25LC080DT-E/MS

Overview

The Microchip Technology 25LC080DT-E/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible serial bus. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz. The device features a 32-byte page size, automotive temperature range (-40°C to +125°C), and MSOP-8 packaging.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via WP pin and software block protection
• Features built-in power-on/off data protection circuitry
• Provides hold functionality to pause serial transmission without resetting the sequence

Applications

• Microcontroller system data storage
• Industrial control applications
• Automotive electronic modules

Procurement Notes

Verify the specific suffix 'DT' indicates the 32-byte page size variant and 'E' confirms the extended automotive temperature rating. Confirm the 'MS' package designation matches the required MSOP-8 footprint for PCB layout compatibility before finalizing procurement orders.

Selection Notes

Select this component when an SPI EEPROM requires automotive-grade reliability and extended temperature operation. Ensure the design accommodates the 32-byte page write limit and utilizes the HOLD pin if bus arbitration or interrupt handling is necessary during memory access sequences.

Part Context

This part belongs to the 25LC080C/D family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. It shares core architecture with industrial variants but is distinguished by its extended temperature range and specific page size configuration suitable for robust embedded environments.

Replacement Considerations

Direct substitutes include other 25LC080D variants in different packages such as 25LC080D-I/ST or 25LC080D-E/SN, provided the package type and temperature grade requirements are met.
