CY7C25652KV18-500BZXC is a 72-Mbit QDR II+ synchronous pipelined SRAM (2M × 36) with separate DDR read and write ports for concurrent transactions and four-word burst transfers. It runs up to 500 MHz and uses 1.8 V VDD (1.7–1.9 V) with VDDQ from 1.4 V to VDD. On-die termination supports D, BWS, and K/K, and echo clocks, QVLD, PLL, and IEEE 1149.1 JTAG aid high-speed capture and test.
