TPM749Microcontroller with TrackPoint microcode from IBM

1996 May 01 853-1831 16753

DESCRIPTION

The Philips Semiconductors TPM749 is a small package, low cost, ROM-coded 80C51 with IBM’s TrackPoint pointing algorithms and control code. TrackPoint is the result of years of human factors research and innovation at IBM. The result is a “velocity sensitive” pointing solution more efficient and easier to use than “position sensitive” devices such as the mouse, the trackball, or the touchpad.

IBM has licensed Philips Semiconductors to sell microcontrollers with TrackPoint code. By purchasing a TPM from Philips, the purchaser becomes a sub-licensee of Philips. The selling price of Philips’ TPM includes the royalties for IBM’s intellectual property, which Philips in turn pays to IBM. Customers for TPMs do not need to sign any licensing agreement with either IBM or Philips. This code is the intellectual property of IBM, which is covered by numerous patents, and must be treated accordingly.

The TPM is fabricated with Philips high-density CMOS technology. Philips epitaxial substrate minimizes CMOS latch-up sensitivity.

The TPM contains a 2k × 8 ROM, a 64 × 8 RAM, 21 I/O lines, a 16-bit auto-reload counter/timer, a fixed-priority level interrupt structure, an on-chip oscillator, a five channel multiplexed 8-bit A/D converter, and an 8-bit PWM output.

The TPM supports two power reduction modes of operation referred to as the idle mode and the power-down mode.

PIN DESCRIPTION

MNEMONIC PIN NO. TYPE NAME AND FUNCTION

12 I Circuit Ground Potential.

28 I Supply voltage during normal, idle, and power-down operation.

P0.0–P0.4 8–6

23, 24

I/O Port 0: Port 0 is a 5-bit bidirectional port. Port 0.0–P0.2 are open drain. Port 0.0–P0.2 pins that have

1s written to them float, and in that state can be used as high-impedance inputs. P0.3–P0.4 are bidirectional I/O port pins with internal pull-ups. These pins are driven low if the port register bit is written with a 0. The state of the pin can always be read from the port register by the program. Port 0.3 and 0.4 have internal pull-ups that function identically to port 3. Pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs.

While P0.0 anbd P0.1 differ from “standard TTL” characteristics, they are close enough for the pins to still be used as general-purpose I/O.

6 I VPP (P0.2) – Programming voltage input. 7 I OE (P0.1) – Input which specifies verify mode (output enable).

OE = 1 output enabled (verify mode).

8 I ASEL (P0.0) – Input which indicates which bits of the EPROM address are applied to port 3.

ASEL = 0 low address byte available on port 3. ASEL = 1 high address byte available on port 3 (only the three least significant bits are used).

P1.0–P1.7 13–17,

20–22

I/O Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups. Port 1 pins that have 1s written to

them are pulled high by the internal pull-ups and can be used as inputs. P0.3–P0.4 pins are bidirectional I/O port pins with internal pull-ups. As inputs, port 1 pins that are externally pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: I

). Port 1 also

serves the special function features of the SC80C51 family as listed below: 20 I INT0 (P1.5): External interrupt. 21 I INT1 (P1.6): External interrupt. 22 I T0 (P1.7): Timer 0 external input.

13–17 I ADC0 (P1.0)–ADC4 (P1.4): Port 1 also functions as the inputs to the five channel multiplexed A/D

converter. These pins can be used as outputs only if the A/D function has been disabled. These pins

can be used as digital inputs while the A/D converter is enabled.

Port 1 serves to output the addressed EPROM contents in the verify mode and accepts as inputs the

value to program into the selected address during the program mode.

P3.0–P3.7 5–1,

27–25

I/O Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have 1s written to

them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are

externally being pulled low will source current because of the pull-ups. (See DC Electrical

Characteristics: IIL). Port 3 also functions as the address input for the EPROM memory location to be

programmed (or verified). The 11-bit address is multiplexed into this port as specified by P0.0/ASEL.

RST 9 I Reset: A high on this pin for two machine cycles while the oscillator is running resets the device. An

internal diffused resistor to V

permits a power-on RESET using only an external capacitor to VCC. After the device is reset, a 10-bit serial sequence, sent LSB first, applied to RESET, places the device in the programming state allowing programming address, data and V

to be applied for programming

or verification purposes. The RESET serial sequence must be synchronized with the X1 input.

X1 11 I Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator circuits. X1

also serves as the clock to strobe in a serial bit stream into RESET to place the device in the programming state.

X2 10 O Crystal 2: Output from the inverting oscillator amplifier. AV

19 I Analog supply voltage and reference input.

18 I Analog supply and reference ground.

NOTE:

1. AV

(reference ground) must be connected to 0V (ground). AVCC (reference input) cannot differ from VCC by more than ±0.2V, and must be

in the range 4.5V to 5.5V.

OSCILLATOR CHARACTERISTICS

X1 and X2 are the input and output, respectively, of an inverting amplifier which can be configured for use as an on-chip oscillator.

To drive the device from an external clock source, X1 should be driven while X2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, because the input to the internal clock circuitry is through a divide-by-two flip-flop. However, minimum and maximum high and low times specified in the data sheet must be observed.

