MPC885/MPC880
Hardware Specifications
This hardware specification contains detailed information on
power considerations, DC/AC electrical characteristics, and AC
timing specifications for the MPC885/MPC880 (refer to
Table 1
for the list of devices). The MPC885 is the superset device of the
MPC885/MPC880 family. The CPU on the MPC885/MPC880 is
a 32-bit PowerPC鈩?core that incorporates memory management
units (MMUs) and instruction and data caches and that
implements the PowerPC instruction set.
