Overview
The Digilent PmodTMP3 is a temperature sensor built around the Microchip TCN75AVUA.
1 Functional Description
The PmodTMP3 uses an 8-pin connector that allows for communication via I 2 C and provides pins to daisy-chain the
PmodTMP3 to other I 2 C devices. The PmodTMP3 also provides three 3-pin headers for selecting the I 2 C address of
the chip, and one 2-pin header for controlling external devices based upon temperature thresholds defined by the
user in software. Temperature data measured by the device is formatted in two’s compliment and may be
programmed for a resolution of 9-bits to 12-bits through the configuration register on the TCN75AVUA.
