特性
- 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
- Separate upper-byte and lower-byte controls for multiplexed bus and bus matching compatibility
- TTL- compatible, single 5V (±10%) power supply
- Available in a 100-pin TQFP package
- Industrial temperature range (–40C to +85C) is available
描述
The 709279 is a high-speed 32K 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.
