Overview
20.1
TEM is a temperature detection circuit including a temperature sensor. The features of TEM are listed below.
• Temperature sensor detectable temperature range: -20 °C to 70 °C
• Sensor output voltage to digital value (8 bits) conversion circuit
• Conversion time (comparison time) adjustment function
*
TEM compares the sensor detection voltage with the reference voltage.
• Can generate conversion completion interrupts.
Figure 20.1.1 shows TEM configuration.
