... The NV SRAM can be used in place of existing SRAMs directly conforming to the popular bytewide 28-pin DIP standard. The DS1225Y also matches the pinout of the 2764 EPROM or the 2864 EEPROM, allowing direct substitution while enhancing performance. There is no limit on the number of write cycles that can be executed and no additional support circuitry is required for micro- processor interfacing ...

... OE WRITE MODE The DS1225Y executes a write cycle whenever the WE and CE signals are active (low) after address inputs are stable. The later-occurring falling edge will determine the start of the write cycle. The write cycle is terminated by the earlier rising edge All address inputs must be kept valid throughout the write cycle ...
