70V09L20PFGI General Description

The 70V09 is a high-speed 128K x 8 Dual-Port Static RAM designed to be used as a stand-alone 1024K-bit Dual-Port SRAM or as a combination MASTER/SLAVE Dual-Port SRAM for 16-bit-or-more word systems which results in full speed, error-free operation without the need for additional discrete logic. An automatic power down feature controlled by the chip enables (either CE0 or CE1) permit the on-chip circuitry of each port to enter a very low standby power mode.

Key Features

True Dual-Ported memory cells which allow simultaneous reads of the same memory location
70V09 easily expands data bus width to 16 bits or more
Dual chip enables allow for depth expansion without external logic
Busy and Interrupt Flag
On-chip port arbitration logic
Full on-chip hardware support of semaphore signaling between ports
Fully asynchronous operation from either port
TTL-compatible, single 3.3V (±0.3V) power supply
Available in 100-pin TQFP packages
Industrial temperature range (-40C to +85C) is available
