Application Circuits
Notes: Substrate connect to VDD.
VEE, CAP and C512 are externally connected to capacitors for stabilizing VEE (=–1.5V).
BZ1 and BZ2 are connected to an external Buzzer for generating sounds.
LOWC is connected to an external resistor for adjusting the detector level of a low voltage
detector. 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.
RE F (reference resistor) is a resistor value equal to 503E T sensor in 37.00
°
C.
SE NSOR is a 503E T thermistor.
