consumption is described by this formula:

Equation 3:

Where:

C = node/pin capacitance V = voltage swing f = frequency of node/pin toggle

Example 4-1. Current Consumption

For a Port A address pin loaded with 50 pF capacitance, operating at 3.3 V, with a 66 MHz clock, toggling at its maximum possible rate (33 MHz), the current consumption is expressed in Equation 4.

CVf××=

DSP56311 Technical Data, Rev. 8

4-4 Freescale Semiconductor

Design Considerations

Equation 4:

The maximum internal current (I

CCI

max) value reflects the typical possible switching of the internal buses on best-

case operation conditions—not necessarily a real application case. The typical internal current (I

CCItyp

) value reflects the average switching of the internal buses on typical operating conditions. Perform the following steps for applications that require very low current consumption:

1. Set the EBD bit when you are not accessing external memory.

2. Minimize external memory accesses, and use internal memory accesses.

3. Minimize the number of pins that are switching.

4. Minimize the capacitive load on the pins.

5. Connect the unused inputs to pull-up or pull-down resistors.

6. Disable unused peripherals.

7. Disable unused pin activity (for example, CLKOUT, XTAL).

One way to evaluate power consumption is to use a current-per-MIPS measurement methodology to minimize specific board effects (that is, to compensate for measured board current not caused by the DSP). A benchmark power consumption test algorithm is listed in Appendix A. Use the test algorithm, specific test current measurements, and the following equation to derive the current-per-MIPS value.

Equation 5:

Where:

typF2

= current at F2

typF1

= current at F1

F2 = high frequency (any specified operating frequency) F1 = low frequency (any specified operating frequency lower than F2)

Note: F1 should be significantly less than F2. For example, F2 could be 66 MHz and F1 could be 33 MHz. The

degree of difference between F1 and F2 determines the amount of precision with which the current rating can be determined for an application.

4.4 PLL Performance Issues

The following explanations should be considered as general observations on expected PLL behavior. There is no test that replicates these exact numbers. These observations were measured on a limited number of parts and were not verified over the entire temperature and voltage ranges.

4.4.1 Phase Skew Performance

The phase skew of the PLL is defined as the time difference between the falling edges of EXTAL and CLKOUT for a given capacitive load on

CLKOUT, over the entire process, temperature and voltage ranges. As defined in Figure 2-

2, External Clock Timing, on page 2-5 for input frequencies greater than 15 MHz and the MF ≤4, this skew is

greater than or equal to 0.0 ns and less than 1.8 ns; otherwise, this skew is not guaranteed. However, for MF < 10 and input frequencies greater than 10 MHz, this skew is between −1.4 ns and +3.2 ns.

4.4.2 Phase Jitter Performance

The phase jitter of the PLL is defined as the variations in the skew between the falling edges of EXTAL and CLKOUT for a given device in specific temperature, voltage, input frequency, MF, and capacitive load on

CLKOUT. These

variations are a result of the PLL locking mechanism. For input frequencies greater than 15 MHz and MF ≤ 4, this jitter is less than ±0.6 ns; otherwise, this jitter is not guaranteed. However, for MF < 10 and input frequencies greater than 10 MHz, this jitter is less than ±2 ns.

DSP56311 Technical Data, Rev. 8

4-6 Freescale Semiconductor

Design Considerations

4.4.3 Frequency Jitter Performance

The frequency jitter of the PLL is defined as the variation of the frequency of CLKOUT. For small MF (MF < 10) this jitter is smaller than 0.5 percent. For mid-range MF (10 < MF < 500) this jitter is between 0.5 percent and approximately 2 percent. For large MF (MF > 500), the frequency jitter is 2–3 percent.

4.5 Input (EXTAL) Jitter Requirements

The allowed jitter on the frequency of EXTAL is 0.5 percent. If the rate of change of the frequency of EXTAL is slow (that is, it does not jump between the minimum and maximum values in one cycle) or the frequency of the jitter is fast (that is, it does not stay at an extreme value for a long time), then the allowed jitter can be 2 percent. The phase and frequency jitter performance results are valid only if the input jitter is less than the prescribed values.
