Thermal Sensor with SPI Interface

Microchip Technology 

TC77

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.
