Description
The CY7C138 and CY7C139 are high-speed CMOS 4K x 8 and 4K x 9 dual-port static RAMs.
Features
- True Dual-Ported memory cells that allow simultaneous reads of the same memory location.
- 4K x 8 organization (CY7C138).
- 4K x 9 organization (CY7C139).
- 0.65-micron CMOS for optimum speed/power.
- High-speed access: 15 ns.
- Low operating power: ICC = 160 mA (max. ).
- Fully asynchronous operation.
- Automatic power-down.
- TTL compatible.
- Expandable data bus to 32/36 bits or more using
Master/Slave chip select when us.
