25LC080AT-H/SN

Overview

The Microchip Technology 25LC080AT-H/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1K x 8 organization. It operates via an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 2.5 V to 5.5 V and utilizes an 8-SOIC package (3.90 mm width). It offers a data retention period of 200 years and functions within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Supports high-speed SPI communication with a 10 MHz clock rate
• Provides long-term non-volatile data retention for critical storage
• Operates across a wide industrial temperature range for harsh environments

Applications

• Industrial control systems requiring reliable parameter storage
• Consumer electronics needing configuration data preservation
• Automotive modules operating in extreme thermal conditions

Procurement Notes

Verify the specific suffix 'H' indicates the extended temperature grade (+125°C) against the official datasheet, as standard variants may differ. Confirm the 'T' suffix denotes tape-and-reel packaging suitable for automated assembly. Ensure compatibility with existing PCB footprints for the 8-SOIC package before finalizing procurement orders.

Selection Notes

Select this component when both high-speed access and extended temperature resilience are required. Compare against the 25LC080A series if lower cost or different packaging is acceptable. Verify that the 2.5V minimum supply voltage aligns with the system power rails, as some legacy EEPROMs support lower voltages.

Part Context

This part belongs to the Microchip 25XX080 family of 8-Kbit Serial EEPROMs. It shares architectural similarities with the 25LC080A and 25LC080D models but distinguishes itself through the extended temperature rating indicated by the 'H' suffix. The family utilizes a common SPI interface for simplified integration into microcontroller-based designs.

Replacement Considerations

Publicly confirmed substitutes include other 25LC080 variants from Microchip with matching pinouts and electrical characteristics. Cross-reference the temperature grade and package dimensions to ensure mechanical fit. Verify that alternative sources maintain the same 10 MHz clock speed specification.
