24LC014H-E/ST

Memory IC Overview

The Microchip Technology 24LC014H-E/ST is a 1 Kbit (128 x 8) serial EEPROM utilizing an I2C-compatible 2-wire interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 1 MHz. The device features hardware write protection for half the array, a 16-byte page write buffer, and access times as fast as 400 ns. It is housed in an 8-pin TSSOP package and rated for extended industrial temperatures from -40°C to +125°C.

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 and output slope control provide noise suppression and eliminate ground bounce.
• Supports acknowledge polling to maximize bus throughput during internal self-timed write cycles.

Memory IC Applications

• Industrial systems requiring non-volatile data storage with high noise immunity
• Automotive electronics operating under extended temperature conditions
• Embedded controllers needing multiple devices on a single I2C bus

Memory IC Procurement Notes

Verify that the ordering suffix 'ST' corresponds to the 8-lead Thin Shrink Small Outline Package (TSSOP). Confirm the 'E' suffix indicates the Extended Temperature grade (-40°C to +125°C), distinct from the Industrial grade. Ensure the specific datasheet revision matches the required electrical characteristics for your design.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient and operation above 2.5V is guaranteed. The 'LC' variant designation allows for 1 MHz clock speeds, unlike the 400 kHz limit of standard versions at lower voltages. Consider the TSSOP package dimensions against available PCB real estate compared to SOIC or MSOP alternatives.

Memory IC Part Context

This part belongs to the 24AA014H/24LC014H family of 1 Kbit Serial Electrically Erasable PROMs. The 'LC' series specifically denotes compatibility with 1 MHz clock rates at supply voltages between 2.5V and 5.5V. The 'E' temperature grade extends operational reliability beyond standard industrial limits, targeting automotive and harsh environment applications.

Memory IC Replacement Considerations

The 24LC014H-I/ST serves as a functional substitute if the application does not require the extended temperature rating. Verify that the replacement maintains the same TSSOP footprint and I2C protocol compatibility.
