24LC014T-I/OT

Memory IC Overview

The Microchip Technology 24LC014T-I/OT 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, 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 a 6-lead SOT-23 package and is rated for an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial data transmission via I2C compatible interface
• Includes hardware write protection circuitry for the entire memory array
• Features self-timed write cycles with automatic erase and page write buffer capability
• Provides high reliability with over 4,000V ESD protection and extended data retention

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration parameter storage in embedded controllers
• Calibration data retention for sensor modules
• Small-scale memory expansion for microcontroller-based designs

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'OT' denotes the 6-lead SOT-23 surface-mount package. Confirm that the specific revision matches the DS21809G datasheet requirements. Ensure compatibility with the system's I2C bus voltage levels and pull-up resistor configurations before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact 1 Kbit EEPROM solution is required for space-constrained applications. The SOT-23 package offers a small footprint suitable for dense PCB layouts. Choose this part over the 24AA014 variant if the application operates strictly within the 2.5V to 5.5V voltage range, as the AA series supports lower voltages down to 1.7V. Ensure the design accommodates the 400 kHz clock speed limitations.

Memory IC Part Context

This device belongs to the 24AA014/24LC014 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family shares identical functional architectures but differs in operating voltage ranges and temperature grades. The 24LC014 specifically targets standard 2.5V to 5.5V logic systems, distinguishing it from the broader voltage range capabilities of the 24AA014 counterpart within the same product line.
