24LC014T-E/SN

Memory IC Overview

The Microchip Technology 24LC014T-E/SN is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports I²C™ compatible 2-wire serial interfaces with clock frequencies up to 400 kHz. The device features hardware write protection, self-timed write cycles of 5 ms maximum, and an endurance rating of 1,000,000 erase/write cycles. It is housed in an 8-lead SOIC package and is rated for industrial temperature ranges.

Memory IC Feature Summary

• Supports bidirectional data transfer via a 2-wire serial interface compatible with standard I²C protocols.
• Includes hardware write protection functionality controlled by the WP pin to inhibit array writes when enabled.
• Features a page write buffer allowing sequential storage of up to 16 bytes before initiating an internal write cycle.

Memory IC Applications

• Data logging applications requiring non-volatile storage of sensor readings or system parameters.
• Configuration storage for microcontroller-based systems needing persistent setting retention.
• Identification and calibration data storage in consumer electronics and industrial instrumentation.

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 'E' suffix indicates the extended temperature grade suitable for automotive or harsh industrial environments. Ensure compatibility with the target board's voltage levels and I²C bus pull-up requirements before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application needs and low power consumption is critical. The 400 kHz clock speed offers faster data throughput compared to 100 kHz variants. Consider the SOIC package dimensions for PCB layout constraints and verify that the 2.5 V minimum operating voltage aligns with the system's power supply rails.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 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 applications requiring operation down to 2.5 V, distinguishing it from the 24AA series which supports lower voltages starting at 1.7 V.

Memory IC Replacement Considerations

Direct replacements include other 24LC014 variants with different packaging or temperature ratings, such as 24LC014-I/SN for industrial temperatures or 24LC014-P for PDIP packages. Cross-family substitutes like the 24LC01B offer similar capacities but may differ in access times and buffer sizes.
