(file size: 1102186, 32 pages, revision B, updated: 08/2007)
This application note is an aid for developers in the design of a system using the Two-wire Interface (TWI) of Atmel's AT91SAM family of microcontroller products with Atmel's Two-wire Interface slave devices and I2C-Bus compatible slave devices. It describes the connection with a digital temperature sensor (LM75), a Real Time Clock (DS1337), a Graphic LCD Module(PCF8558) and a 1Mbit Two-wire Serial EEPROM (AT24C1024).
