Overview
The XVME-103 RAM/ROM Memory Module is a single-high, VMEbus-compatible board. It can accommodate up to 4 MB of RAM, 8 MB of EPROM, 4 MB of Flash or 4 MB of EEPROM.
The module is designed with an on-board battery backup circuit to provide power to CMOS RAM devices in the event of a power failure.
The XVME-103 has eight 32-pin JEDEC sockets that are logically divided into two separate memory banks, containing four sites each.
Each bank is designed to employ memory devices of the same type and speed, and each bank can be independently configured (via jumpers and switches).
Power monitoring circuitry on the XVME-103 prevents access to memory, and optionally asserts SYSREST if the supply voltage falls below 4.75 VDC. This circuit also: checks the backup power source during power-up, will turn on a front panel “battery low” LED, and can be configured to assert SYSFAIL if the backup voltage is insufficient to
back-up CMOS memory devices.
