CY7C1312KV18-250BZC

Product Summary

The CY7C1312KV18-250BZC is a 1.8 V Synchronous Pipelined SRAM, equipped with QDR IIarchitecture. QDR II architecture consists of two separate ports:the read port and the write port to access the memory array. The CY7C1312KV18-250BZC has dedicated data outputs to support read operationsand the write port has dedicated data inputs to support writeoperations. All synchronous inputs pass through input registers controlled bythe K or K input clocks. All data outputs pass through outputregisters controlled by the C or C (or K or K in a single clockdomain) input clocks. Writes are conducted with on-chipsynchronous self-timed write circuitry.
