CY7C1565KV18-450BZI is a 72-Mbit (2M × 36) 1.8 V QDR II+ synchronous SRAM with separate read and write ports and a four-word burst architecture (2.5-cycle read latency). The -450 speed grade supports up to 450 MHz clocks with DDR transfers, echo clocks (CQ/CQ) and QVLD for data capture, and an on-chip PLL. It supports VDDQ from 1.4 V to VDD and -40°C to +85°C industrial operation.
