24LC014T-E/MS

Memory IC Overview

The Microchip Technology 24LC014T-E/MS is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and features a 2-wire I²C compatible serial interface with a maximum clock frequency of 400 kHz. The device supports hardware write protection via the WP pin, page write buffers for up to 16 bytes, and acknowledge polling. It is housed in an 8-lead MSOP package and is rated for an extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission protocol compatible with standard I²C bus specifications.
• Includes hardware write protection circuitry that inhibits write operations when the WP pin is tied to VCC.
• Features a self-timed write cycle with internal erase/write timing, eliminating the need for external programming pulses.

Memory IC Applications

• Data storage in embedded systems requiring non-volatile memory retention
• Configuration parameter storage in industrial control devices
• Calibration data logging in automotive electronic modules

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging configuration. Confirm the 'E' suffix corresponds to the extended temperature grade (-40°C to +125°C) and the 'MS' suffix denotes the 8-lead MSOP package. Ensure compatibility with system voltage levels within the 2.5V to 5.5V operating range before integration.

Memory IC Selection Notes

Select this component for applications requiring robust data retention over extended temperature ranges. The MSOP package offers a compact surface-mount footprint suitable for space-constrained designs. The 400 kHz clock speed provides efficient data throughput for moderate-speed serial communication requirements.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but differs in voltage ranges and temperature grades. The 24LC series specifically targets standard 2.5V to 5.5V supply applications compared to the 1.7V capable 24AA series.

Memory IC Replacement Considerations

Direct substitutes include other 24LC014 variants with different packages or temperature grades, such as 24LC014-I/MS for industrial temperature or 24LC014-E/P for PDIP packaging. Cross-family replacements like 24AA014 require verification of minimum voltage compatibility.
