24LC014-I/MS

Memory IC Overview

The Microchip Technology 24LC014-I/MS is a 1 Kbit (128 x 8) serial Electrically Erasable PROM featuring an I²C-compatible 2-wire interface. It operates within a supply voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, drawing typical active current of 1 mA and standby current of 1 µA at 5.5V. It offers hardware write protection, page write buffers for up to 16 bytes, and endures 1,000,000 erase/write cycles with data retention exceeding 200 years. The component is housed in an 8-lead MSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication compatible with standard I²C protocols
• Includes hardware write protection via the WP pin to inhibit array writes when tied high
• Features a page write buffer allowing storage of up to 16 bytes before internal programming
• Provides self-timed write cycles with automatic erase-before-write functionality

Memory IC Applications

• Embedded systems requiring non-volatile data storage for configuration parameters
• Industrial control units needing reliable memory for sensor calibration values
• Consumer electronics utilizing low-power microcontrollers for persistent settings
• Automotive modules operating within extended temperature ranges

Memory IC Procurement Notes

Verify that the ordering suffix matches the specific package type and temperature grade required for your design. Confirm that the voltage supply aligns with the 2.5V minimum requirement, as lower voltages may restrict clock speed or functionality. Ensure compatibility with the I²C bus pull-up resistor values for the intended clock frequency. Check for any recent Product Change Notifications regarding packaging or material composition updates.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient and low power consumption is critical. The 24LC014-I/MS is suitable for designs requiring hardware write protection and high endurance. Consider the MSOP package dimensions if space constraints exist on the PCB. Ensure the system voltage remains above 2.5V to maintain full 400 kHz operation capabilities without degradation.

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 range (-40°C to +85°C), while 'E' indicates Automotive grade. The 'MSOP' suffix specifies the 8-lead Mini Small Outline Package. This family shares functional similarities with other 24-series devices but differs in capacity and voltage specifications.

Memory IC Replacement Considerations

Direct substitutes include the 24LC014H-I/MS and 24LC014T-I/SN. Verify voltage ranges and package dimensions before substitution. The 24AA014 series offers similar functionality but supports lower voltages down to 1.7V.
