24LC04BHT-I/OT

Memory IC Overview

The Microchip Technology 24LC04BHT-I/OT is a 4-Kbit Electrically Erasable PROM (EEPROM) organized as two blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device operates on a single supply voltage ranging from 2.5V to 5.5V. Key electrical parameters include a maximum access time of 900 ns, a page write time of 5 ms maximum, and an active read current of up to 3 mA at 5.5V. Standby current is limited to 5 µA maximum in extended temperature conditions.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycles with acknowledge polling support
• High reliability specifications including over one million erase/write cycles and data retention exceeding 200 years

Memory IC Applications

• Industrial embedded systems requiring non-volatile data storage
• Automotive electronics applications meeting AEC-Q100 qualification standards
• Consumer devices needing low-power configuration memory
• IoT sensors utilizing half-array write protection for critical data segments

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the SOT-23-5 package type and Industrial temperature grade (-40°C to +85°C). Confirm that the Extended temperature variant (-40°C to +125°C) requires the 'E' suffix rather than 'I'. Ensure compatibility with the 2.5V minimum operating voltage requirement for this specific device family member before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact SOT-23-5 footprint is required alongside hardware write protection for half the memory space. It is suitable for designs operating strictly within the 2.5V to 5.5V range. Consider alternative packages like MSOP or SOIC if larger surface area is acceptable, or different series members if lower voltage operation below 2.5V is necessary.

Memory IC Part Context

This part belongs to the 24LC04BH series, which introduces half-array write protection compared to standard 24LC04B models. It shares the same 4Kbit capacity and I2C interface but adds the WP pin functionality. The 'T' indicates the SOT-23-5 package, while 'I' denotes the industrial temperature rating. It complements the 24AA04H and 24FC04H variants within the broader 24XX04H family.

Memory IC Replacement Considerations

Direct functional substitutes include other 24LC04BH variants in different packages such as 24LC04BHT-I/MS or 24LC04BHT-I/SN. For identical performance in the same package, verify availability of 24LC04BHT-I/OT from authorized distributors. Cross-reference with 24AA04H only if voltage requirements allow down to 1.7V.
