Product Brief
MPC565/MPC566 RISC MCU with Code
Compression Option
Features
The MPC565 / MPC566 key features are as follows. The information inside boxes are optional features.
40 MHz / 56 MHz operation
56 MHz operation is available as an option.
— -40

– 125
°
C ambient temperature
— 2.6 V
±
0.1 V external bus
External bus is compatible with external memory devices operating from 2.5 V to 3.4 V.
Extended voltage range (2.7 – 3.4 V) degrades data drive timing by 1.1 ns on date writes.
— 2.6
±
0.1 V internal logic
— 5-V I/O (5.0
±
0.25 V)
High performance RISC CPU system
— High performance core
Single issue integer core
Instruction set compatible with PowerPC instruction set architecture
Precise exception model
Floating point
Code compression supported on the MPC566
— Compression reduces usage of internal or external flash memory
— Compression optimized for automotive (non-cached) applications
— New compression scheme increases compression performance to 40% – 50% compres-
sion
— 4-Kbyte static DECRAM can be used as memory if Compression is not used.
— General-purpose I/O support
On address (24) and data (32) pins
16 GPIO in MIOS14
Many peripheral pins can be used as GPIO when not used as primary functions
2.6-V outputs on external bus pins
Extensive system development support
— On-chip watchpoints and breakpoints
— Program flow tracking
— Background debug mode (BDM)
Key Feature Details
MPC500 System Interface (USIU, BBC, L2U)
Periodic interrupt timer, bus monitor, clocks, decrementer and time base
Clock synthesizer, power management, reset controller
External bus tolerates 5-V inputs, provides 3.3-V outputs
Enhanced interrupt controller supports a separate interrupt vector for up to eight external and 40
