Overview
The Microchip Technology 25LC080A-H/SN is an 8 Kbit (1K x 8) Serial Electrically Erasable PROM featuring SPI-compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 10 MHz. The device utilizes an 8-pin SOIC package with surface mount installation. Key electrical parameters include a maximum access time of 50 ns, active read current of 6 mA, and data retention of 200 years. It functions across an industrial temperature range of -40°C to +125°C.
Feature Summary
- Supports high-speed serial communication via SPI bus with separate data in and out lines
- Provides non-volatile memory storage with long-term data retention capabilities
- Includes hardware write protection for secure data integrity
Applications
- Industrial control systems requiring reliable data logging
- Automotive electronics operating in harsh thermal environments
- Consumer devices needing compact non-volatile configuration storage
Procurement Notes
Verify the specific suffix H against official datasheets to confirm extended temperature ratings and automotive qualification status. Ensure compatibility with system voltage levels between 2.5V and 5.5V. Confirm package dimensions match the 8-SOIC specification. Check for RoHS compliance documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when SPI interface simplicity and wide operating voltage are required. Compare against 25LC080 variants for temperature grade differences. Consider pinout compatibility with existing PCB layouts. Evaluate power consumption requirements against the 6 mA active read current specification.
Part Context
This part belongs to the 25XX080 family of 8 Kbit Serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25LC080 and 25AA080 series but differs in voltage ranges and temperature specifications. The family is designed for applications requiring small footprint memory solutions with standard serial interfaces.
Replacement Considerations
Public confirmed substitutes include 25LC080A-I/SN and 25LC080A-E/SN. Verify functional equivalence regarding voltage ranges and temperature specifications before substitution.
