Hi Nidhin,

I suggest you start by reading the section labeled "Serial Interface" in the datasheet. You can find the datasheet here: http://focus.ti.com/lit/ds/symlink/tmp112.pdf . Then, if you still have specific questions, you can post those here.

This device is a slave on a two-wire serial bus, also known as I2C or SMBus.

The easiest way to talk to it would be to find I2C or SMBus code examples packed in with your microcontroller. Start out just trying to do a read operation. It should respond with temperature.
