• Manufacturer Part Number: TC773.3MCTTR
• Description: Thermal Sensor with SPI Interface
• Manufacturer: MICROCHIP [Microchip Technology]

TC77
3.0
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.
