CY7C1643KV18-450BZI is a 144-Mbit QDR II+ synchronous pipelined SRAM (8 M × 18) with separate read and write ports and four-word burst operation. It supports 450 MHz clocks with DDR transfers (900 MHz data rate) and 2.0-cycle read latency. The device runs from 1.7–1.9 V core (VDD) with 1.4 V–VDD I/O (VDDQ) over the industrial range of -40 to +85°C in a 165-ball FBGA, and is JTAG 1149.1 compatible.
