24LC014-E/SN

Memory IC Overview

The Microchip Technology 24LC014-E/SN is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a maximum clock frequency of 400 kHz. The device supports hardware write protection via the WP pin and includes a page write buffer for up to 16 bytes. It offers 1,000,000 erase/write cycles, data retention exceeding 200 years, and ESD protection greater than 4,000V. The component is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection for the entire memory array
• Page write capability supporting up to 16 bytes per cycle
• I²C compatible bidirectional serial bus interface
• High endurance with one million erase/write cycles

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Embedded devices needing configuration parameter retention
• Automotive electronics operating under extended temperature conditions
• Smart metering applications for secure data logging

Memory IC Procurement Notes

Verify that the ordering suffix 'E' corresponds to the automotive temperature grade (-40°C to +125°C) as specified in the datasheet selection table, while the 'SN' suffix confirms the 8-lead SOIC package. Confirm RoHS compliance status directly with the manufacturer documentation prior to procurement to ensure adherence to environmental regulations.

Memory IC Selection Notes

Select this component when an I²C interface is required for low-pin-count memory expansion. Ensure the system voltage remains within the 2.5 V to 5.5 V operational range. Consider the 400 kHz clock speed for bandwidth requirements and verify that the 8-lead SOIC package fits the available PCB footprint constraints.

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 voltage applications compared to the 24AA series which supports lower voltages down to 1.7V.

Memory IC Replacement Considerations

The 24LC014-I/SN serves as a direct substitute if the industrial temperature grade (-40°C to +85°C) suffices for the application. Other variants within the 24LC014H or 24LC014HT families offer higher clock speeds but require verification of electrical compatibility.
