24LC014-I/SN

Memory IC Overview

The Microchip Technology 24LC014-I/SN is a 1 Kbit (128 x 8) serial electrically erasable PROM featuring a 2-wire I²C compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device supports hardware write protection, page writes up to 16 bytes, and offers 1,000,000 erase/write cycles with data retention exceeding 200 years. It 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

• Supports bidirectional 2-wire serial communication via I²C bus protocol
• Includes hardware write protection pin for entire array security
• Features self-timed write cycle with internal auto-erase capability
• Provides address lines allowing connection of up to eight devices on the same bus

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control units needing parameter logging
• Consumer electronics utilizing low-power memory solutions
• Automotive modules operating within specified temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type, specifically SOIC for this model. Confirm the temperature grade corresponds to Industrial specifications (-40°C to +85°C). Ensure compatibility with the system's I²C bus voltage levels and pull-up resistor requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application needs. Choose the SOIC package for surface mount assembly constraints. Consider the 400 kHz clock speed for faster data transfer requirements compared to standard 100 kHz modes. Evaluate the hardware write protection feature if data integrity against accidental overwrites is critical for the design.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. The 'I' suffix denotes the Industrial temperature grade, while 'SN' specifies the 8-lead Small Outline Integrated Circuit package. It shares functional similarities with other members of the series but differs in voltage ranges and packaging options.
