25LC010AT-H/SN

Overview

The Microchip Technology 25LC010AT-H/SN is a 1 Kbit (128 x 8) Serial Electrically Erasable PROM utilizing SPI-compatible architecture. It operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 5 MHz. The device features an extended temperature range from -40°C to +150°C, housed in an 8-lead SOIC package.

Feature Summary

• Supports byte and page-level write operations with self-timed erase cycles.
• Includes hardware write protection via the WP pin and software block protection.
• Features power-on/off data protection circuitry and a write enable latch.

Applications

• Microcontroller system configuration storage
• Calibration parameter retention
• Embedded device identification

Procurement Notes

Verify the specific suffix 'H' confirms the extended temperature grade (-40°C to +150°C). Confirm the 'T' indicates tape-and-reel packaging if required for automated assembly. Ensure the 'SN' designation matches the 8-lead SOIC footprint requirements for your PCB layout.

Selection Notes

Select this component when high-temperature reliability is critical, as it supports operation up to +150°C. It is suitable for applications requiring low-power CMOS technology and robust ESD protection exceeding 4000V. Verify that the 5 MHz speed meets the system's SPI bus timing constraints.

Part Context

This part belongs to the 25LCXXXA family of low-density serial EEPROMs designed for direct interface with SPI ports. It provides non-volatile memory solutions for embedded systems requiring reliable data retention over extended industrial or automotive operating conditions.

Replacement Considerations

Compatible substitutes include other 25LC010 variants such as 25LC010A-I/SN for standard temperature ranges. Cross-reference datasheet DS22136B for electrical compatibility before substitution.
