3.3V 16K/32K/64K x 16/18
Synchronous Dual-Port Static RAM
Features
⢠True Dual-Ported memory cells which allow simulta-
neous access of the same memory location
⢠6 Flow-Through/Pipelined devices
â 16K x 16/18 organization (CY7C09269V/369V)
â 32K x 16/18 organization (CY7C09279V/379V)
â 64K x 16/18 organization (CY7C09289V/389V)
⢠3 Modes

(max.)
⢠3.3V low operating power
â Active = 115 mA (typical)
â Standby = 10 µA (typical)
⢠Fully synchronous interface for easier operation
⢠Burst counters increment addresses internally
â Shorten cycle times
â Minimize bus noise
â 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
⢠Pb-Free 100-pin TQFP Package Available
