24LC014HT-E/MS

Memory IC Overview

The Microchip Technology 24LC014HT-E/MS 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 page write buffer of 16 bytes, and low-power CMOS technology with maximum active current of 400 μA and standby current of 1 μA. It is housed in an 8-lead MSOP package and rated for extended temperature operation 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.
• Page write capability allows storage of up to 16 bytes in a single bus transaction using an internal buffer.
• Schmitt trigger inputs and output slope control provide noise suppression and eliminate ground bounce effects.

Memory IC Applications

• Data logging in industrial systems requiring non-volatile storage
• Configuration parameter storage in automotive electronics
• Calibration data retention in sensor modules

Memory IC Procurement Notes

Verify that the ordering suffix 'HT' corresponds to tape-and-reel packaging as specified by the manufacturer. Confirm the 'E' suffix indicates the extended temperature grade (-40°C to +125°C). Ensure the 'MS' suffix matches the required 8-lead MSOP package type. Cross-reference the full part number against the latest Microchip datasheet DS22077B to confirm functional compatibility and electrical specifications.

Memory IC Selection Notes

Select this component when high-speed 1 MHz I²C communication is required alongside extended temperature resilience. The 24LC014H series offers faster performance than standard 400 kHz variants. Consider the hardware write protection feature if security against accidental overwrites is critical. Verify that the 2.5V minimum supply voltage aligns with the system's power rails.

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 is distinguished by its 1 MHz clock speed capability and specific package designation. The 'LC' variant denotes the higher frequency operation compared to the 'AA' or standard 'LC' models limited to 400 kHz.

Memory IC Replacement Considerations

Direct substitutes include other 24LC014H variants with different packages, such as 24LC014H-I/MS or 24LC014H-E/SN, provided the temperature grade and interface timing requirements are met. Ensure any replacement maintains the 1 MHz clock specification and 8-lead MSOP form factor.
