RX23W Group 46. Temperature Sensor (TEMPSA)
46. Temperature Sensor (TEMPSA)
46.1 Overview
This MCU includes a temperature sensor. The temperature sensor outputs a voltage which varies with the temperature.
The user can obtain the temperature surrounding the MCU using the 12-bit A/D converter to convert the voltage output
from the temperature sensor into a digital value.
Table 46.1 lists the specifications of the temperature sensor. Figure 46.1 shows a overall block diagram of the
temperature sensor system.
