Silicon temperature sensors offer an easy-to-use alternative to traditional temperature sensors, such as thermocouple, thermistors and RTDs. The TC77 SPI™ Thermal Silicon Sensor is especially suited for embedded systems, due to its SPI interface. This serves to provide a straight-forward and easy way to interface to a microcontroller. This application note will discuss system integration, firmware implementation and PCB layout techniques for the TC77 in an embedded system.
