70V07 - Block Diagram


32K x 8 3.3V Dual-Port

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 CE permits the on-chip circuitry of each port to enter a very low standby power mode.


  • True Dual-Ported memory cells which allow simultaneous reads of the same memory location
  • 70V07 easily expands data bus width to 16 bits or more
  • 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 (-40C to +85C) is available
