Overview

The AT24C02C is a 2Kbit (256-byte) non-volatile EEPROM memory IC utilizing an I2C-compatible serial interface. It operates across a wide voltage range of 1.7V to 5.5V and supports clock frequencies up to 1 MHz. This device is designed for general-purpose data storage in embedded systems.

Why Choose This Part

This EEPROM offers high reliability with 1,000,000 write cycles and 100 years of data retention, ensuring long-term data integrity. Its wide operating voltage range (1.7V to 5.5V) makes it suitable for various systems, including battery-powered devices. Features like Schmitt Triggers and filtered inputs provide robust operation in noisy environments, while the write-protect pin adds hardware data protection.

Applications

Configuration Storage
Storing system configuration parameters that need to persist across power cycles, such as user settings, calibration data, or device identifiers.
Data Logging
Recording small amounts of event data or operational statistics in applications where power outages are common or long-term storage is required without battery backup.
Peripheral Status Memory
Retaining the last known state of a peripheral or system component for faster startup or recovery after a reset.
Bootloader Parameters
Storing bootloader flags or firmware update status to manage system initialization and update processes reliably.

Getting Started

To get started with the AT24C02C, connect its SDA and SCL pins to an I2C master (e.g., a microcontroller). Most modern microcontrollers have built-in I2C peripherals and libraries, simplifying communication. Ensure appropriate pull-up resistors are used on the I2C lines. Refer to the device datasheet for I2C slave address and command protocols for read and write operations.
