24VL024HT/ST

Memory IC Overview

The Microchip Technology 24VL024HT/ST is a 2 Kbit (256 x 8) serial EEPROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.5V to 3.6V and supports clock frequencies up to 400 kHz, with 100 kHz compatibility below 1.8V. The device includes hardware write protection for the upper half of the memory array via the WP pin and utilizes low-power CMOS technology.

Memory IC Feature Summary

• Low-voltage operation down to 1.5V with minimal active and standby current consumption
• Hardware write protection capability that secures the upper half of the memory array against unintended writes
• Integrated page write buffer allowing sequential storage of up to 16 bytes in a single bus transaction

Memory IC Applications

• Battery-powered embedded systems requiring extended data retention
• Industrial control units utilizing I²C communication buses
• Consumer electronics needing non-volatile configuration storage

Memory IC Procurement Notes

Verify the specific package suffix matches the required form factor, as the ST designation indicates TSSOP packaging. Confirm the temperature grade aligns with operational requirements, noting the standard industrial range extends to +85°C. Ensure the ordering code corresponds to the correct lead time and manufacturing lot specifications provided by authorized distributors.

Memory IC Selection Notes

Select this component when system power rails drop below 2.0V, as standard 2.5V EEPROMs may fail to operate. The 400 kHz speed rating suits high-throughput applications, while the 1.5V minimum enables deep sleep modes. Verify that the available physical space accommodates the TSSOP footprint and that the design accounts for the specific electrical characteristics of the lower voltage range.

Memory IC Part Context

This part belongs to the 24VL024H family, distinguished by its ultra-low voltage capability compared to the 2.5V-operating 24LC024H series. While functionally similar regarding memory organization and interface protocols, the VL variant specifically targets applications where power efficiency at reduced voltages is critical. It shares the same 2Kbit capacity and I²C protocol structure within the broader Microchip EEPROM portfolio.

Memory IC Replacement Considerations

The 24LC024HT/ST serves as a functional substitute if the application voltage remains above 2.5V. Other compatible replacements include the 24AA024HT/ST, which offers identical specifications but lacks the hardware write-protect pin.
