24FC16HT-I/OT

Memory IC Overview

The Microchip Technology 24FC16HT-I/OT is a 16-Kbit Electrically Erasable PROM organized as eight blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 1 MHz across a supply voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology with maximum standby current of 1 μA and read current of 1 mA. It includes hardware write-protect functionality for half the array (addresses 400h-7FFh) via the WP pin, operates within an industrial temperature range of -40°C to +85°C, and is housed in a 5-lead SOT-23 package.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication at full voltage range
• Provides hardware write protection for the upper half of the memory array
• Features Schmitt trigger inputs and output slope control for noise suppression
• Includes a 16-byte page write buffer for efficient data programming

Memory IC Applications

• Industrial systems requiring non-volatile data storage with write protection
• Embedded controllers needing low-power EEPROM with fast access
• Consumer electronics operating on single-supply voltages down to 1.7V

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'OT' indicates the 5-lead SOT-23 package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the specific revision of the datasheet matches the production lot requirements for electrical characteristics.

Memory IC Selection Notes

Select this component when a 16-Kbit capacity with 1 MHz bus speed is required under low-voltage conditions. The hardware write-protect feature distinguishes it from variants lacking the WP pin function. Verify that the system design accommodates the 5-lead SOT-23 footprint and that the master controller supports the necessary I2C start/stop conditions for reliable operation.

Memory IC Part Context

This part belongs to the 24XX16H family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA16H and 24LC16BH but offers superior clock frequency performance compared to the 400 kHz limited counterparts. The device is designed for applications demanding robust data retention and endurance in compact surface-mount environments.

Memory IC Replacement Considerations

Direct substitutes include other 16-Kbit I2C EEPROMs with identical pinouts and voltage ranges. Verify compatibility regarding page size, write cycle times, and I2C address codes before swapping. Ensure replacement parts support the same industrial temperature rating and package dimensions.
