PRELIMINARY
CY7C09349A
CY7C09359A
4K/8K x 18
Synchronous Dual-Port Static RAM
High-speed clock to data access 6.5
[1]
/7.5/9/12 ns (max.)
Low operating power
—Active = 200 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

Features
True dual-ported memory cells which allow simulta-
neous access of the same memory location
Two Flow-Through/Pipelined devices
—4K x 18 organization (CY7C09349A)
—8K x 18 organization (CY7C09359A)
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
