3.12 Temperature Sensor
For temperature measurement and primarily as an application example, a silicon temperature sensor
KTY13-5 is connected to the input port of the 16-bit timer/event counter 00, equal to port P00 of the
MCU. The temperature sensor has a resistor range of R
25 min
= 1950 Ω and R
25 max
= 1990 Ω at 25°
centigrade, with I

= 1 mA. The distribution of the temperature factor k
T
is shown in Table 7:
