Functional Description

The CY7C1316JV18, CY7C1916JV18, CY7C1318JV18, and CY7C1320JV18 are 1.8V Synchronous Pipelined SRAMs equipped with DDR-II architecture. The DDR-II consists of an SRAM core with advanced synchronous peripheral circuitry and a one-bit burst counter.

Features

■ 18-Mbit density (2M x 8, 2M x 9, 1M x 18, 512K x 36)

■ 300 MHz clock for high bandwidth

■ 2-word burst for reducing address bus frequency

■ Double Data Rate (DDR) interfaces

(data transferred at 600 MHz) at 300 MHz

■ Two input clocks (K and K) for precise DDR timing

? SRAM uses rising edges only

■ Two input clocks for output data (C and C) to minimize clock

skew and flight time mismatches

■ Echo clocks (CQ and CQ) simplify data capture in high-speed

systems

■ Synchronous internally self-timed writes

■ DDR-II operates with 1.5 cycle read latency when the DLL is

enabled

■ Operates similar to a DDR-I device with 1 cycle read latency in

DLL off mode

■ 1.8V core power supply with HSTL inputs and outputs

■ Variable drive HSTL output buffers

■ Expanded HSTL output voltage (1.4V–VDD)

■ Available in 165-Ball FBGA package (13 x 15 x 1.4 mm)

■ Offered in both Pb-free and non Pb-free packages

■ JTAG 1149.1 compatible test access port

■ Delay Lock Loop (DLL) for accurate data placement
