Overview

The 24LC512-I/SN is a 512 Kbit (64K x 8) Serial EEPROM capable of operating across a wide voltage range of 2.5V to 5.5V. It utilizes a standard 2-wire I2C interface and is designed for high-endurance non-volatile storage in industrial and automotive environments.

Why Choose This Part

This device features a low standby current of only 1 uA and supports up to 1 million erase/write cycles. It includes Schmitt Trigger inputs for noise suppression and hardware write-protect for improved data security.

Applications

Calibration Data Storage
Storing sensor offset and gain coefficients that must persist through power cycles in industrial instrumentation.
User Preference Logging
Saving configuration settings and user-defined profiles in consumer electronics and smart home devices.
Event Logging
Recording system faults or operational timestamps in automotive modules using its 128-byte page write capability.
Firmware Rollback Images
Holding backup bootloader code or recovery parameters for small microcontrollers.

Getting Started

Connect the SDA and SCL pins to your microcontroller's I2C bus with 4.7k ohm pull-up resistors. Ensure the A0, A1, and A2 pins are tied to VSS or VCC to set the device address, and use the 128-byte page write buffer to optimize write cycle times.
