Overview

The 24FC512-I/P is a 512Kbit (64K x 8) serial EEPROM designed for high-speed non-volatile data storage. It operates across a wide voltage range of 1.7V to 5.5V and supports I2C clock frequencies up to 1 MHz. This specific variant comes in an 8-pin PDIP package, making it an ideal choice for prototyping and through-hole assembly.

Why Choose This Part

This component features an extremely low standby current of 1 microamp, making it suitable for battery-powered applications. Its support for 1 MHz I2C bus speeds allows for faster data throughput compared to standard 400 kHz EEPROMs, while the through-hole PDIP package simplifies breadboarding and manual soldering.

Applications

Configuration Storage
Storing calibration constants, user settings, and network configuration data that must persist through power cycles.
Data Logging
Capturing sensor readings or event logs in low-power remote monitoring systems.
Bootloader Storage
Holding firmware update images or secondary boot code for microcontrollers with limited internal flash.

Getting Started

To interface with this EEPROM, connect the SDA and SCL pins to your microcontroller's I2C bus with appropriate pull-up resistors. Address pins A0, A1, and A2 allow up to eight devices on the same bus. Most standard I2C libraries (such as Wire for Arduino) support this device using its 7-bit hardware address.
