CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (A/D Converter)
Connect a reference resistance that only slightly changes
resistance values according to environmental conditions
between the oscillating I/O terminals RS and CS. Connect a
sensor that changes resistance values between the TH and
CS terminals. Furthermore, by connecting a condenser
between the CS and VSS, a CR oscillation circuit is com-
pleted.
This A/D converter performs CR oscillation using one of the
two resistances connected to external devices. Their oscilla-
tion frequency serves as a clock from which the oscillation
frequency is counted. Difference in counted oscillation
frequency can be evaluated in terms of the difference be-
tween the respective resistance values. Measurement results
can be obtained from the changes in resistance values after
correcting the difference according to the program.
(1) External resistances and condenser
Connect a sensor (a variable resistance element such as a
thermistor) between the TH and CS terminals.
Next, set the reference value of the item to be measured
(e.g. reference temperature in the case of temperature
measurement) and connect the reference resistance
equivalent to the sensor resistance value at the above
reference value between the RS and CS terminals. An
element that does not change due to temperature or other
environmental conditions must be used as the reference
resistance.
Connect an oscillating condenser that is used for CR
oscillation of both the reference resistance and the sensor
between the CS and VSS terminals.
