Hot offer Ic chip PFS123 SOP-8 (Electronic Components Semiconductor Chip Microcontroller Supports IC BOM)

​   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: -20°C ~ 85°C

1.2. System Features

 3KW MTP program memory (programming cycle at least 1,000 times)

 256 Bytes data SRAM

 One hardware 16-bit timer

 Two hardware 8-bit timers with PWM generation

 One set triple 11bit SuLED (Super LED) PWM generators and timers

 One hardware comparator

 Bandgap circuit to provide 1.20V reference voltage

 Up to 14-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.

 ADC reference high voltage: external input, internal VDD

 Max. 18 IO pins with optional pull-high resistor, four of them with additional pull-low resistor

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

 Built-in VDD/2 LCD bias voltage generator to provide maximum 5x12 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

 8 selectable levels of LVR reset from 1.8V to 4.0V

 Two selectable external interrupt pins by code option

1.3. CPU Features

 8-bit high performance RISC CPU

 90 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 space and memory space are independent
