CY7C09349A

CY7C09359A

4K/8K x 18

Synchronous Dual-Port Static RAM

Features

鈥?True dual-ported memory cells which allow simulta-

neous access of the same memory location

鈥?Two Flow-Through/Pipelined devices

鈥?4K x 18 organization (CY7C09349A)

鈥?8K x 18 organization (CY7C09359A)

鈥?Three Modes

鈥?Flow-Through

鈥?Pipelined

鈥?Burst

鈥?Pipelined output mode on both ports allows fast

100-MHz cycle time

鈥?0.35-micron CMOS for optimum speed/power

鈥?High-speed clock to data access 6.5

[1]

/7.5/9/12 ns

(max.)

鈥?Low operating power

鈥?Active = 200 mA (typical)

鈥?Standby = 0.05 mA (typical)

鈥?Fully synchronous interface for easier operation

鈥?Burst counters increment addresses internally

鈥?Shorten cycle times

鈥?Minimize bus noise

鈥?/div>

鈥?Supported in Flow-Through and Pipelined modes

Dual Chip Enables for easy depth expansion

Upper and lower byte controls for bus matching

Automatic power-down

Commercial and Industrial temperature ranges

Available in 100-pin TQFP
