25LC010AT-E/MNY

Overview

The Microchip Technology 25LC010AT-E/MNY is a 1 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) utilizing an SPI-compatible serial bus. It features a 128 x 8-bit organization with a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 2.5V to 5.5V and supports an industrial temperature range of -40°C to +125°C. It is housed in an 8-lead TDFN package.

Feature Summary

• Supports write page mode for up to 16 bytes and sequential read operations
• Includes built-in write protection via power-on/off data protection circuitry, write enable latch, and dedicated write-protect pin
• Features block write protection allowing selection of none, 1/4, 1/2, or all array segments

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and SPI interface requirements before procurement. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and current availability status.

Selection Notes

Select this component for applications requiring non-volatile memory with hardware-level write protection capabilities. Consider the automotive temperature grade (-40°C to +125°C) for harsh environments. Evaluate the 10 MHz clock speed and low standby current against system power and performance constraints.

Part Context

This EEPROM belongs to the 25XX010A family, which includes variants like the 25AA010A. The 'E' suffix denotes an extended temperature range suitable for automotive applications, while 'MNY' indicates the specific TDFN package configuration. It interfaces directly with SPI ports common in modern microcontroller families.

Replacement Considerations

Consult official datasheets for cross-referencing with other 1Kbit SPI EEPROMs from Microchip or competitors. Verify pinout compatibility and electrical characteristics such as voltage ranges and clock speeds before substituting.
