Silicon temperature sensors offer an easy-to-use alternativeto traditional temperature sensors, such as thermocouple,thermistors and RTDs. The TC77 SPI™Thermal Silicon Sensor is especially suited for embeddedsystems, due to its SPI interface. This serves toprovide a straight-forward and easy way to interface toa microcontroller. This application note will discusssystem integration, firmware implementation and PCBlayout techniques for the TC77 in an embeddedsystem.
