Overview
1
The MPC885/MPC880 is a versatile single-chip integrated microprocessor and peripheral combination
that can be used in a variety of controller applications and communications and networking systems. The
MPC885/MPC880 provides enhanced ATM functionality, an additional fast Ethernet controller, a USB,
and an encryption block.

Overview
Features
Embedded MPC8xx core up to 133 MHz
Maximum frequency operation of the external bus is 80 MHz (in 1:1 mode)
— The 133-MHz core frequency supports 2:1 mode only.
— The 66-/80-MHz core frequencies support both the 1:1 and 2:1 modes.
Single-issue, 32-bit core (compatible with the Power Architecture definition) with thirty-two
32-bit general-purpose registers (GPRs)
— The core performs branch prediction with conditional prefetch and without conditional
— 8-Kbyte data cache and 8-Kbyte instruction cache (see
— MMUs with 32-entry TLB, fully associative instruction and data TLBs
— MMUs support multiple page sizes of 4, 16, and 512 Kbytes, and 8 Mbytes; 16 virtual address
— Advanced on-chip emulation debug mode
shows the functionality supported by MPC885/MPC880.

– Instruction cache is two-way, set-associative with 256 sets in 2 blocks
– Data cache is two-way, set-associative with 256 sets
– Cache coherency for both instruction and data caches is maintained on 128-bit (4-word)
– Caches are physically addressed, implement a least recently used (LRU) replacement
