The Microchip Technology 27LV256 is a low voltage (3.0 volt) CMOS EPROM designed for battery powered applications. The device is organized as a 32K x 8 (32K-Byte) non-volatile memory product. The 27LV256 consumes only 8 mA 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 (chip enable pin going low) is accomplished in less than 200 ns at 3.0V. This device allows systems designers the ability to use low voltage non-volatile memory with today’s' low voltage microprocessors and peripherals in battery powered applications.

A complete family of packages is offered to provide the most flexibility in applications. For surface mount applications, PLCC or SOIC packaging is available. Tape and reel packaging is also available for PLCC or SOIC packages.
