Overview

The 24LC64-I/MS is a 64Kbit (8K x 8) I2C serial EEPROM designed for low-power applications with a wide operating voltage range from 2.5V to 5.5V. This non-volatile memory supports a 400 kHz clock frequency and features hardware write protection to safeguard data from accidental modification. It is housed in a compact 8-lead MSOP package, making it suitable for space-constrained designs requiring persistent storage.

Why Choose This Part

This device features more than 1 million erase/write cycles and over 200 years of data retention for extreme reliability. The integration of Schmitt Trigger inputs and output slope control helps minimize noise and ground bounce in noisy environments. Its ultra-low power consumption, with a standby current of only 1 uA, is ideal for battery-operated devices.

Applications

Configuration Storage
Storing user preferences, calibration data, and system settings in industrial or consumer electronics.
Event Logging
Recording error codes or operational timestamps in embedded systems with low-frequency logging requirements.
Identification Data
Storing serial numbers, MAC addresses, and revision data for hardware identification and asset tracking.

Getting Started

To interface with the 24LC64-I/MS, connect the SDA and SCL lines to a microcontroller's I2C bus using 4.7k or 10k ohm pull-up resistors. Ensure the WP (Write Protect) pin is tied to GND for normal write operations or VCC to protect the memory array. Library support is widely available for platforms like PIC, AVR, and Arduino, requiring only the device address to be configured.
