24LCS52T-I/ST

Memory IC Overview

The Microchip Technology 24LCS52T-I/ST is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface with a maximum clock frequency of 400 kHz. It operates within a supply voltage range of 2.2 V to 5.5 V and supports industrial temperatures from -40°C to +85°C. The device utilizes an 8-lead TSSOP package and includes hardware write protection via the WP pin, software write protection for the lower half of the array, and a page write buffer for up to 16 bytes.

Memory IC Feature Summary

• Hardware write protection capability for the entire memory array using the dedicated WP pin
• Software-based write protection mechanism that permanently locks the lower half of the memory space
• Integrated page write buffer allowing sequential storage of up to 16 bytes in a single operation

Memory IC Applications

• Industrial control systems requiring non-volatile data retention across wide temperature ranges
• Embedded devices utilizing I²C bus architectures for configuration storage
• Applications necessitating permanent protection of critical lower memory addresses

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' confirms the Industrial temperature grade (-40°C to +85°C) and TSSOP-8 surface mount packaging. Confirm the 'T' designation indicates tape and reel shipping format. Ensure compatibility with the 2.2V minimum operating voltage requirement for the 24LCS52 variant rather than the 1.8V limit found in other series members.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is required alongside strict I²C timing constraints at 400 kHz. The 24LCS52 variant is appropriate for designs needing reliable operation down to 2.2 V. Consider the integrated hardware write protection if system-level security against accidental writes is necessary without relying solely on software commands.

Memory IC Part Context

This part belongs to the 24XXX52 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA52 but differs in electrical specifications, specifically supporting higher clock frequencies at elevated voltages. The family provides standardized I²C communication protocols suitable for various microcontroller-based embedded applications.

Memory IC Replacement Considerations

The 24LC52T-I/ST serves as a functional substitute within the same product family, offering identical memory organization and interface protocols.
