23.1 Overview
23.1.1
• 2-channel system by time division
23.1.2
This LSI has a built-in 2-channel RC oscillation type A/D converter (RC-ADC).
The RC-ADC converts resistance values or capacitance values to digital values by counting the oscillator clock whose
frequency changes according to the resistor or capacitor connected to the RC oscillator circuits. By using a thermistor
or humidity sensor as a resistor, a thermometer or hygrometer can be formed.
In addition, a different sensor for each of the two channels of RC-ADC’s RC oscillator circuit can be used to broaden
RC-ADC applications; for example, the conveter can be used for expansion of measurement range or measurement at
two points.
For input clock, see Chapter 6, “Clock Generation Circuit.”
The RC-ADC consists of two RC oscillator circuits to form two channels, Counter A (RADCA0–2) and Counter B
(RADCB0–2) as 24-bit binary counters, and an RC-ADC control circuit (RADCON, RADMOD). Figure 23-1 shows
the configuration of the RC-ADC.
