Features
The major features of the MPC8272 are as follows:
Dual-issue integer (G2_LE) core
— A core version of the MPC603e microprocessor
— System core microprocessor supporting frequencies of 266-400 MHz
— Separate 16-Kbyte data and instruction caches:
– Four-way set associative
– Physically addressed
– LRU replacement algorithm
— PowerPC architecture-compliant memory management unit (MMU)
— Common on-chip processor (COP) test interface
— Supports bus snooping for cache coherency
— Floating-point unit (FPU) supports floating-point arithmetic
— Support for cache locking
Low-power consumption
Separate power supply for internal logic (1.5 V) and for I/O (3.3 V)
