25LC010AT-E/SN16KVAO

Overview

The Microchip Technology 25LC010AT-E/SN 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. The device operates within a supply voltage range of 2.5V to 5.5V and supports page write modes up to 16 bytes. It includes self-timed erase and write cycles with a maximum duration of 5 ms, ensuring high reliability through 1,000,000 erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports sequential read operations and page write modes for efficient data handling
• Includes built-in hardware write protection via the WP pin and software block protection
• Features power-on/off data protection circuitry and a write enable latch mechanism

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage in industrial equipment

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and the 'SN' indicates the SOIC package. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering code aligns with the required lead times and packaging options available from authorized distributors.

Selection Notes

Select this component when an SPI interface is required for non-volatile storage in automotive or industrial environments. The 1 Kbit capacity suits applications needing small data retention. Verify that the 2.5V minimum operating voltage meets the system's power supply constraints and that the 10 MHz clock speed is compatible with the host controller.

Part Context

This part belongs to the 25LC010A family of 1 Kbit EEPROMs. The 'E' suffix denotes the extended temperature range suitable for automotive applications. It shares functional similarities with the 25AA010A but differs in its lower minimum operating voltage requirement of 2.5V compared to the 1.8V support of the AA variant.

Replacement Considerations

The 25LC010AT-I/SN serves as a direct replacement if the application does not require the extended -40°C to +125°C temperature range specified by the 'E' suffix. Both parts share identical electrical characteristics and pinouts within their respective operational limits.
