[Minimum system] STC32G12K128 core board V1.3

                                       To borrow a sentence from the STC official website: 2022, the first year of 32-bit 8051! The most important weapon of the country, the backbone of the country, all industrial regulations, strong anti-interference.
 
      Seeing this, the unique official website homepage has emerged in your mind. Yes, today we recommend a 2022 latest 32-bit 8051 core microcontroller: STC32G12K128 . In order to help everyone learn STC32 better, we specially designed this very exquisite core board with CH340 chip onboard. You can use it as soon as you get the development board. There is also an LED power light and a power-off reset button reserved on the board. , a user button, (multiple LED lights, you can choose and stick them on your own), and an external 24C02 memory, making your STC32 learning journey more convenient. Next, we will introduce some of the main features of the core board:
 
1. Chip characteristics
      STC32G series microcontroller is a 32-bit 8051 microcontroller targeting super anti-interference/ultra-low price/high speed/low power consumption. At the same operating frequency, the STC32G series microcontroller is The traditional 8051 microcontroller is about 70 times faster. It can be seen that the performance of STC's 32-bit microcontroller is not ordinary.
      The chip has a built-in high-precision R/C clock, which can be used without an external crystal oscillator. The main frequency is 33Mhz. The chip provides a wealth of digital peripherals, including 4 serial ports, 5 timers, 2 advanced PWM timers with dead zone control, IIC, SPI, USB, CAN, LIN interfaces and ultra-high-speed 12-bit ADC and comparison device to meet most design needs. What reasons do we have to reject this cost-effective 32-bit microcontroller launched by STC?
 
2 Onboard resource
main control chip: STC32G12K128, LQFP-48 patch package
Power supply connection: Use 1 Type C for power supply or connect to the computer for program download
Serial port download: Use the CH340N chip to communicate with the computer, no external downloader
LED display : One power indicator light and N status indicator
light button control: A power-off switch for chip cold start download, an independent button with interrupt function
Program expansion: Use the IIC interface to plug in an M24C20 EEPROM chip
pin header interface: isolate the chip Most of the pins are lead out and are compatible with other mainstream microcontroller core board pin arrangements.
Reference voltage source: Use the TL431 reference voltage source to provide a stable 2.5V reference voltage for the microcontroller.
      The onboard serial port download of this core board makes it easy to learn and debug. From learning the most basic input and output functions, serial communication, IIC communication, and important functions such as interrupts, timers, and PWM of the microcontroller, all can be done in this core Learn on the board.
