24LC024H-E/MS

Memory IC Overview

The Microchip Technology 24LC024H-E/MS is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 1 MHz. The device includes hardware write protection for the upper half of the memory array, ensuring data integrity against accidental writes. It offers high endurance with one million erase/write cycles and retains data for over 200 years.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Page write buffer supporting up to 16 bytes per transaction
• Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Embedded systems requiring non-volatile configuration storage
• Industrial controllers needing reliable parameter retention
• Low-power sensor nodes utilizing I²C bus connectivity

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP-8 package type and the Automotive temperature grade (-40°C to +125°C). Confirm the voltage range specification matches the LC variant requirements (2.5V to 5.5V) rather than the AA variant. Ensure compatibility with the intended I²C bus speed and check for RoHS compliance documentation.

Memory IC Selection Notes

Select this component when automotive-grade reliability is required alongside high-speed I²C communication. The 24LC024H series provides faster operation compared to standard 400 kHz variants. Consider the MSOP package for space-constrained designs. Verify that the system voltage remains above 2.5V to ensure proper functionality across the full operating temperature range.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit serial EEPROMs. The 'H' designation indicates support for higher clock speeds up to 1 MHz. The 'E' suffix denotes the extended industrial temperature range suitable for automotive applications. The 'MS' suffix identifies the 8-lead MSOP surface-mount package.

Memory IC Replacement Considerations

The 24LC024HT-I/MS is a compatible alternative within the same package but operates in the Industrial temperature range (-40°C to +85°C) instead of the Automotive range.
