The Microchip Technology Inc. 27LV256 is a low volt-  
age (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 cur-  
rent during a 3.0 volt read operation therefore improv-  
ing battery performance. This device is designed for  
very low voltage applications where conventional 5.0  
volt only EPROMS can not be used. Accessing individ-  
ual 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 appli-  
cations, PLCC or SOIC packaging is available. Tape  
and reel packaging is also available for PLCC or SOIC  
packages.
