24LC025T-E/SN

Memory IC Overview

The Microchip Technology 24LC025T-E/SN is a 2 Kbit (256 x 8) serial EEPROM utilizing an I2C-compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features low-power CMOS technology with typical standby current of 1 μA and read current of 1 mA. It includes a 16-byte page write buffer, hardware write protection capabilities via the WP pin, and Schmitt trigger inputs for noise suppression. The component is housed in an 8-lead TSSOP package and is rated for automotive temperature ranges.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial bus protocol compatible with standard I2C operations.
• Features a 16-byte page write buffer that allows efficient storage of multiple bytes before initiating an internal write cycle.
• Includes Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce during operation.

Memory IC Applications

• Contiguous memory expansion across multiple devices on a shared serial bus
• Storage of configuration parameters and calibration data in embedded systems
• Data logging applications requiring non-volatile retention

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the Automotive grade (-40°C to +125°C) and 'SN' denotes the 8-SOIC package, as datasheet tables list 'I' for Industrial and 'E' for Automotive grades. Confirm the ordering suffix matches the required temperature range and physical footprint. Ensure the source document explicitly links the full part number to these specifications.

Memory IC Selection Notes

Select this component when an application requires non-volatile storage with I2C connectivity and robust noise immunity. The inclusion of Schmitt triggers makes it suitable for electrically noisy environments. Consider the 16-byte page buffer for write efficiency and verify that the 2.5V minimum supply voltage aligns with the system power rails.

Memory IC Part Context

This device belongs to the 24AA024/24LC024/24AA025/24LC025 family of 2 Kbit Serial Electrically Erasable PROMs. The family shares common architectural features such as the 2-wire interface and low-power design, but varies in voltage ranges and temperature grades. The 24LC series specifically targets applications requiring a 2.5V minimum operating voltage.
