PFS122
8bit MTP MCU with 12-bit R-Type ADC
1. 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: -20°C ~ 70°C
1.2. System Features
2KW MTP program memory (programming cycle at least 1,000 times)
128 Bytes data SRAM
One hardware 16-bit timer
Two hardware 8-bit timers with PWM generation
One hardware comparator
Bandgap circuit to provide 1.20V reference voltage
Up to 12-channel 12-bit resolution R-type* ADC with one channel comes from internal bandgap 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 is built in the PMS13x series.
Max. 14 IO pins with optional pull-high / pull-low resistor
Every IO pin can be configured to enable wake-up function
Clock sources: IHRC, ILRC and EOSC (XTAL)
For every wake-up enabled IO, two optional wake-up speed are supported: normal and fast
8 selectable levels of LVR reset from 1.8V to 4.5V
Two selectable external interrupt pins by code option
1.3. CPU Features
8-bit high performance RISC CPU
86 powerful instructions
Most instructions are 1T execution cycle
Programmable stack pointer to provide adjustable stack level
Direct and indirect addressing modes for data access. Data memories are available for use as an index
pointer of Indirect addressing mode
IO register space and memory space are independent
