Atmel AVR is using a RTC PCF8533. Use the I² C-Lib from Peter Fleury http://jump.to/fleury for the communication to the chip.

This program is designed to work with the Arduino, and is saved in a format recognized by Arduino1.0. This is a program that uses the MLX90614 Thermal sensor, and fleury s I2Clibrary.-This program is designed to work with the Arduino, and is saved in
