The Atmel Two-wire Interface Master (TWIM) interconnects components on a unique two-wire
bus, made up of one clock line and one data line with speeds of up to 400 kbit/s, based on a
byte-oriented transfer format. It can be used with any Atmel Two-wire Interface bus serial
EEPROM and I²C compatible device such as a real rime clock (RTC), dot matrix/graphic LCD
controller and temperature sensor, to name a few. TWIM is always a bus master and can trans-
fer sequential or single bytes. Multiple master capability is supported. Arbitration of the bus is
performed internally and relinquishes the bus automatically if the bus arbitration is lost.
A configurable baud rate generator permits the output data rate to be adapted to a wide range of
core clock frequencies.
Interface in Master Mode and a full I²C compatible device.
