The CY7C1614KV18-250BZI is a 144-Mbit QDR II synchronous pipelined burst SRAM in a 4M × 36 organization with separate read and write ports. It supports two-word burst transfers with DDR interfaces and operates up to 250 MHz. Core supply is 1.8 V with VDDQ from 1.4 V to VDD. DOFF selects 1.5-cycle (QDR II) or 1-cycle (QDR I) read latency, and echo clocks plus an on-chip PLL aid timing.
