25LC010AT-E/MC

Overview

The Microchip Technology 25LC010AT-E/MC is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It utilizes an SPI-compatible serial bus for communication, supporting a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 2.5 V to 5.5 V and features automotive temperature ratings from -40°C to +125°C. Key electrical characteristics include a standby current of 5 µA at 5.5 V and write currents up to 5 mA. It offers high reliability with 1,000,000 erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports sequential read operations and page write modes accommodating up to 16 bytes per cycle.
• Includes hardware write protection via the WP pin and software block protection through the STATUS register.
• Features built-in power-on/off data protection circuitry and a write enable latch mechanism.
• Provides a HOLD input to pause serial communication without resetting the sequence.

Applications

• Automotive electronic systems requiring extended temperature operation
• Industrial control devices needing non-volatile configuration storage
• Embedded microcontroller applications utilizing SPI interfaces

Procurement Notes

Verify the specific suffix 'MC' against official Microchip documentation to confirm package type and availability. Ensure the automotive grade 'E' designation matches the required operating temperature range for your application. Confirm RoHS compliance status and lead-free specifications prior to ordering.

Selection Notes

Select this component when an SPI EEPROM with automotive temperature qualification (-40°C to +125°C) is required. The 2.5 V minimum supply voltage distinguishes it from lower-voltage variants. Consider the 16-byte page size for write efficiency and the available block protection options for security requirements.

Part Context

This part belongs to the 25LC010A family of 1 Kbit SPI EEPROMs manufactured by Microchip Technology. The 'E' suffix indicates automotive temperature grading, while 'MC' denotes the specific package variant. It shares functional compatibility with other members of the 25XX010A series regarding instruction sets and timing.
