24LC024H-E/SN16KVAO

Memory IC Overview

The Microchip 24LC024H-E/SN16KVAO 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 and supports clock frequencies up to 1 MHz. The device features hardware write protection for the upper half of the memory array, ensuring data integrity against accidental modification. It includes Schmitt trigger inputs for noise suppression and output slope control to minimize ground bounce.

Memory IC Feature Summary

• Hardware write protection locks the upper half of the memory array when the WP pin is tied high.
• Supports standard and fast-mode I²C communication with compatibility up to 1 MHz.
• Incorporates Schmitt trigger inputs and spike suppression filters for reliable operation in noisy environments.

Memory IC Applications

• Industrial controllers requiring non-volatile storage for configuration parameters
• Sensor nodes needing low-power data retention
• Embedded systems utilizing multiple devices on a shared I²C bus
• Automotive electronics operating within extended temperature ranges

Memory IC Procurement Notes

Verify that the specific suffix 'SN16KVAO' aligns with the manufacturer's current ordering nomenclature, as datasheets typically reference standard package codes like SN for SOIC. Confirm RoHS compliance status directly with the supplier or official documentation, as packaging variations may affect environmental certifications. Ensure the automotive grade designation matches project requirements.

Memory IC Selection Notes

Select this component when a 2 Kbit capacity is sufficient for application needs. The 24LC024H variant is appropriate for designs requiring operation down to 2.5V, distinguishing it from the wider voltage range 24AA024H. The industrial/automotive temperature rating (-40°C to +125°C) suits harsh environments. Verify that the 8-pin SOIC package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the 24AA024H/24LC024H family of 2 Kbit Serial Electrically Erasable PROMs. These devices are designed for applications requiring small, non-volatile memory blocks accessible via a two-wire serial bus. The family offers various package options including PDIP, SOIC, TSSOP, MSOP, and TDFN to accommodate different board space and mounting requirements.

Memory IC Replacement Considerations

The 24LC024H-E/SN is a direct functional equivalent within the same series. For broader voltage compatibility (1.7V-5.5V), consider the 24AA024H-E/SN. Other capacities in the 24-series, such as the 24LC025 or 24LC02B, offer similar interfaces but differ in memory size or speed specifications.
