General Description and Block Diagram
The PMS133/PMS134 family is an OTP-based CMOS 8-bit microcontroller with 12bit ADC. It employs RISC architecture and all the instructions are executed in one cycle except that some instructions are two cycles that handle indirect memory access.

FEATUREs
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: -20°C ~ 70°C

System Features
◆ One hardware 16-bit timer
◆ Two hardware 8-bit timers with PWM generation
◆ Three hardware 11-bit PWM generators (PWMG0, PWMG1 & PWMG2)
◆ One hardware comparator
◆ Band-gap circuit to provide 1.20V reference voltage
◆ Up to 14-channel 12-bit resolution ADC with one channel comes from internal band-gap reference voltage or 0.25*VDD
◆ ADC reference high voltage: external input, internal VDD, Band-gap 1.20V, 4V, 3V, 2V
◆ One 1T 8x8 hardware multiplier
◆ Max. 22 IO pins with optional pull-high resistor
◆ Three different IO Driving capability group to meet different application requirements
   (1) PB4, PB7 Drive/ Sink Current= 30mA/35mA (Strong) and 13mA/17mA (Normal)
   (2) Other IOs (except PA5) Drive/ Sink Current = 10mA/(13 or 20) mA
   (3) PA5 Sink Current = 10mA
◆ Every IO pin can be configured to enable wake-up function
◆ Built-in VDD/2 LCD bias voltage generator to provide maximum 4x10 dots LCD display
◆ Clock sources: IHRC, ILRC and EOSC (XTAL)
◆ For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast
◆ Eight levels of LVR reset ~ 4.0V, 3.5V, 3.0V, 2.75V, 2.5V, 2.2V, 2.0V, 1.8V
◆ Two selectable external interrupt pins by code option

CPU Features
