24LC014T-E/OT

Memory IC Overview

The Microchip Technology 24LC014T-E/OT 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 utilizes low-power CMOS technology, offering typical active current of 1 mA and standby current of 1 µA at 5.5V. It supports page write buffers for up to 16 bytes and includes hardware write protection. The component is housed in an 8-lead TDFN package and is rated for an extended industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial bus with compatibility for both 100 kHz and 400 kHz clock frequencies.
• Features hardware write protection controlled by the WP pin to inhibit write operations while maintaining read access.
• Includes a page write buffer allowing storage of up to 16 bytes before initiating an internal self-timed write cycle.

Memory IC Applications

• Data logging systems requiring non-volatile memory retention
• Configuration storage for microcontroller-based embedded devices
• Parameter storage in industrial control equipment

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the voltage range aligns with the system power supply, as the 'E' variant specifies a minimum operating voltage of 2.5V. Ensure the design accounts for the TDFN package thermal characteristics and mounting requirements specified in the datasheet.

Memory IC Selection Notes

Select this component when an I²C interface is required for small capacity non-volatile storage in automotive or industrial environments. The extended temperature rating makes it suitable for applications exceeding standard commercial limits. Consider the page write capability for efficient data block transfers and the hardware write protection for critical data integrity.

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 specifications but differs in voltage ranges and temperature grades. The 24LC series is optimized for lower voltage operation compared to the 24AA series, though this specific automotive-grade variant starts at 2.5V.

Memory IC Replacement Considerations

Direct substitutes within the same family include other 24LC014 variants with different packages such as SOIC or TSSOP. Cross-family replacements like the 24LC01B offer similar functionality but may have different electrical characteristics or pinouts. Verify compatibility with existing board layouts and software drivers when substituting.
