Problems solved by technology

Several mainstream MCU suppliers currently on the market, such as Renesas Electronics, STMicroelectronics, Microchip (Atmel), and general-purpose ARM core emulators are not uniform, with different interfaces and large packages, occupying PCB board area; At the same time, due to the different occasions of MCU application, some are used in strong current control occasions, it is easy to connect to the computer through the emulator during the debugging process, damage the emulator and computer, and even hurt people in severe cases.
[0003] In addition, the existing emulator adapter board is only for a single series of MCU series, and cannot meet the debugging needs of various types of MCUs
Although the existing emulator adapter board also has protection, it only performs conversion or isolation, and the isolator adopts the optocoupler method, resulting in a large volume, which cannot fully meet the actual needs of users and protect the user's application system and personal Safety

Abstract

The invention relates to a universal conversion isolation circuit adaptive to MCU simulators of various models. The universal conversion isolation circuit comprises a first conversion isolation circuit, a second conversion isolation circuit and a third conversion isolation circuit, wherein the first conversion isolation circuit comprises a first simulator interface, a combined switch, a first isolation chipset and a first chip interface; the second conversion isolation circuit comprises a second simulator interface, a second isolation chipset and a second chip interface; and the third conversion isolation circuit comprises a third simulator interface, a third isolation chipset and a third chip interface. The capacitive coupling isolation chip is used, so that the problem that the simulator, the target product and even the PC are damaged due to voltage breakdown when a mains supply or high-voltage power supply product is simulated and debugged is solved. And moreover, a simulation interface is simplified, the region of the PCB is reduced, the PCB can be adapted to MCUs of various models, and the development efficiency is improved.
