the DS1620 is a great temperature sensor from dallas semi. it sends its data in parallel, leaving the serial port of the micro free for other stuff.

This is a two wire serial interface chip. It does not require a UART, so the UART port of the micro is available. However, its temperature data is presented one bit at a time for each clock pulse. Perhaps you were thinking of another part number?
