The device is organized as 8K x 8 (8KByte) non-volatile memory product. The 27LV64 consumes only 8mA maximum of active current during a 3.0 volt read operation therefore improving battery performance. This device is designed for very low voltage applications where conventional 5.0 volt only EPROMs can not be used. Accessing individual bytes from an address transition or from power-up (ch...
