25LC080DT-E/SN

Overview

The Microchip Technology 25LC080DT-E/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It operates via a SPI-compatible serial bus with a maximum clock frequency of 10 MHz at VCC levels between 4.5V and 5.5V. The device supports a 32-byte page size and utilizes automotive-grade components rated for temperatures from -40°C to +125°C. Power supply requirements range from 2.5V to 5.5V, with standby current as low as 1 µA. It includes hardware write protection and self-timed erase/write cycles.

Feature Summary

• Supports high-speed SPI communication with hold functionality for interrupt servicing
• Includes block write protection and power-on data protection circuitry
• Features self-timed erase and write cycles with internal write enable latch

Applications

• Microcontroller system data storage
• Industrial control parameter logging
• Automotive electronic configuration memory

Procurement Notes

Verify the specific suffix 'DT' indicates the TDFN package and 'E' denotes the extended temperature grade. Confirm the 'D' variant specifies the 32-byte page size rather than the 16-byte page found in 'C' versions. Ensure the source documentation explicitly lists this exact part number to avoid confusion with similar industrial or alternative package variants within the same family.

Selection Notes

Select this component when automotive temperature ratings are required alongside standard SPI EEPROM functionality. The 32-byte page size offers efficiency for larger data blocks compared to 16-byte alternatives. Verify that the host microcontroller supports the necessary SPI modes and voltage levels compatible with the 2.5V to 5.5V operating range.

Part Context

This part belongs to the 25LC080C/D series of 8K SPI Bus Serial EEPROMs. It shares functional similarities with other members like the 25LC080D-E/SN but differs in packaging and temperature rating. The 'DT' suffix specifically identifies the 2x3 TDFN package type, distinguishing it from SOIC, MSOP, or PDIP options available in the broader product line.
