S1C60N02 TECHNICAL MANUAL
APPENDIX: TECHNICAL INFORMATION
The effect of the maximum 2 count error is given below.
1MAX (%) =
2
× 100 --- (1)
(fCLK/fCR1)
× CUPI1
2MAX (%) =
2
× 100 --- (2)
(fCLK/fCR2)
× CUPS
fCLK:
Clock frequency (32 kHz/64 kHz)
fCR1:
CR oscillation frequency by standard resistor
CUPI1: Up counter initial value (times)
1MAX:Maximum error (%) at CR oscillation by standard resistor
fCR2:
CR oscillation frequency by Thermistor
CUPS:
Thermistor count (times)
2MAX:Maximum error (%) at CR oscillation by Thermistor
In addition, the number of counts of the up-down counter should
be the same. Then the following equation is true:
fCLK × C
UPI1
=
fCLK × C
UPS
--- (3)
fCR1
fCR2
Then, from (3), assume the up-down counter counts shifted 2
counts, the following equations are true:
fCLK × C
UPI1
=
fCLK × C
UPS
±2
fCR1
fCR2
=
CUPS
± 2 × (fCR2/fCLK)
--- (3)'
fCR1
CUPI1
(1) is the count error at the CR oscillation by the standard resistor.
(2) is the count error at the CR oscillation by Thermistor.
The total error is expressed by the equation (3)' with the ratio of
fCR1 and fCR2.
The segment that represents the error in the equation (3)' is
±2 ×
(fCR2/fCLK). If the values CUPI1 and CUPS are large, this error factor
may be ignored.
For how to determine the initial value (CUPI1) of the up counter, see
the section describing thermometer design steps.
CR oscillation constant (K) error
The constant, K, is determined by the logic level of the internal
Schmidt trigger of the IC. However, in S1C60N02, the Schmidt
trigger shares the circuit with the standard resistor and Thermis-
tor. As a result, oscillation is canceled and no error occurs.
Error by transistor ON resistance
The transistor ON resistance is directly connected to the standard
resistor and Thermistor; this may cause an error.
See the circuit shown next to Figure B.2 below. In this circuit, the
capacitor is charged by Tr1, T2 ON and Tr3 OFF. If the voltage at
the CS pin changes to a certain level, the capacitor charge is
drained by Tr1, Tr2 OFF and Tr3 ON. As a result, the CR oscilla-
tion is generated as in Figure B.3.
