    ChipSourceTek-CST8F005X uses the 1T tiny 8051 core, this advanced kernel architecture makes the chip significantly improve the processing speed and efficiency. Its maximum operating frequency can reach 32MHz, and the fast clock frequency can ensure that the chip has a high response speed when dealing with complex tasks, and meet the application scenarios with high real-time requirements, such as fast data acquisition and processing in industrial automation control and high-speed data transmission in wireless communication.

    The chip is equipped with a variety of oscillators, among which the external high-speed crystal oscillator LOSC frequency is 32.768KHZ, which can provide a high-precision clock reference for the system. External high speed crystal oscillator HOSC frequency range of 2-32MHZ, can meet the needs of different frequency applications; Built-in RC oscillator LRC frequency is 32KHz, adjustable accuracy ±2%, suitable for relatively low clock accuracy requirements of the scene; The built-in RC oscillator has a HRC frequency of 32MHz and an adjustable accuracy of ±1%, which is excellent in cases where higher frequencies are required but there are certain requirements for accuracy.

Interrupt system

    ChipSourceTek-CST8F005X has a rich and powerful interrupt system. It has 9 effective interrupt sources and sets a two-level interrupt priority. This design enables the chip to allocate resources more reasonably when dealing with multiple interrupt requests, giving priority to important and urgent tasks, and improves the real-time and reliability of the system. At the same time, it also has 6 external interrupts, and these external interrupts can be configured in any pin input, and also supports the upper/lower/double edge trigger mode, which greatly enhances the chip's response ability to external events, so that it can flexibly respond to a variety of complex external environment changes.

timer

    The chip integrates three 16-bit universal timers 0/1/2, which are compatible with the standard 8051 and can be widely used in various timing tasks and waveform generation scenarios. For example, in motor control, PWM signal can be generated by timer to achieve accurate control of motor speed; In the communication protocol, the timer can be used to achieve accurate baud rate control and ensure the accuracy of data transmission.

IO port

    The chip has 26 general purpose GPIO ports and supports push-pull output mode. This allows the chip to directly drive many external devices, such as leds, relays, etc., without the need for additional drive circuits, simplifying hardware design and reducing costs. At the same time, the rich GPIO port also provides convenience for the connection with other external devices, which can easily realize the communication and interaction with a variety of devices such as sensors and displays.
