8 / 22 page TC77 DS20092A-page 8 2002 Microchip Technology Inc. 3.0 FUNCTIONAL DESCRIPTION The TC77 consists of a band-gap type temperature sensor, a 12-bit plus sign (13-bit) Sigma-Delta Analog- to-Digital Converter (ADC), an internal conversion oscillator (~30 kHz) and a serial input/output port. These devices feature a three-wire serial interface that is fully compatible with SPI and MICROWIRE specifica- tions and, therefore, allows simple communications with common microcontrollers and processors. The Shutdown mode can be used to reduce supply current for power sensitive applications. A Manufacturer’s ID register identifies the TC77 as a Microchip Technology product.