IDLE MODE

The TPM includes the 80C51 power-down and idle mode features. In idle mode, the CPU puts itself to sleep while all of the on-chip peripherals except the A/D and PWM stay active. The functions that continue to run while in the idle mode are Timer 0, Timer I, and the interrupts. The instruction to invoke the idle mode is the last instruction executed in the normal operating mode before the idle mode is activated. The CPU contents, the on-chip RAM, and all of the special function registers remain intact during this mode. The idle mode can be terminated either by any enabled interrupt (at which time the process is picked up at the interrupt service routine and continued), or by a hardware reset which starts the processor in the same manner as a power-on reset. Upon powering-up the circuit, or exiting from idle mode, sufficient time must be allowed for stabilization of the internal analog reference voltages before an A/D conversion is started.

POWER-DOWN MODE

In the power-down mode, the oscillator is stopped and the instruction to invoke power-down is the last instruction executed. Only the contents of the on-chip RAM are preserved. A hardware reset is the only way to terminate the power-down mode. The control bits for the reduced power modes are in the special function register PCON.

* Except for PWM output (P0.4).

I/O Ports

The I/O pins provided by the TPM consist of port 0, port 1, and port 3.

Port 0

Port 0 is a 5-bit bidirectional I/O port and includes alternate functions on some pins of this port. Pins P0.3 and P0.4 are provided with internal pullups while the remaining pins (P0.0, P0.1, and P0.2) have open drain output structures. The alternate function for port P0.4 is PWM output.

If the alternate function PWM is not being used, then this pin may be used as an I/O port.

Port 1

Port 1 is an 8-bit bidirectional I/O port whose structure is identical to the 80C51, but also includes alternate input functions on all pins. The alternate pin functions for port 1 are:

P1.0-P1.4 - ADC0-ADC4 - A/D converter analog inputs P1.5 INT0

- external interrupt 0 input

P1.6 INT1

- external interrupt 1 input

P1.7 - T0 - timer 0 external input If the alternate functions INT0

, INT1, or T0 are not being used, these pins may be used as standard I/O ports. It is necessary to connect AV

and AVSS to VCC and VSS, respectively, in order to use P1.5, P1.6, and P1.7 pins as standard I/O pins. When the A/D converter is enabled, the analog channel connected to the A/D may not be used as a digital input; however, the remaining analog inputs may be used as digital inputs. They may not be used as digital outputs. While the A/D is enabled, the analog inputs are floating.

Port 3

Port 3 is an 8-bit bidirectional I/O port whose structure is identical to the 80C51. Note that the alternate functions associated with port 3 of the 80C51 have been moved to port 1 of the TPM (as applicable). See Figure 1 for port bit configurations.

NOTE:

Because the analog to digital converter has a sampled-data comparator, the input looks capacitive to a source. When a conversion is initiated, switch Sm closes for 8tcy (8µs @ 12MHz crystal frequency) during which time capacitance Cs + Cc is charged. It should be noted that the sampling causes the analog input to present a varying load to an analog source.

A/D CONVERTER PARAMETER DEFINITIONS

The following definitions are included to clarify some specifications given and do not represent a complete set of A/D parameter definitions.

Absolute Accuracy Error

Absolute accuracy error of a given output is the difference between the theoretical analog input voltage to produce a given output and the actual analog input voltage required to produce the same code. Since the same output code is produced by a band of input voltages, the “required input voltage” is defined as the midpoint of the band of input voltage that will produce that code. Absolute accuracy error not specified with a code is the maximum over all codes.

Nonlinearity

If a straight line is drawn between the end points of the actual converter characteristics such that zero offset and full scale errors are removed, then non-linearity is the maximum deviation of the code transitions of the actual characteristics from that of the straight line so constructed. This is also referred to as relative accuracy and also integral non-linearity.

Differential Non-Linearity

Differential non-linearity is the maximum difference between the actual and ideal code widths of the converter. The code widths are the differences expressed in LSB between the code transition points, as the input voltage is varied through the range for the complete set of codes.

Gain Error

Gain error is the deviation between the ideal and actual analog input voltage required to cause the final code transition to a full-scale output code after the offset error has been removed. This may sometimes be referred to as full scale error.

Offset Error

Offset error is the difference between the actual input voltage that causes the first code transition and the ideal value to cause the first code transition. This ideal value is 1/2 LSB above V

ref–

Channel to Channel Matching

Channel to channel matching is the maximum difference between the corresponding code transitions of the actual characteristics taken from different channels under the same temperature, voltage and frequency conditions.

Crosstalk

Crosstalk is the measured level of a signal at the output of the converter resulting from a signal applied to one deselected channel.

Total Error

Maximum deviation of any step point from a line connecting the ideal first transition point to the ideal last transition point.

Relative Accuracy

Relative accuracy error is the deviation of the ADC’s actual code transition points from the ideal code transition points on a straight line which connects the ideal first code transition point and the final code transition point, after nullifying offset error and gain error. It is generally expressed in LSBs or in percent of FSR.

NOTES:

1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section of this specification is not implied.

2. Under steady state (non-transient) conditions, I

must be externally limited as follows:

Maximum I

per port pin: 10mA

Maximum I

per 8-bit port: 26mA

Maximum total I

for all outputs: 67mA

If I

exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed

test conditions.

3. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima.

4. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V

unless otherwise

noted.

8. Load capacitance for ports = 80pF.

9. The resistor ladder network is not disconnected in the power down or idle modes. Thus, to conserve power, the user may remove AV

10.If the A/D function is not required, or if the A/D function is only needed periodically, AV

may be removed without affecting the operation of

the digital circuitry. Contents of ADCON and ADAT are not guaranteed to be valid. If AV

is removed, the A/D inputs must be lowered to

less than 0.5V. Digital inputs on P1.0–P1.4 will not function normally.

11.These parameters do not apply to P1.0–P1.4 if the A/D function is enabled.
