Description
The TC77 is a serially accessible digital temperature
sensor particularly suited for low cost and small form-
factor applications. Temperature data is converted from
the internal thermal sensing element and made avail-
able at anytime as a 13-bit two’s compliment digital
word. Communication with the TC77 is accomplished
via a SPI and MICROWIRE compatible interface. It has
a 12-bit plus sign temperature resolution of 0.0625°C
per Least Significant Bit (LSb). The TC77 offers a tem-
perature accuracy of ±1.0°C (max.) over the tempera-
ture range of +25°C to +65°C. When operating, the
TC77 consumes only 250 µA (typ.). The TC77’s Con-
figuration register can be used to activate the low
power Shutdown mode, which has a current consump-
tion of only 0.1 µA (typ.). Small size, low cost and ease
of use make the TC77 an ideal choice for implementing
thermal management in a variety of systems.
