24LC014H-E/P

Memory IC Overview

The Microchip Technology 24LC014H-E/P is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring a 2-wire I²C compatible interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 1 MHz. The device utilizes low-power CMOS technology, offering maximum active current of 400 μA and standby current of 1 μA. It includes hardware write protection for half the array, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper half of the memory array via the WP pin.
• Integrated Schmitt trigger inputs provide enhanced noise spike suppression on SDA and SCL lines.
• Output slope control circuitry minimizes ground bounce effects during high-speed switching operations.
• Supports acknowledge polling to maximize bus throughput by detecting internal write cycle completion.

Memory IC Applications

• Industrial systems requiring robust data retention in noisy environments
• Automotive electronics operating across extended temperature ranges
• Embedded controllers needing multiple devices on a single I²C bus

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the device meets RoHS compliance standards for your region. Ensure the supply voltage aligns with the 2.5V minimum requirement for the LC variant. Check datasheet revisions for any updates to electrical characteristics or pin configurations before finalizing procurement.

Memory IC Selection Notes

Select this component when an I²C EEPROM with hardware write protection is required. The E-temperature grade ensures operation from -40°C to +125°C, suitable for automotive applications. Choose this part over standard industrial grades if higher thermal stability is needed. Verify that the 1 MHz clock speed meets system timing requirements compared to slower 400 kHz alternatives.

Memory IC Part Context

This device belongs to the 24AA014H/24LC014H family of 1 Kbit serial EEPROMs. It shares architectural similarities with other members but differs in voltage range and speed capabilities. The 'E' suffix denotes an extended temperature grade, while 'P' indicates an 8-pin PDIP package. It complements lower-density and higher-density variants within the same product line.

Memory IC Replacement Considerations

Direct substitutes include the 24LC014H-I/P for industrial temperature ranges or the 24AA014H-E/P for wider voltage support down to 1.7V. Ensure compatibility with existing PCB footprints and software drivers when swapping between these variants.
