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.

• REF (reference resistor) is a resistor value equal to 503ET sensor in 37.00°C.

• SENSOR is a 503ET thermistor.
