18  R/F Converter (RFC)

18.1  Overview

The RFC is a CR oscillation type A/D converter (R/F converter).
The features of the RFC are listed below.
•  Converts the sensor resistance into a digital value by performing CR oscillation and counting the oscillation 

clock.

•  Achieves high-precision measurement system with low errors by oscillating the reference resistor and the sensor 

in the same conditions to obtain the difference between them.

•  Includes a 24-bit measurement counter to count the oscillation clocks.
•  Includes a 24-bit time base counter to count the internal clock for equalizing the measurement time between the 

reference resistor and the sensor.

•  Supports DC bias resistive sensors and AC bias resistive sensors. 

(Note: See the table below.)

  (A thermometer/hygrometer can be easily implemented by connecting a thermistor or a humidity sensor and a 

few passive elements (resistor and capacitor).)

•  Allows measurement (counting) by inputting external clocks.
•  Provides an output and continuous oscillation function for monitoring the oscillation frequency.
•  Can generate reference oscillation completion, sensor (A and B) oscillation completion, measurement counter 

overflow error, and time base counter overflow error interrupts.

Figure 18.1.1 shows the RFC configuration.
