PRELIMINARY
16K/32K/64K x16/18
Synchronous Dual Port Static RAM
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

Features
True dual-ported memory cells which allow simulta-
neous access of the same memory location
Six 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)
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
High-speed clock to data access 6.5
