STC32G12K128-351-L0FP48

32-bit 8051 core single-chip microcomputer chip

Product Introduction

       The STC32G series of single-chip microcontrollers do not require external vibration or external reset. They are 32-bit 8051 single-chip microcontrollers that aim for super strong anti-interference, ultra-low cost, high speed and low power consumption. Under the same operating frequency, the STC32G series of single-chip microcontrollers are approximately 70 times faster than the traditional 8051.

       The STC32G series of microcontrollers is a single-clock (1T) microcontroller produced by STC. It is a new generation of 32-bit 8051 microcontrollers featuring wide voltage, high speed, high reliability, low power consumption, strong anti-static and strong anti-interference capabilities. Super encryption.

        MCU from the integration of high precision in the RC clock + (plus or minus 0.3%, room temperature 25 ℃), 1.38% ~ + 1.42% temperature wave (- 40 ℃ ~ + 85 ℃),Temperature drift: 0.88% to +1.05% (-20℃ to +65℃). When programming the ISP, a wide range of 4MHz to 33MHz can be set, which can completely eliminate the need for expensive external vibration and external reset circuits (the internal highly reliable reset circuit is integrated, and the 4-level reset gate voltage can be selected during ISP programming).

        There are four optional clock sources inside the MCU: an internal high-precision IRC clock (the frequency can be adjusted during ISP programming), an internal 32KHz low-speed IRC, an external 4M to 33M pin oscillator or external clock signal, and an internal PLL output clock. In the user code, the clock source can be freely selected. After the clock source is chosen, it can be further divided by an 8-bit frequency divider before the clock signal is provided to the CPU and various peripheral devices (such as timers, serial ports, SPI, etc.).

        The MCU offers two low-power modes :IDLE mode and STOP mode. In IDLE mode, the MCU stops providing a clock to the CPU. The CPU has no clock and stops executing instructions, but all peripheral devices are still in operation. At this time, the power consumption is approximately 1.3mA(operating frequency of 6MHz). The STOP mode, also known as the master clock stop-vibration mode, is the traditional power-off mode/power outage mode/shutdown mode. At this time, the CPU and all peripheral devices stop working, and the power consumption can be reduced to below 1uA.

       The MCU offers a rich array of digital peripherals (4 serial ports, 5 timers, and 2 sets of complementary/symmetrical/output for three-phase motor control).

The 16-bit advanced PWM timer with dead zone control signal and I2C, SPI, USB, CAN, LIN interfaces, as well as analog peripherals (ultra-high-speed 12-bit ADC, comparator) can meet the design requirements of a wide range of users.

       The STC32G series microcontrollers have 268 powerful instructions, including 32-bit addition and subtraction instructions and 16-bit multiplication and division instructions. The hardware has been expanded with a 32-bit hardware multiplication and division unit MDU32(including 32-bit division by 32-bit and 32-bit flexible division by 32-bit).

        The STC32G series of microcontrollers integrates enhanced dual data Pointers internally. Through program control, the functions of automatic increment or decrement of data Pointers and automatic switching between two sets of digital Pointers can be achieved.
