24LC025T/ST

Memory IC Overview

The Microchip Technology 24LC025T/ST is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire 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 a 16-byte page write buffer, hardware write protection capabilities via the WP pin, and Schmitt trigger inputs for noise suppression. It offers high endurance exceeding one million erase/write cycles and data retention of over 200 years.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using hardware address pins A0, A1, and A2.
• Includes output slope control circuitry designed to eliminate ground bounce during operation.
• Features internal self-timed erase/write cycles with automatic acknowledge polling support.

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Smart metering applications

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the presence of the Write Protect (WP) pin functionality if hardware protection is necessary for the design. Ensure the power supply voltage remains within the specified 2.5V to 5.5V range to maintain proper device operation and timing specifications.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application requirements. Choose this part over the 24AA025 variant if the system requires a minimum operating voltage of 2.5V rather than 1.7V. Verify that the TSSOP-8 package dimensions fit the available PCB space constraints.

Memory IC Part Context

This device belongs to the 24LC025 family of serial electrically erasable PROMs. It shares functional similarities with the 24AA025 but differs in its minimum operating voltage specification. The 'T' suffix indicates tape and reel packaging, while '/ST' denotes the 8-lead TSSOP package format suitable for surface mount assembly.

Memory IC Replacement Considerations

The 24LC025T-I/ST is a verified industrial-grade replacement offering identical electrical characteristics and pinout compatibility within the same temperature range.
