709079 - Block Diagram


32K x 8 Sync, Dual-Port RAM, Pipelined/Flow-Through

The 709079 is a high-speed 32K x 8 bit synchronous Dual- Port RAM. Registers on control, data, and address inputs provide minimal setup and hold times allowing systems to be designed with very short cycle times. With an input data register, it has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode.


  • True Dual-Port allows simultaneous access of the same memory location
  • Flow-Through or Pipelined output mode on either port via the FT/PIPE pin
  • Counter enable and reset features
  • Dual chip enables allow for depth expansion without additional logic
  • Full synchronous operation on both ports
  • TTL- compatible, single 5V (±10%) power supply
  • Available in 100-pin TQFP package
  • Industrial temperature range (–40C to +85C) is available
