PRELIMINARY

CY7C09269/79/89

CY7C09369/79/89

16K/32K/64K x16/18

Synchronous Dual Port Static RAM

Features

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• 6 Flow-Through/Pipelined devices

— 16K x 16/18 organization (CY7C09269/369)

— 32K x 16/18 organization (CY7C09279/379)

— 64K x 16/18 organization (CY7C09289/389)

• 3 Modes

— Flow-Through

— Pipelined

— Burst

• Pipelined output mode on both ports allows fast

100-MHz cycle time

• 0.35-micron CMOS for optimum speed/power

• High-speed clock to data access 6.5/7.5/9/12 ns (max.)

• Low operating power

— Active= 195 mA (typical)

— Standby= 0.05 mA (typical)

• Fully synchronous interface for easier operation

• Burst counters increment addresses internally

— Shorten cycle times

— Minimize bus noise

•

— 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

Pin-compatible and functionally equivalent to

IDT709269, IDT70927, and IDT709279
