PRELIMINARY
32K/64K/128K x 8/9
Synchronous Dual-Port Static RAM
High-speed clock to data access 6.5
[1]
/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
Automatic power-down
Commercial and Industrial temperature ranges
Available in 100-pin TQFP
Pin-compatible and functionally equivalent to
IDT709079, IDT70908, and IDT709089

Features
True dual-ported memory cells which allow simulta-
neous access of the same memory location
Six Flow-Through/Pipelined devices
—32K x 8/9 organizations (CY7C09079/179)
—64K x 8/9 organizations (CY7C09089/189)
—128K x 8/9 organizations (CY7C09099/199)
Three 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
