24LCS52T/SN

Memory IC Overview

The Microchip Technology 24LCS52T/SN is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire interface. It operates within a supply voltage range of 2.2V to 5.5V and supports clock frequencies up to 400 kHz. The device features industrial temperature ratings from -40°C to +85°C, housed in an 8-lead SOIC package with surface mount installation.

Memory IC Feature Summary

• Hardware write protection for the entire array via the WP pin
• Software write protection for the lower half of the memory array
• Schmitt trigger inputs for noise suppression on data lines

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Low-power applications operating on single supply voltages

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the SOIC-8 package type as documented in the official datasheet. Confirm the 'I' designation indicates the Industrial temperature range (-40°C to +85°C). Ensure compatibility with the required I²C bus voltage levels before integration into the design.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application requirements. The 400 kHz clock speed offers faster data transfer compared to standard 100 kHz variants. The inclusion of both hardware and software write protection mechanisms provides flexible data security options for critical system parameters.

Memory IC Part Context

This part belongs to the 24XXX52 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA52 but differs in operational voltage and speed specifications. The family supports multiple package types including PDIP, TSSOP, MSOP, DFN, and TDFN.

Memory IC Replacement Considerations

The 24LC52T-I/SN serves as a direct replacement within the same product family, offering identical functionality and pinout compatibility.
