功能描述

The CY7C1381D/CY7C1383D/CY7C1383F is a 3.3 V, 512 K × 36 and 1 M × 18 synchronous flow through SRAMs, 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 automatically for the rest of the burst access. All synchronous inputs are gated by registers controlled by a positive edge triggered clock input (CLK).
