The µPD4482161 is a 524,288-word by 16-bit, the µPD4482181 is a 524,288-word by 18-bit, the µPD4482321 is a 262,144-word by 32-bit and the µPD4482361.
Features
* 3.3 V or 2.5 V core supply
* Synchronous operation
* Operating temperature : TA = 0 to 70 °C (-A65, -A75, -A85, -C75, -C85) TA =
* 40 to +85 °C (-A65Y, -A75Y, -A85Y, -C75Y, -C85Y)
* Internally self-timed write control
* Burst read / write : Interleave
Applications
* which require synchronous operation, high speed, low voltage, high density and wide bit configuration, such as cache and buffer memory. ZZ has to be set LOW at the normal operation. When ZZ is set HIGH, the SRAM enters Power Down State (“Sleep”). In the “Sleep” state, the SRAM internal state is pres
