General Description

The MCPN750A is a hot swappable CompactPCI, non-system slot, single- board computer equipped with an MPC750 PowerPC™ 750 Series microprocessor. The processor implements a backside cache controller and the board comes with 1MB of cache memory.

As shown in the Features section, the MCPN750A offers many standard features desirable in a CompactPCI computer system such as L2 cache, a PCI Bridge and Interrupt Controller, an ECC Memory Controller chipset, 5MB of linear FLASH memory, 16MB to 256MB of ECC-protected DRAM, interface to a CompactPCI bus, and several I/O peripherals.

I/O peripheral interfaces present onboard include 10BaseT/100BaseTX Ethernet, USB host controller, four asynchronous serial ports, a 512 x 8 Serial EEPROM, an ISA slave interface, a Fast EIDE interface and two PMC slots. Functions provided from the ISA bus include a real time clock, NVRAM, serial ports and status registers.
