25LC080DT-E/MNY

Overview

The Microchip Technology 25LC080DT-E/MNY 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 utilizes a TDFN-8 package and features a 32-byte page size. It offers high reliability with over 1 million erase/write cycles, data retention exceeding 200 years, and ESD protection greater than 4000V. Operating temperatures extend from -40°C to +125°C.

Feature Summary

• Supports sequential read operations and self-timed erase/write cycles with a maximum duration of 5 ms.
• Includes built-in write protection mechanisms such as power-on/off data protection, a write enable latch, and a dedicated write-protect pin.
• Features programmable block write protection allowing selection of none, one-quarter, one-half, or all array segments.
• Provides a hold function to pause serial communication without resetting the sequence, facilitating higher priority interrupt servicing.

Applications

• Microcontroller systems requiring non-volatile data storage for configuration parameters
• Industrial control applications needing reliable memory in extended temperature environments
• Automotive electronics utilizing automotive-grade components for critical data logging

Procurement Notes

Verify the specific suffix 'DT-E/MNY' corresponds to the Automotive grade (-E) and TDFN-8 package (MN). Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering quantity matches the reel packaging specifications provided by the distributor. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the intended design requirements.

Selection Notes

Select this component when an SPI interface is required for 8 Kbit non-volatile storage in automotive or industrial sectors. The Automotive grade ensures operation up to 125°C, distinguishing it from Industrial grade variants limited to 85°C. The TDFN-8 package is suitable for space-constrained surface-mount designs. Verify that the 32-byte page size aligns with the application's write efficiency needs compared to 16-byte alternatives.

Part Context

This part belongs to the 25LC080C/D family of 8 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'D' designation indicates a 32-byte page size, while 'C' denotes a 16-byte page size. The 'E' suffix specifies the Automotive temperature range, contrasting with the 'I' suffix for Industrial range. The 'MN' suffix identifies the 8-lead TDFN package type.

Replacement Considerations

Direct substitutes include other 25LC080 variants with different packages or temperature grades, such as 25LC080D-I/ST or 25LC080D-E/SN. Ensure compatibility regarding page size and operating voltage ranges before substitution.
