**PFB190**
General purpose series
Operating temperature : -40°C ~ 85°C
   
System Features
1. One hardware 16-bit timer
2. Two hardware 8-bit timers with PWM generation
3. Three hardware 11-bit PWM generators (PWMG0, PWMG1 & PWMG2)
4. Band-gap circuit to provide 1.20V reference voltage
5. Up to 13-channel 12-bit resolution ADC with one channel comes from internal band-gap reference voltage or 0.375*VDD
6. ADC reference high voltage: external input, internal VDD, Band-gap 1.20V, 2.2V, 2.4V, 2.68V
7. Max. 18 IO pins with optional pull-high & pull-low resistor
8. 18 IO pins Driving capability, Drive current = 30 / 60mA (Strong) and Sink current = 20mA
9. Every IO pin can be configured to enable wake-up function
10. Built-in VDD/2 LCD bias voltage generator to provide maximum 4x9 dots LCD display
11. Clock sources: IHRC, ILRC
12. One low-power clock (NILRC) wake-up stopsys regularly.
13. For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast
14. LVR range: 1.8V ~4.5V
15. External interrupt pins by code option
16. VCC input range: 4.3V ~ 20V
17. Programmable Charge Current Up to 500mA
18. Provide CC/CV operation with Thermal Regulation to Maximize Charge Rate Without Risk of Overheating
19. Sense has two main functions: Microphone Capacitor Sense (MCS) and Heating Resistor Sense (HRS)
  1. MCS supports capacitance range from 10pF to 24pF, and
  a. Typical detection noise = 21 LSB when Cm = 10pF
  b. Typical detection noise = 22 LSB when Cm = 24pF
  2. MCS supports MEMS-capacitor, and
  a. Typical detection noise = 20 LSB when CMEMS-capacitor = 1.4pF
  3. HRS supports resistor range from 0.5Ω to 1.5Ω, and 0.1Ω resistor variation detection
   
CPU Features
1. 8bit high performance RISC CPU
2. 93 powerful instructions
3. Most instructions are 1T execution cycle
4. Programmable stack pointer to provide 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
