Features
True Dual-Ported memory cells which enable simultaneous
access of the same memory location
6 Flow-Through and 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
Flow-Through
Pipelined
Burst
Pipelined output mode on both ports enables fast 100 MHz
operation
0.35-micron CMOS for optimum speed and power
High speed clock to data access 6.5[1]/7.5[1]/9/12 ns (max.)
3.3V low operating power
Active= 115 mA (typical)
Standby= 10 A (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
Pb-free packages available
Notes
