24LCS52T-I/MS

Memory IC Overview

The Microchip Technology 24LCS52T-I/MS is a 2 Kbit (256 x 8) serial EEPROM utilizing an I2C-compatible 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 a typical access time of 900 ns and a write cycle time of 5 ms. Designed for industrial applications, it functions reliably between -40°C and +85°C. The component is housed in an 8-lead MSOP package.

Memory IC Feature Summary

• Supports hardware write protection via the WP pin to secure the entire memory array
• Includes software write protection capability for the lower half of the memory space
• Integrates Schmitt trigger inputs on data and clock lines for enhanced noise suppression

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Smart metering equipment with moderate memory requirements

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range of -40°C to +85°C. Confirm the '/MS' designation matches the required 8-lead MSOP surface mount package. Ensure the 'T' indicates tape and reel packaging if automated assembly is planned. Cross-reference the manufacturer part number against official Microchip documentation to validate authenticity.

Memory IC Selection Notes

Select this component when an I2C interface is required alongside hardware-level write protection capabilities. It is suitable for designs operating at voltages as low as 2.2V. Consider the 400 kHz speed limit and page write buffer size when designing system timing. Verify that the 8-lead MSOP footprint aligns with the PCB layout constraints.

Memory IC Part Context

This device belongs to the 24XXX52 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA52 but offers higher clock frequency compatibility. The family provides flexible write protection options and utilizes standard I2C protocols for efficient communication in space-constrained electronic designs.

Memory IC Replacement Considerations

The 24LC52 series serves as a functional equivalent within the same product family. Substitution requires verifying that the alternative part supports the necessary 400 kHz clock frequency and matches the 8-lead MSOP physical dimensions.
