Overview
The MPC866/859 is a derivative of Freescale’s MPC860
PowerQUICC™ family of devices. It 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 MPC866/859/859DSL provides
enhanced ATM functionality over that of other ATM-enabled
members of the MPC860 family.

For more details on the MPC852T, please refer to the
MPC852T Hardware Specifications.
The following list summarizes the key MPC866/859 features:
•
Embedded single-issue, 32-bit PowerPC™ core (implementing the PowerPC architecture) with
thirty-two 32-bit general-purpose registers (GPRs)
— The core performs branch prediction with conditional prefetch, without conditional execution
— 4- or 8-Kbyte data cache and 4- or 16-Kbyte instruction cache (see
Table 1)
– 16-Kbyte instruction cache (MPC866P and MPC859P) is four-way, set-associative with 256 sets;
4-Kbyte instruction cache (MPC866T, MPC859T, and MPC859DSL) is two-way, set-associative
with 128 sets.
– 8-Kbyte data cache (MPC866P and MPC859P) is two-way, set-associative with 256 sets; 4-Kbyte
data cache(MPC866T, MPC859T, and MPC859DSL) is two-way, set-associative with 128 sets.
– Cache coherency for both instruction and data caches is maintained on 128-bit (4-word) cache
blocks
– Caches are physically addressed, implement a least recently used (LRU) replacement algorithm, and
are lockable on a cache block basis.
— 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 spaces
and 16 protection groups.
— Advanced on-chip-emulation debug mode
The MPC866/859 provides enhanced ATM functionality over that of the MPC860SAR. The MPC866/859
adds major new features available in 'enhanced SAR' (ESAR) mode, including the following:
— Improved operation, administration, and maintenance (OAM) support
— OAM performance monitoring (PM) support
— Multiple APC priority levels available to support a range of traffic pace requirements
