The 603 is the first low-power implementation of the PowerPC microprocessor family of RISC
microprocessors. The 603 implements the 32-bit portion of the PowerPC Architecture™ specification,
which provides 32-bit effective addresses, integer data types of 8, 16, and 32 bits, and floating-point data
types of 32 and 64 bits. For 64-bit PowerPC microprocessors, the PowerPC architecture provides 64-bit
integer data types, 64-bit addressing, and other features required to complete the 64-bit architecture.
The 603 provides four software controllable power -saving modes. Three of the modes (doze, nap, and sleep
modes) are static in nature, and progressively reduce the amount of power dissipated by the processor. The
fourth is a dynamic power management mode that causes the functional units in the 603 to automatically
enter a low-power mode when the functional units are idle without affecting operational performance,
software execution, or any external hardware.
The 603 is a superscalar processor capable of issuing and retiring as many as three instructions per clock.
Instructions can execute out of order for increased performance; howe ver , the 603 makes completion appear
sequential.
The 603 integrates five execution units—an integer unit (IU), a floating-point unit (FPU), a branch
processing unit (BPU), a load/store unit (LSU), and a system register unit (SRU). The ability to ex ecute five
instructions in parallel and the use of simple instructions with rapid execution times yield high efficiency
and throughput for 603-based systems. Most integer instructions execute in one clock cycle. The FPU is
pipelined so a single-precision multiply-add instruction can be issued every clock cycle.
The 603 provides independent on-chip, 8-Kbyte, two-way set-associative, physically addressed caches for
instructions and data and on-chip instruction and data memory management units (MMUs). The MMUs
contain 64-entry, two-way set-associative, data and instruction translation lookaside buffers (DTLB and
ITLB) that provide support for demand-paged virtual memory address translation and variable-sized block
translation. The TLBs and caches use a least recently used (LRU) replacement algorithm. The 603 also
supports block address translation through the use of two independent instruction and data block address
translation (IBAT and DBAT) arrays of four entries each. Effective addresses are compared simultaneously
with all four entries in the BAT array during block translation. In accordance with the Po werPC architecture,
if an effective address hits in both the TLB and BAT array, the BAT translation takes priority.
The 603 has a selectable 32- or 64-bit data bus and a 32-bit address bus. The 603 interface protocol allows
multiple masters to compete for system resources through a central external arbiter. The 603 provides a
three-state coherency protocol that supports the exclusiv e, modified, and invalid cache states. This protocol
is a compatible subset of the MESI (modified/exclusive/shared/invalid) four-state protocol and operates
coherently in systems that contain four-state caches. The 603 supports single-beat and burst data transfers
for memory accesses; it also supports both memory-mapped I/O and direct-store addressing.
The 603 uses an advanced, 3.3-V CMOS process technology and maintains full interface compatibility with
TTL devices.

Notes : 1. Rise and fall times for the SYSCLK input are measured from 0.4 V to 2.4 V.
2. This is the sum total of both short- and long-term jitter, and is guaranteed by design.
3. Timing is guaranteed by design and characterization, and is not tested.
4. PLL relock time is the maximum amount of time required for PLL lock after a stable Vdd and SYSCLK are reached
during the power-on reset sequence. This specification also applies when the PLL has been disabled and
subsequently re-enabled during sleep mode. Also note that HRESET
bus clocks after the PLL relock time (100 µ s) during the power-on reset sequence.
5. Caution : The SYSCLK frequency and PLL_CFG0–PLL_CFG3 settings must be chosen such that the resulting
SYSCLK (bus) frequency, CPU (core) frequency, and PLL (VCO) frequency do not exceed their respective
maximum or minimum operating frequencies. Refer to the PLL_CFG0–PLL_CFG3 signal description in Section 1.7,
“System Design Information,” for valid PLL_CFG0–PLL_CFG3 settings, and to Section 1.8, “Ordering Information,”

1.7 System Design Information
This section provides electrical and thermal design recommendations for successful application of the 603.
1.7.1 PLL Configuration
A 603 part number corresponds to a particular combination of internal (CPU core) and SYSCLK (external
bus) frequency ranges which the device has been tested to. The PLL is configured by the
PLL_CFG0–PLL_CFG3 pins. For a given SYSCLK (bus) frequency, the PLL configuration pins set the
internal CPU frequency of operation.

1111Clock off
Notes: 1. Some PLL configurations may select bus, CPU, or PLL frequencies which are not useful, not
supported, or not tested for by the 603. PLL frequencies (sho wn in parenthesis in Table 10) should
not fall below 133 MHz, and should not exceed 200 MHz.
2. In PLL bypass mode, the SYSCLK input signal clocks the internal processor directly, the PLL is
disabled, and the bus mode is set for 1:1 mode operation. This mode is intended for factory use
only. Note that the AC timing specifications given in this document do not apply in PLL bypass
mode.
3. In clock-off mode, no clocking occurs inside the 603 regardless of the SYSCLK input.
4. PLL_CFG0–PLL_CFG1 signals select the CPU-to-bus ratio (1:1, 2:1, 3:1, 4:1),
PLL_CFG2–PLL_CFG3 signals select the CPU-to-PLL multiplier (x2, x4, x8).

1.7.2 PLL Power Supply Filtering
The AVdd power signal is pro vided on the 603 to provide po wer to the clock generation phase-lock loop. To
ensure stability of the internal clock, the power supplied to the AVdd input signal should be filtered using a
circuit similar to the one shown in Figure 12. The circuit should be placed as close as possible to the AVdd
pin to ensure it filters out as much noise as possible.

1.7.3 Decoupling Recommendations
Due to the 603’s dynamic power management feature, large address and data buses, and high operating
frequencies, the 603 can generate transient power surges and high frequency noise in its power supply,
especially while driving large capacitive loads. This noise must be prevented from reaching other
components in the 603 system, and the 603 itself requires a clean, tightly regulated source of power.
Therefore, it is recommended that the system designer place a decoupling capacitor with a low ESR
(effective series resistance) rating at each Vdd and OVdd pin of the 603.
These capacitors should range in value from 220 pF to 10 µF to provide both high and low frequency
filtering, and should be placed as close as possible to their associated Vdd pin. Surface-mount tantulum or
ceramic devices are preferred. It is also recommended that these decoupling capacitors receive their power
from Vdd and GND power planes in the PCB, utilizing short traces to minimize inductance in the traces.
Power and ground connections must be made to all external Vdd and GND pins of the 603.
1.7.4 Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. Unused acti ve-low inputs should be connected to Vdd. Unused acti ve-high inputs should be connected
to GND.
1.7.5 Thermal Management Information for the Motorola Package
This section provides a thermal management example for the 603; this example is based on a typical desktop
configuration using a 240 lead, 32 mm x 32 mm, Motorola wire-bond CQFP package. The heat sink used
for this data is a pinfin configuration from Thermalloy, part number 2338.
1.7.5.1 Thermal Characteristics for the Motorola Wire-Bond CQFP Package
The thermal characteristics for a wire-bond CQFP package are as follows:
Thermal resistance (junction-to-case) = R
1.7.5.2 Thermal Management Example

package with thermal grease.

In this environment, it can be assumed that all the heat is dissipated to the ambient through the heat sink, so
the junction-to-ambient thermal resistance is the sum of the resistances from the junction to the case, from
the case to the heat sink, and from the heat sink to the ambient.
Note that verification of external thermal resistance and case temperature should be performed for each
application. Thermal resistance can vary considerably due to many factors including degree of air
turbulence.
For a power dissipation of 2.5 Watts in an ambient temperature of 40
measured above, the junction temperature of the device would be as follows:
T
