- 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 68-pin PGA and PLCC, and 80-pin TQFP packages
- Industrial temperature range (-40 °C to +85 °C) is available
描述
The 70V07 is a high-speed 32K x 8 dual-port static RAM designed to be used as a stand-alone 256K-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 Chip Enable (CE) permits the on-chip circuitry of each port to enter a very low standby power mode.
