Application Circuits
Note: Substrate connect to VDD
VEE, CAP, and C512 are externally connected to capacitors for stabilizing V
EE
(= 1.5V).
BZ1 and BZ2 are connected to an external buzzer to generate sounds.
LOWC is connected to an external resistor for adjusting the detector level of a low voltage de-
tector. Open the pin when not in use.
OSCI, OSCO are connected to an external resistor, and form an RC oscillator with a built-in
capacitor for SYSTEM clock (=32kHz)
RS, RF, SC constitute an alternating RC oscillator, which allows one oscillator, namely RS or
RF, active at a time.
REF (reference resistor) is a resistor value equal to 503ET, sensor is value in 37.0 C or 98.6 F.
SENSOR is a 503ET thermistor.
