24LC025T-E/ST

Memory IC Overview

The Microchip Technology 24LC025T-E/ST is a 2 Kbit (256 x 8) serial electrically erasable PROM. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I2C compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features a page write buffer for up to 16 bytes, hardware write protection capabilities, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead TSSOP package and is rated for industrial temperature ranges.

Memory IC Feature Summary

• Supports cascading of up to eight devices on the same bus using hardware address pins
• Includes output slope control to eliminate ground bounce during operation
• Features self-timed erase/write cycles with internal write cycle timing

Memory IC Applications

• Data storage for system configuration parameters
• Storage of calibration data and user-defined settings
• Non-volatile memory for embedded controller applications

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range requirements align with the 2.5V minimum specification for the LC series. Ensure compatibility with the I2C bus protocol and check for any specific lead-free or RoHS compliance documentation required for your manufacturing process.

Memory IC Selection Notes

Select this component when a 2 Kbit non-volatile memory solution is required with I2C interface compatibility. Consider the 8-lead TSSOP package for surface mount applications. Verify that the operating voltage range of 2.5V to 5.5V meets the system power supply constraints. Note that this specific part number does not include hardware write protection, unlike the 24LC024 variant.

Memory IC Part Context

This device belongs to the 24AA024/24LC024/24AA025/24LC025 family of serial EEPROMs. It shares functional similarities with other members of the series but differs in organization and voltage specifications. The 'E' suffix indicates an automotive temperature grade, while the 'I' suffix denotes industrial grade. The 'T' indicates tape and reel packaging.

Memory IC Replacement Considerations

The 24LC025T-I/ST is a direct replacement offering the same electrical characteristics but with an industrial temperature rating instead of automotive.
