CY7C09179V/89V/99V

3.3V 32K/64K/128K x 8/9

Synchronous Dual-Port Static RAM

• High-speed clock to data access 6.5^[1]/7.5^[1]/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

— 32K x 8/9 organizations (CY7C09079V/179V)

— 64K x 8/9 organizations (CY7C09089V/189V)

— 128K x 8/9 organizations (CY7C09099V/199V)

• 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

• Automatic power-down

— Pipelined

— Burst

• Pipelined output mode on both ports allows fast

100-MHz operation

• Commercial and Industrial temperature ranges

• Available in 100-pin TQFP

• 0.35-micron CMOS for optimum speed/power

• Pb-Free packages available
