Products

◆◆ PFS123 ◆◆
General purpose series
Not supposed to use in AC RC step-down powered or high EFT requirement applications
Operating temperature : -20°C ~ 70°C
   
System Features
1. 3KW MTP program memory (programming cycle at least 1,000 times)
2. 256 Bytes data RAM
3. One hardware 16-bit timer
4. Two hardware 8-bit timers with PWM generator
5. One set triple 11bit SuLED (Super LED) PWM generators and timers
6. One hardware comparator
7. Band-gap circuit to provide 1.20V reference voltage
8. Up to 14-channel 12-bit resolution R-type*ADC with one channel comes from band gap voltage
  *Note: R-Type ADC means Resistive type ADC. Its linearity(INL & DNL), heat stability and power noise rejection would not be as good as the C-Type ADC which build in the PMS13x series
9. ADC reference high voltage: external input, internal VDD
10. Max. 18 IO pins with optional pull-high resistor, four of them with additional pull-low resistor
11. Every IO pin can be configured to enable wake-up function
12. Built-in VDD/2 LCD bias voltage generator to provide maximum 5x12 dots LCD displayy
13. Clock sources: IHRC, ILRC & EOSC (XTAL)
14. For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast
15. 16 selectable levels of LVR reset from 1.8V to 4.5V
16. Two external interrupt pins
   
CPU Features
1. 8-bit high performance RISC CPU
2. 88 powerful instructions
3. Most instructions are 1T execution cycle
4. Programmable stack pointer and adjustable stack level
5. Direct and indirect addressing modes for data access. Data memories are available for use as an index pointer of Indirect addressing mode
6. IO space and memory space are independent
