CY7C1645KV18-450BZXI is a 144-Mbit QDR II+ synchronous pipelined SRAM organized as 4 M × 36 with separate read and write ports to eliminate data bus turnarounds. It supports four-word burst transfers with 2.0-cycle read latency (DOFF HIGH), DDR I/O at 450 MHz clock (900 MHz data rate), and operates from 1.8 V core with 1.4 V to VDD I/O supply. It is offered in a 165-ball Pb-free FBGA, industrial grade.
