MCHPAT24C02D-MAHM-T
Overview
The AT24C02D-MAHM-T is a 2Kbit serial EEPROM organized as 256 bytes of 8 bits each, designed for low-power and low-voltage applications. It operates over a wide voltage range of 1.7V to 3.6V and utilizes a standard I2C (Two-Wire) serial interface capable of speeds up to 1 MHz. This component is housed in a space-saving 8-pad UDFN package, making it ideal for compact embedded systems requiring non-volatile parameter storage.
Why Choose This Part
The device features a high endurance rating of 1,000,000 write cycles and 100-year data retention for long-term reliability. It includes hardware write protection and Schmitt triggers on inputs for noise suppression, which is critical in industrial environments. The 5ms maximum self-timed write cycle and 8-byte page write mode allow for efficient data updates.
Applications
Key Specifications
Getting Started
Interface the AT24C02D to any MCU with an I2C peripheral by connecting the SDA and SCL lines with appropriate pull-up resistors. Ensure the WP (Write Protect) pin is tied to GND for normal write operations or VCC to protect the memory. For rapid prototyping, use a standard I2C library such as the Arduino Wire library or Microchip's MPLAB Code Configurator (MCC) to generate the driver code.
