特性

  • True dual-ported memory cells, which allow 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
  • Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility
  • LVTTL- compatible, single 3.3V (±0.3V) power supply
  • Available in 128-pin and 100-pin TQFP packages
  • Industrial temperature range (–40°C to +85°C) is available

描述

The 70V9289 is a high-speed 64K x 16-bit synchronous dual-port RAM that 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.
