Speaker Control

The MCP750 base board supplies a
module. The transition module contains a two pin jumper header (J13)
which allows the
to obtain a beep tone.

MPC750 Processor

The MCP750 is designed to support the enhanced version of the MPC750
360-pin BGA processor chip with 16MB to 256MB of ECC DRAM, 1MB
of level 2 cache (L2 cache), and up to 9MB of Flash memory. The L2 cache
and 1MB of 16-bit Flash memory reside on the MCP750 base board. The
ECC DRAM and 4MB or 8MB of additional (64-bit) Flash memory are
located on the RAM300 memory mezzanine.
The MPC750 is a 64-bit processor with 64KB on-chip cache (32KB data
cache and 32KB instruction cache). The L2 cache is implemented with an
on-chip, two way set associative tag memory and with external
synchronous SRAMs for data storage.
