25LC010A-H/SN

Overview

The Microchip Technology 25LC010A-H/SN is a 1 Kbit (128 x 8) Serial Electrically Erasable PROM (EEPROM). It supports SPI compatible serial bus architecture with a maximum clock frequency of 5 MHz. The device operates within a supply voltage range of 2.5V to 5.5V and features an extended temperature range from -40°C to +150°C. It is housed in an 8-lead SOIC package.

Feature Summary

• Supports byte and page-level write operations with self-timed erase and write cycles.
• Includes built-in write protection mechanisms such as power-on/off data protection, a write enable latch, and a dedicated write-protect pin.
• Features block write protection allowing selection of none, 1/4, 1/2, or all array segments for protection.

Applications

• Data storage in industrial environments requiring extended temperature operation
• Configuration memory for microcontrollers operating at high temperatures
• Non-volatile parameter storage in automotive or aerospace systems

Procurement Notes

Verify the specific suffix 'H' indicates the extended temperature grade (-40°C to +150°C) and 'SN' denotes the 8-lead SOIC package. Confirm RoHS compliance and Pb-free status against current manufacturer documentation. Ensure the application design accounts for the 6 ms maximum internal write cycle time when implementing write sequences.

Selection Notes

Select this component when high-temperature reliability is required alongside low-density non-volatile storage. The 1 Kbit capacity suits applications needing minimal configuration retention. Verify that the system voltage remains within the 2.5V to 5.5V range to ensure proper operation of the SPI interface and internal high-voltage generator.

Part Context

This part belongs to the 25LCXXXA family of low-density serial EEPROMs designed for direct interface with SPI ports. The 'H' suffix specifically differentiates it from standard commercial grade parts by offering an extended temperature range suitable for harsher operational conditions.

Replacement Considerations

Direct replacements include other 25LC010A variants with matching temperature grades and packages, such as 25LC010A-E/SN, provided the temperature requirements align with the application environment.
