16K x 16 Dual-Port RAM w/Int

The 70261 is a high-speed 16K x 16 Dual-Port Static RAM designed to be used as a stand-alone Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. An automatic power down feature controlled by CE permits the on-chip circuitry of each port to enter a very low standby power mode.

Features

  • True Dual-Ported memory cells which allow simultaneous
  • access of the same memory location
  • Separate upper-byte and lower-byte control for multiplexed bus compatibility
  • 70261 easily expands data bus width to 32 bits or more
  • Busy and Interrupt Flags
  • On-chip port arbitration logic
  • Full on-chip hardware support of semaphore signaling between ports
  • Fully asynchronous operation from either port
  • TTL-compatible, single 5V (±10%) power supply
  • Available in 100-pin TQFP package
  • Industrial temperature range (-40OC to +85OC) is available
