特長
- 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
説明
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.
