The EDI88130CS is a high speed, high performance, 128Kx8 bits monolithic Static RAM. It has eight bi-directional input-output lines to provide simultaneous access to all bits. The EDI88130CS provides an additional chip enable line which provides system memory security during power down in non-battery backed up systems and memory banking in high speed battery backed systems where large multiple pages of memory are required.
The EDI88130CS is a high‑reliability 128K×8 monolithic SRAM offered by White Electronic Designs. It provides a range of access times from 15 ns to 55 ns, TTL‑compatible I/O, and an optional low‑power version (EDI88130LPS) with 2 V data‑retention for battery‑back‑up applications. The device is qualified for commercial, industrial and military temperature ranges and complies with MIL‑PRF‑38535.
The datasheet lists absolute maximum ratings, recommended operating conditions, DC and AC characteristics for read and write cycles, and detailed package dimensions for several 32‑lead formats (DIP, SOJ, LCC, Flatpack). Ordering information and pin‑out diagrams are also provided.
