Title:
Interfacing the TC77 Thermal Sensor to a PICmicro® Microcontroller

Description:

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.

Microchip has developed a hardware platform called the PICkit™ 1 FLASH Starter Kit, allowing the designer to quickly begin their system development. Additionally, Microchip has developed a TC77 PICtail™ Daughter Board that interfaces directly to the PICkit 1 FLASH Starter Kit. These two boards are used to demonstrate the techniques for integrating the TC77 into an embedded systems environment. Both of these development boards are available on the Microchip web site at www.microchip.com.
