25LC010AT-I/MNY

Overview

The Microchip Technology 25LC010AT-I/MNY is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates on an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 2.5V to 5.5V and functions within an industrial temperature range of -40°C to +85°C. It utilizes an 8-lead TDFN package.

Feature Summary

• Supports write page mode for up to 16 bytes per cycle
• Includes block write protection for selective array security
• Features built-in power-on/off data protection circuitry
• Provides sequential read capability with automatic address pointer increment

Applications

• Microcontroller system configuration storage
• Calibration data retention in embedded devices
• Parameter logging in industrial sensors
• Firmware version tracking in IoT modules

Procurement Notes

Verify the specific suffix 'I/MNY' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 8-lead TDFN package format. Confirm RoHS compliance status and lead-free material specifications against the manufacturer's current datasheet revision DS21832H before finalizing procurement orders.

Selection Notes

Select this component when a small, non-volatile memory solution is required for storing calibration constants or user settings. Ensure the host microcontroller supports SPI communication at speeds up to 10 MHz. Verify that the system voltage remains within the 2.5V to 5.5V operating range to guarantee reliable data retention and endurance performance.

Part Context

This part belongs to the 25XX010A family of 1 Kbit Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25AA010A but differs in minimum operating voltage requirements. The family offers various package options including SOIC, MSOP, and TDFN to accommodate different PCB layout constraints.

Replacement Considerations

Direct substitutes include other 25LC010A variants with compatible pinouts and electrical characteristics. Verify package compatibility and temperature ratings when considering alternatives from the same manufacturer or cross-brand equivalents.
