【CW32】Brushless DC motor driver board

Overview

Brushless DC motor driver board, using CW32F030C8T6.

The typec port only supplies power to the mcu. DC can power MCU and other devices at the same time.

The first version of the pcb uses a 40V.85A Mosfet and a three-phase 250V gate driver.

The second version of the pcb improvements uses a 30V.5A Mosfet and an easily soldered three-phase 250V gate driver.

The gate driver is 5v, and the 3.3v directly connected to the mcu is a bit doubtful.

But the data sheet of FD6288 says that the input logic is compatible with 3.3V/5V. Seeing that the big guys connect it like this, let’s try it first.

How to generate a process library-independent netlist from rtl code?
I am learning modelsim simulation and synopsys synthesis. Usually in synopsys we can use the following settings to generate netlist set SYNOPSYS_LIB /usr/synopsys/libraries/syn set target_library "$SY
Ask a question about SIM3OO
The protector made of 430 MCU and SIM300 module uses SMS to control the device. Now there is a problem. When the protector is powered off, the device will not execute the command when it is turned on,
Communication between fpga and arm9!
What are the specific methods for communication between fpga and arm9? I hope friends who have done it before can give me some advice! Thank you!
The hierarchical wordline structure can improve the SRAM read and write speed and reduce the circuit dynamic power consumption
The memory using hierarchical word line structure divides the entire storage array into several identical sub-arrays. Compared with the non-hierarchical word line structure, it requires multi-level wo
