25LC1024T-E/SM16KVAO

Overview

The Microchip Technology 25LC1024T-E/SM16KVAO is a 1-Mbit (128K x 8) serial EEPROM utilizing an SPI-compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 20 MHz at higher voltages or 10 MHz at lower voltages. The device features a 256-byte page size, 1 million erase/write cycle endurance, and data retention exceeding 200 years. It is housed in an 8-lead SOIJ package and qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Supports byte and page-level write operations with self-timed erase cycles
• Includes sector write protection capabilities for specific memory segments
• Features built-in power-on/off data protection and write enable latch mechanisms

Applications

• Automotive electronic systems requiring AEC-Q100 qualification
• Industrial control units needing high reliability and extended temperature operation
• Embedded microcontroller systems storing configuration parameters via SPI bus

Procurement Notes

Verify the specific 'E' suffix indicates the extended temperature range (-40°C to +125°C) compared to industrial variants. Confirm the '16KVAO' ordering suffix matches the required reel packaging specifications. Ensure the SOIJ package type aligns with the target PCB footprint design before finalizing procurement orders.

Selection Notes

Select this component when high-speed SPI communication up to 20 MHz is required alongside robust automotive-grade reliability. The extended temperature rating makes it suitable for harsh environments where standard industrial parts may fail. Consider the 256-byte page size for efficient bulk data writing operations.

Part Context

This part belongs to the 25LC1024 family of 1-Mbit serial EEPROMs from Microchip Technology. It shares core architectural similarities with other density levels in the series but offers specific performance characteristics tailored for high-reliability applications. The SOIJ package provides a compact surface-mount solution for space-constrained designs.

Replacement Considerations

Direct replacements include the 25LC1024-I/SM for industrial temperature ranges or the 25LC1024T-E/MF if a DFN-S package is preferred. Verify pin compatibility and software instruction set adherence when substituting across different package types within the same memory density family.
