1 / 24 page  2002 Microchip Technology Inc. DS21743A-page 1 M TC72 Features • Temperature-to-Digital Converter • SPI™ Compatible Interface • 10-Bit Resolution (0.25°C/Bit) • ±2°C (max.) Accuracy from -40°C to +85°C • ±3°C (max.) Accuracy from -55°C to +125°C • 2.65V to 5.5V Operating Range • Low Power Consumption: - 250 µA (typ.) Continuous Temperature Conversion Mode - 1 µA (max.) Shutdown Mode • Power Saving One-Shot Temperature Measurement • Industry Standard 8-Pin MSOP Package • Space Saving 8-Pin DFN (3x3 mm) Package Typical Applications • Personal Computers and Servers • Hard Disk Drives and Other PC Peripherals • Entertainment Systems • Office Equipment • Datacom Equipment • Mobile Phones • General Purpose Temperature Monitoring Package Types General Description The TC72 is a digital temperature sensor capable of reading temperatures from -55°C to +125°C. This sen- sor features a serial interface that allows communica- tion with a host controller or other peripherals. The TC72 interface is compatible with the SPI protocol. The TC72 does not require any additional external compo- nents. However, it is recommended that a decoupling capacitor of 0.01 µF to 0.1 µF be provided between the VDD and GND pins. The TC72 can be used either in a Continuous Temper- ature Conversion mode or a One-Shot Conversion mode. The Continuous Conversion mode measures the temperature approximately every 150 ms and stores the data in the temperature registers. In con- trast, the One-Shot mode performs a single tempera- ture measurement and returns to the power saving shutdown mode. The TC72 features high temperature accuracy, ease- of-use and is the ideal solution for implementing ther- mal management in a variety of systems. The device is available in both 8-pin MSOP and 8-pin DFN space- saving packages. The TC72 also features a shutdown mode for low power operation.
