24LC024H-I/SN

Memory IC Overview

The Microchip Technology 24LC024H-I/SN is a 2 Kbit (256 x 8) serial electrically erasable PROM featuring an I²C-compatible 2-wire interface. It operates within a supply voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 1 MHz. The device utilizes low-power CMOS technology, with maximum active current of 400 μA and standby current of 1 μA. It includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.

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 cycle
• Schmitt trigger inputs and filter circuits for enhanced noise spike suppression
• Self-timed write cycles with automatic erase capabilities

Memory IC Applications

• Low-power sensor nodes requiring non-volatile data storage
• Industrial controllers needing hardware-level data protection
• Systems utilizing multiple devices on a single I²C bus
• Applications requiring high endurance and long-term data retention

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple physical formats. Confirm the temperature grade corresponds to the specific application environment requirements. Ensure the voltage specifications align with the system's power supply rails before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for the application. The 'I' suffix indicates an industrial temperature range suitable for standard commercial environments. The 'SN' suffix specifies the SOIC-8 package. Consider the 1 MHz clock speed if higher bus throughput is necessary compared to standard 400 kHz devices.

Memory IC Part Context

This device belongs to the 24AA024H/24LC024H family of serial EEPROMs. The 'LC' designation specifically denotes support for 1 MHz operation and a 2.5 V minimum supply voltage, distinguishing it from the 'AA' variant which supports lower voltages but limited to 400 kHz. The family shares identical pinouts and functional protocols across different capacities and packages.

Memory IC Replacement Considerations

Direct replacements include other 24LC024H variants with different package suffixes such as 24LC024H-I/MS or 24LC024H-I/SN. Cross-referencing with the 24AA024H series requires verifying voltage compatibility, as the AA series supports lower voltages.
