RAM300 modules of 16, 32, 64, 128, or 256MB are available for memory
expansion. The ECC DRAM is controlled by the Falcon memory
controller chip set. The Falcon ASICs perform two-way interleaving, with
double-bit error detection and single-bit error correction.
In addition to the ECC DRAM, the RAM300 module supplies 4MB or
8MB of additional soldered-in 64-bit Flash memory. A jumper header (J6)
tells the Falcon chip set where in memory to fetch the board reset vector.
Depending on the configuration of J6, resets execute either from Flash
memory bank A or from bank B.
Compact FLASH Memory Card
The MCP750 supports a single EIDE compatible Compact FLASH
Memory Card off of the PBC Primary EIDE interface. Currently available
Compact FLASH memory cards provide from 2 Mbytes to 24 Mbytes of
formatted capacity. Once configured, this memory will appear as a
standard ATA (EIDE) disk drive.
TMCP700 Transition Module
The TMCP700 transition module is used in conjunction with all models of
the MCP750 base board:
The features of the TMCP700 include:
❏
A parallel printer port (IEEE 1284-I compliant)
❏
Two EIA-232-D asynchronous serial ports (identified
as
COM1
and
COM2
on the front panel)
❏
Two synchronous serial ports (
SERIAL
3
and
SERIAL
4
on the front
panel) configured for EIA-232-D, EIA-530, V.35, or X.21 protocols
❏
Two Universal Serial Bus (USB) ports
❏
Two 60-pin Serial Interface Module (SIM) connectors
❏
A 40-pin header for the secondary EIDE port
❏
Two 64-pin headers for PMC IO
