24LC04B-E/P

Memory IC Overview

The Microchip Technology 24LC04B-E/P is a 4-Kbit (512 x 8) serial EEPROM featuring an I²C-compatible two-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead PDIP package and functions across an extended temperature range from -40°C to +125°C. Key electrical specifications include a maximum access time of 900 ns, standby current of 5 µA, and write cycle endurance exceeding one million cycles with data retention lasting over 200 years.

Memory IC Feature Summary

• Hardware write protection via the WP pin
• Schmitt trigger inputs for noise suppression
• Self-timed erase/write cycles with page write capability
• High ESD protection rating

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control units operating in high-temperature environments
• Consumer electronics utilizing low-power memory solutions
• Automotive applications meeting AEC-Q100 qualification standards

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended temperature grade (-40°C to +125°C) and 'P' indicates the PDIP package. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the source document explicitly lists this part number as available or discontinued before finalizing procurement plans.

Memory IC Selection Notes

Select this component when an industrial-grade I²C EEPROM is required for harsh thermal conditions. The 24LC04B variant specifically requires a minimum supply voltage of 2.5V, distinguishing it from lower-voltage counterparts. The PDIP package is suitable for through-hole mounting requirements where surface-mount options are not feasible.

Memory IC Part Context

This device belongs to the 24XX04 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA04 and 24FC04 models but differs in voltage thresholds and clock speed capabilities. The 24LC04B series provides a balance of performance and reliability for general-purpose memory storage tasks.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04B variants with different packages such as MSOP or SOIC. Cross-referencing with 24AA04 or 24FC04 models requires verifying voltage compatibility and clock frequency limits.
