CY7C1565KV18-400BZI is a 72-Mbit QDR II+ synchronous pipelined SRAM (2M × 36) with separate read and write ports and four-word burst operation. It supports DDR transfers on both ports using two input clocks (K/K) and provides echo clocks (CQ/CQ) and QVLD for data capture. Core supply is 1.7 V to 1.9 V with VDDQ from 1.4 V to VDD. The -400 speed grade supports 400 MHz operation in a 165-ball FBGA.
