7027

32K x 16 Dual-Port RAM

The 7027 is a high-speed 32K x 16 Dual-Port Static RAM designed to be used as a stand-alone 512K-bit Dual-Port RAM or as a combination MASTER/SLAVE Dual-Port RAM for 32-bit-or-more word systems. An automatic power down feature permits the on-chip circuitry of each port to enter a very low standby power mode. Military grade product in compliance with MIL-PRF-38535 QML is available.

Features

  • True Dual-Ported memory cells which allow simultaneous
  • access of the same memory location
  • Separate upper-byte and lower-byte control for bus matching capability.
  • Dual chip enables allow for depth expansion without external logic
  • 7027 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 and 108-pin PGA packages
  • Industrial temperature range (–40C to +85C) is available
