1 / 10 page  2004 Microchip Technology Inc. DS11024F-page 1 27LV64 FEATURES • Wide voltage range 3.0V to 5.5V • High speed performance - 200 ns access time available at 3.0V • CMOS Technology for low power consumption - 8 mA active current at 3.0V - 20 mA active current at 5.5V - 100 µA standby current • Factory programming available • Auto-insertion-compatible plastic packages • Auto ID aids automated programming • Separate chip enable and output enable controls • High speed “express” programming algorithm • Organized 8K x 8: JEDEC standard pinouts - 28-pin Dual-in-line package - 32-pin PLCC Package - 28-pin SOIC package - Tape and reel • Available for the following temperature ranges: - Commercial: 0°C to +70°C - Industrial: -40°C to +85°C DESCRIPTION The Microchip Technology Inc. 27LV64 is a low-voltage (3.0 volt) CMOS EPROM designed for battery powered applications. The device is organized as 8K x 8 (8K- Byte) non-volatile memory product. The 27LV64 con- sumes only 8mA maximum of active current during a 3.0 volt read operation therefore improving battery per- formance. 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 system 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.
