MM-6795C 64MB VME/VME64 NVRAM Memory Module


  • CMOS NVRAM: 16, 32, 64MB
  • On-board timer provides 1 usec to 16 msec in 1 usec increments for Flash timing requirements
  • Compatible with VME/VME64 A32/A24/D64/D32/D16/D8 (UAT) (BLT) (MBLT)
  • Data retention for CMOS, 3 years with lithium batteries, 4 weeks with rechargeable NiCad batteries
  • Cycle/Access Time CMOS NVRAM: 150/100 nsec Flash memory: 200/150 nsec (read only mode)
  • Block Transfer of 256 bytes for VME and 2KB for VME64
  • Two on-board, redundant, fused lithium or NiCad batteries
  • Module Selection on 1MB boundaries, switch-selectable

A high-speed, high density memory module, the MM-6795C provides up to 64MB of CMOS NVRAM on one board. The MM-6795C is VME/VME64 bus compatible and operates with block transfer (BLT) of 256 bytes for VME and 2KB for VME64 (MBLT).

The MM-6795C has three on-board, redundant, fused batteries to retain memory in the event of power loss. Batteries may be either rechargeable NiCad or non-rechargeable lithium types. On-board LED's and a control status indicate battery condition.

Reliability is ensured by burn-in and running memory diagnostics that check operation for 48 hours while temperature-cycling boards from 0 - 60°C.
