24LC04BH-E/MS

Memory IC Overview

The Microchip Technology 24LC04BH-E/MS is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a two-wire I2C compatible serial interface. The device features a 900 ns access time, a 5 ms maximum page write cycle, and a 16-byte page write buffer. Designed for extended industrial environments, it functions within a temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Hardware write protection capability for the upper half of the memory array when the WP pin is tied to VCC
• Integrated Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce
• Self-timed erase/write cycles with automatic acknowledgment polling support to maximize bus throughput

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control devices needing data retention under high ambient temperatures
• Consumer electronics utilizing low-power I2C communication protocols

Memory IC Procurement Notes

Verify that the ordering suffix 'E' confirms the Extended temperature grade (-40°C to +125°C) and 'MS' specifies the 8-lead MSOP package. Confirm the 'BH' designation indicates the Half-Array Write-Protect variant. Ensure the component meets RoHS compliance requirements for your specific manufacturing process.

Memory IC Selection Notes

Select this part when a 4-Kbit capacity is required with hardware-level write protection for critical data segments. The 2.5V minimum operating voltage makes it suitable for standard logic levels, while the 400 kHz speed supports moderate data transfer rates. Consider alternative packages like PDIP or SOIC if surface mount constraints are not applicable.

Memory IC Part Context

This component belongs to the 24XX04H family of 4-Kbit I2C Serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA04H and 24FC04H but is distinguished by its 2.5V minimum operating voltage requirement and 400 kHz maximum clock frequency specification.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24LC04BH series such as 24LC04BH-I/MS for Industrial temperature grades, or different package options like 24LC04BH-E/SN (SOIC). Cross-brand replacements require verification of I2C compatibility and voltage thresholds.
