24LC014T-E/MNY

Memory IC Overview

The Microchip Technology 24LC014T-E/MNY is a 1 Kbit (128 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 2.5V to 5.5V and features a 2-wire I²C compatible serial interface with a maximum clock frequency of 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 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 protocol compatible with standard I²C interfaces.
• Includes hardware write protection functionality controlled by the WP pin to inhibit write operations when tied high.
• Features self-timed write cycles with automatic erase-write sequences, eliminating the need for external programming pulses.

Memory IC Applications

• Data storage for configuration parameters in embedded systems
• Logging operational data in industrial monitoring equipment
• Storing calibration constants in automotive electronic control units

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and temperature grade. Confirm RoHS compliance status and lead-free material declarations against the latest manufacturer documentation. Ensure the supply voltage requirements align with the target system's power rails before integration.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with low power consumption and standard serial connectivity. Consider the 400 kHz clock speed for moderate data throughput needs. Evaluate the physical dimensions of the TDFN package against available PCB real estate constraints.

Memory IC Part Context

This part belongs to the 24AA014/24LC014 family of 1 Kbit EEPROMs manufactured by Microchip Technology. The 'LC' designation indicates operation down to 2.5V, distinguishing it from the 'AA' variant which supports lower voltages. The 'E' suffix denotes the extended temperature grade suitable for harsh environments.

Memory IC Replacement Considerations

The 24LC014HT-E/MNY serves as a direct functional substitute within the same package and electrical specification profile. Verify compatibility regarding the specific tape and reel packaging format if automated assembly is utilized.
