24LC024H-I/MS

Memory IC Overview

The Microchip Technology 24LC024H-I/MS is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 1 MHz. The device features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It includes a hardware write-protect pin that secures the upper half of the array (addresses 80h-FFh). The component supports page writes of up to 16 bytes, offers 1 million erase/write cycles, and ensures data retention exceeding 200 years.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• I²C compatible 2-wire serial interface supporting up to 1 MHz clock frequency
• Schmitt trigger inputs and output slope control for enhanced noise immunity

Memory IC Applications

• Low-power sensor nodes requiring non-volatile data storage
• Industrial controllers needing reliable parameter retention
• Embedded systems utilizing multiple devices on a shared I²C bus

Memory IC Procurement Notes

Verify the specific suffix 'I/MS' confirms the Industrial temperature range (-40°C to +85°C) and MSOP package. Confirm RoHS compliance status as per the latest datasheet revision. Ensure the ordering code matches the exact capacity and interface requirements for the target application design.

Memory IC Selection Notes

Select this part when a 1 MHz I²C speed is required within the 2.5V to 5.5V voltage range. The 'H' variant provides wider voltage compatibility compared to standard versions. Consider the MSOP package dimensions for PCB layout constraints. Verify that the hardware write-protect feature aligns with the system's security requirements for the protected memory region.

Memory IC Part Context

This component belongs to the 24AA024H/24LC024H family of 2 Kbit Serial Electrically Erasable PROMs. The 'LC' designation indicates support for higher clock frequencies up to 1 MHz, distinguishing it from the 'AA' variant limited to 400 kHz. The 'I' suffix denotes the industrial temperature grade, while 'MSOP' specifies the 8-lead Mini Small Outline Package.

Memory IC Replacement Considerations

The 24LC024H-E/MS serves as a direct replacement for extended temperature applications (-40°C to +125°C). Other variants in the 24LC024 series may differ in package type or voltage specifications.
