Overview
The Microchip Technology 27LV512-20/L089 is a low-voltage, CMOS 512K (64K x 8) EPROM. It operates with a single 2.7V to 3.6V power supply and features fast access times of 20ns. The device utilizes standard SRAM-compatible outputs for high-speed performance while maintaining low power consumption in active and standby modes. It includes an output enable pin for bus control and is housed in a 28-pin plastic DIP package.
Feature Summary
- Low voltage operation compatible with 3.3V systems
- Fast 20ns access time for high-speed applications
- CMOS technology ensures low power consumption
- Standard SRAM-compatible output interface
Applications
- Embedded system memory storage
- Industrial control systems
- Telecommunications equipment
- Consumer electronics firmware storage
Procurement Notes
Verify the specific suffix 'L089' against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing board layouts requiring 28-pin DIP form factors. Check for obsolescence status or lifecycle notices on the manufacturer's website before procurement planning.
Selection Notes
Select this component when a non-volatile memory solution is required for 64K x 8 data storage with low voltage constraints. It is suitable for designs needing fast read access without the complexity of flash programming interfaces. Consider thermal requirements and package availability for manufacturing scalability.
Part Context
This part belongs to the 27LV series of EPROMs from Microchip, designed as drop-in replacements for older NMOS EPROMs. The series emphasizes reduced power consumption and lower operating voltages compared to traditional 5V devices, making it ideal for modern portable and battery-operated applications.
Replacement Considerations
Check Microchip's official cross-reference tools for direct equivalents. Verify that any substitute maintains the same 28-pin DIP package and 20ns speed grade. Ensure voltage compatibility and pinout alignment to avoid redesign efforts.
