CY7C09269V/79V/89V

CY7C09369V/79V/89V

3.3V 16K/32K/64K x 16/18

Synchronous Dual-Port Static RAM

• High-speed clock to data access 6.5^{[1, 2]}/7.5^[2]/9/12 ns

(max.)

Features

• True Dual-Ported memory cells which allow simulta-

neous access of the same memory location

• 3.3V low operating power

—Active = 115 mA (typical)

• 6 Flow-Through/Pipelined devices

— 16K x 16/18 organization (CY7C09269V/369V)

— 32K x 16/18 organization (CY7C09279V/379V)

— 64K x 16/18 organization (CY7C09289V/389V)

• 3 Modes

—Standby = 10 µA (typical)

• Fully synchronous interface for easier operation

• Burst counters increment addresses internally

—Shorten cycle times

—Minimize bus noise

— Flow-Through

—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

— Pipelined

— Burst

• Pipelined output mode on both ports allows fast

100-MHz operation

• 0.35-micron CMOS for optimum speed/power
