24LC04BH-E/P

Memory IC Overview

The Microchip Technology 24LC04BH-E/P is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write protection for the upper half of the memory array, low-power CMOS technology with standby current as low as 5 µA in extended temperature ranges, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead PDIP package and rated for operation between -40°C and +125°C.

Memory IC Feature Summary

• Hardware write protection for the upper half of the memory array via the WP pin
• Low-power CMOS technology with minimal active and standby current consumption
• I2C compatible two-wire serial interface with Schmitt trigger inputs for noise suppression
• Self-timed erase/write cycles with page write capability

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating in extended temperature environments
• Consumer electronics utilizing I2C bus communication
• Automotive electronic modules requiring AEC-Q100 qualified components

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Extended temperature range (-40°C to +125°C) and 'P' indicates the 8-lead PDIP package. Confirm the 'BH' designation ensures the inclusion of the half-array hardware write protection feature. Ensure compatibility with the required 2.5V minimum supply voltage before procurement.

Memory IC Selection Notes

Select this component when a 4-Kbit EEPROM with hardware write protection is required for high-temperature industrial or automotive environments. It is suitable for designs needing I2C connectivity with a 400 kHz maximum clock rate and operation down to 2.5V. Consider alternative packages like MSOP or SOIC if surface mount technology is preferred over through-hole mounting.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA04H and 24FC04H but differs in supply voltage requirements and maximum clock frequency specifications. The 24LC04BH specifically targets applications requiring robust performance in extended temperature conditions with hardware-level write protection capabilities.

Memory IC Replacement Considerations

Direct substitutes within the same family include the 24LC04B series, though it lacks the specific half-array write protection feature found in the BH variant. Other compatible options may include the 24AA04H or 24FC04H, provided their respective voltage and speed requirements align with the system design constraints.
