4-Mbit (128K X 32) Flow-Through Sync SRAM

The CY7C1338G is a 128K x 32 synchronous cache RAM designed to Interface with high-speed Microprocessors with minimum glue Logic Maximum access delay from Clock rise is 6.5 ns (133-MHz version). A 2-bit on-chip Counter captures the first address in a burst and increments the address automati- cally for the rest of the burst access. All synchronous inputs are gated by Registers controlled by a positive-edge-triggered Clock Input (CLK). The synchronous inputs include all addresses, all data inputs, address-pipelining Chip Enable (CE ), depth-expansion Chip Enables (CE and CE ), Burst 1 2 3 Control inputs (ADSC, ADSP, and ADV), Write Enables (BW , and BWE), and Global Write (GW). Asynchronous [A:D] inputs include the Output Enable (OE) and the ZZ pin. By Cypress Semiconductor Corp.
