25LC010AT-I/MC

Overview

The Microchip Technology 25LC010AT-I/MC 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 and operates within a supply voltage range of 2.5V to 5.5V. The device supports page write modes up to 16 bytes, self-timed erase/write cycles of 5 ms max, and block write protection. It includes built-in power-on/off data protection and is housed in an 8-lead TDFN package.

Feature Summary

• Supports high-speed SPI communication with sequential read capabilities
• Includes hardware write-protect pin and software-based block protection
• Features low-power CMOS technology with standby current reduction
• Provides built-in power-on/off data protection circuitry

Applications

• Embedded systems requiring non-volatile configuration storage
• Microcontroller peripheral memory expansion via SPI interface
• Industrial control applications needing reliable data retention
• Automotive electronics operating within specified temperature ranges

Procurement Notes

Verify the specific suffix 'MC' corresponds to the 8-lead TDFN package type as documented in the official datasheet. Confirm that the 'I' designation matches the required industrial temperature range specifications for your application environment. Ensure compatibility with the 2.5V to 5.5V supply voltage requirements before integration into the system design.

Selection Notes

Select this component when a small capacity EEPROM with SPI interface is required. It is suitable for applications needing moderate speed and robust write protection features. Consider the TDFN package constraints regarding thermal dissipation and board space. Verify that the system voltage aligns with the minimum 2.5V operational requirement for reliable performance.

Part Context

This part belongs to the 25LC010A series of 1 Kbit SPI EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25AA010A but differs in supply voltage requirements. The series is designed for general-purpose non-volatile memory applications where data integrity and simple interface protocols are prioritized over high-density storage.

Replacement Considerations

Direct replacements include other variants within the 25LC010A family such as 25LC010AT-I/SN or 25LC010AT-I/MS, provided the package footprint and electrical characteristics match the design requirements. Cross-referencing with the 25AA010A series is possible if voltage levels are compatible.
