CY7C1520KV18-250BZC

CY7C1520KV18-250BZC is a 72-Mbit (2M × 36) synchronous pipelined DDR-II SRAM with two-word burst architecture. It runs up to 250 MHz clock and transfers data at up to 500 MHz DDR rate. The device uses 1.8 V VDD (1.7–1.9 V) with HSTL I/O at VDDQ 1.4 V to VDD, and integrates echo clocks (CQ/CQ), a PLL, programmable output impedance (ZQ), and IEEE 1149.1 JTAG in a 165-ball FBGA package.
