Product Features

1.1. Special Features

 General purpose series

 Not supposed to use in AC RC step-down powered or high EFT requirement applications.

PADAUK assumes no liability if such kind of applications can not pass the safety regulation tests.

 Operating temperature range: -40°C ~ 85°C

1.2. System Features

 2KW MTP program memory

 128 Bytes data RAM

 One hardware 16-bit timer

 Two hardware 8-bit timers with PWM generation

 Three hardware 11-bit PWM generators (PWMG0, PWMG1 & PWMG2)

 Provide one hardware comparator

 Provide 1T 8x8 hardware multiplier

 14 IO pins with optional pull-high resistor

 Every IO pin can be configured to enable wake-up function

 Bandgap circuit to provide 1.20V reference voltage

 Up to 12-channel 12-bit resolution ADC with one channel comes from internal Bandgap reference voltage or 0.25*VDD

 Provide ADC reference high voltage: external input, internal VDD, Bandgap(1.20V), 4V, 3V, 2.4V, 2V, 1.6V

 Clock sources: internal high RC oscillator(IHRC), internal low RC oscillator(ILRC) and external crystal oscillator(EOSC)

 For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast

 Built-in half VDD bias voltage generator to provide maximum 5x9 dots LCD display

 Eight levels of LVR reset: 4.0V, 3.5V, 3.0V, 2.75V, 2.5V, 2.2V, 2.0V, 1.8V

 Four selectable external interrupt pins

1.3. CPU Features
