Microchip 24LC64FT-I/OT: A Deep Dive into its Features, Diverse Applications, and Technical Specifications

The Microchip 24LC64FT-I/OT stands as a prominent solution in the realm of serial memory, offering designers a reliable and efficient method for non-volatile data storage. As a 64Kbit I2C Serial EEPROM, this device provides a robust combination of density, performance, and low-power operation, making it a versatile component across countless electronic applications.

Key Features and Technical Overview

This memory IC is organized as 8,192 words x 8 bits (8K x 8), providing ample space for storing configuration parameters, calibration data, and event logs. Its operation is centered on the ubiquitous I2C (Inter- Two-Wire) serial interface, which allows for communication with a microcontroller using only two bidirectional lines: Serial Clock (SCL) and Serial Data (SDA). This drastically reduces the required pin count and simplifies board layout.

A critical feature of the 24LC64FT is its 1.7V to 5.5V wide voltage range operation. This allows the device to function seamlessly in both modern low-voltage systems and legacy 5V designs, ensuring broad compatibility. Furthermore, it is characterized for operation across the expansive -40°C to +85°C industrial temperature range, guaranteeing reliability in harsh environmental conditions.

The device incorporates advanced write-protection mechanisms. A hardware Write-Protect (WP) pin allows the entire memory array to be locked against inadvertent write operations, safeguarding critical data. Internally, it features a page write buffer capable of up to 128 bytes, enabling faster data throughput by writing multiple bytes in a single operation instead of individual byte writes.

Its packaging, the SOT-23-5, is one of its most significant advantages. This ultra-small footprint is essential for space-constrained applications like wearable technology and compact sensor modules. The device also offers high endurance, supporting 1,000,000 erase/write cycles per byte and boasts 200-year data retention.

Diverse Application Spectrum

The combination of its small size, low power, and simple interface makes the 24LC64FT-I/OT incredibly versatile. Its primary applications include:

Consumer Electronics: Storing user settings and calibration data in smart home devices, televisions, and audio equipment.

Medical Devices: Safely retaining patient data and device configuration in portable monitors and diagnostic tools.

Industrial Systems: Used in PLCs, instrumentation, and control systems for logging operational data and parameters.

Automotive Electronics: Employed in modules requiring non-volatile memory outside of extreme under-hood environments.

IoT and Wearables: The tiny SOT-23 package and low power consumption make it ideal for sensor data logging and device profiling in compact, battery-powered applications.

ICGOODFIND: The Microchip 24LC64FT-I/OT is a highly integrated and robust 64Kbit serial EEPROM. Its industry-standard I2C interface, ultra-small SOT-23 packaging, wide voltage range, and exceptional reliability make it an outstanding choice for designers seeking a proven non-volatile memory solution for modern, space-sensitive electronic products.
