24LCS52T/ST

Memory IC Overview

The Microchip Technology 24LCS52T-I/ST 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 in the industrial temperature range (-40°C to +85°C). The device features a typical active current of 1 mA and standby current of 1 µA, with a maximum write cycle time of 5 ms.

Memory IC Feature Summary

• Hardware write protection via WP pin for entire array
• Software write protection for lower half of memory
• Page write buffer supporting up to 16 bytes
• Schmitt trigger inputs for noise suppression

Memory IC Applications

• Data acquisition systems requiring non-volatile storage
• Personal communications devices
• Industrial control applications

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and '/ST' indicates the TSSOP-8 package. Confirm RoHS compliance status through official manufacturer documentation or datasheet revision history before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is required alongside hardware and software write protection capabilities. Ensure the application environment remains within the specified -40°C to +85°C operating temperature range and utilizes a compatible I²C bus architecture.

Memory IC Part Context

This part belongs to the 24XXX52 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA52 but differs in electrical characteristics, specifically the minimum operating voltage and maximum clock frequency specifications defined for the industrial grade variant.

Memory IC Replacement Considerations

Direct substitutes include other 24LCS52 variants with different packaging options such as MSOP or DFN, provided the pinout and electrical specifications remain identical.
