70 -- PEP MODULAR SRAM MEMORY BOARDS SOL DAAD05-97-B-0010 DUE 022897 POC Contract Specialist Kevin Clark 410-278-0890 (Site Code DAAD05) The U.S. Army Aberdeen Proving Ground Test Center has a requirement to purchase forty (40) PEP Modular Static RAM Memory Modules. Technical requirements are as follows: 1) The memory model is VMEM-S2 which is a Static RAM Memory Module that shall have 8 Mbytes capacity. Size standard for the boards shall be 3U (Single Height) VME-BUS. 2) The boards shall have two independent memory banks containing sixteen 32-PIN sockets. The 8 Mbyte configuration shall have sixteen 512K*8 SRAM memory devices installed. This configuration shall have both banks being fully populated with high-speed SRAM chips. The access speed of either memory bank shall be separately configurable, but shall be less than 100 nanoseconds. 3) Data retention shall be provided by an on-board battery backup for the entire 8 Mbytes of SRAM, enabling data retention to be bank selectable. The battery backup source may be provided by either the VME+5V Stand-by line or with a VMEM-S2 on-board Lithium Cell Battery that has a data retention capacity of up to 300 days. 4) Boards shall have accidental erasure of SRAM, avoided with the VMEM-S2's software write protection circuit. This is an important safeguard that shall be software controlled via control bit. 5) The boards should provide as a standard VME-bus slave interface (A24:D16) that has a low power consumption and ruggedized construction. 6) The VMEM-S2 board shall operate in standard and extended temperature ranges (-55C TO +85C). 7) Board size shall be 100mm X 115mm. 8) Connector shall be DIN-41612 style-C (96-PIN). 9) The address modifier codes shall be jumper selectable in the following ranges: 3E/3D/3A/39/2D/29/1F-18/17-10/38-3F. 10) Boards shall have an operable humidity range of 5% TO 95% non-condensing. To receive a copy of the solicitation you may send your requests by fax to (410) 278-0899/0900 or mail in a written request to the Directorate of Contracting, ATTN: Bid Clerk, Bldg. 4118 Susquehanna Blvd., Aberdeen Proving Ground, MD 21005- 5001.
