MCHP24LC02B-I/SN
Overview
The 24LC02B-I/SN is a 2-Kbit I2C serial EEPROM designed for non-volatile storage in space-constrained surface-mount applications. It operates over a wide voltage range of 2.5V to 5.5V and supports a 400 kHz clock frequency for reliable communication with microcontrollers. This SOIC-8 package variant is ideal for production environments requiring low-power, robust data retention.
Why Choose This Part
This EEPROM offers high endurance with over 1 million erase/write cycles and exceptional data retention exceeding 200 years. Its low-power CMOS technology consumes only 1mA during active read/write and 1 microamp in standby, making it suitable for energy-sensitive designs. Features like Schmitt trigger inputs and output slope control enhance noise immunity and signal integrity.
Applications
Key Specifications
Getting Started
To integrate this part, connect the SDA and SCL lines to your microcontroller I2C bus with external pull-up resistors, typically 4.7k ohms. Ensure the hardware write-protect (WP) pin is tied to ground for write operations or VCC to protect data. Standard I2C libraries like Wire for Arduino or Microchip MCC can be used to perform byte or page writes to the 256-byte memory space.
