After the large-scale popularization of Type-C interface,the design of combining power and data puts forward higher requirements for the control chip.CH32X035 is an industrial-grade microcontroller based on highland barley RISC-V core,which integrates USB and PD PHY on chip.With one chip,fast charging protocol communication and device control can be completed at the same time,and the number of peripheral devices is obviously reduced.
First,Kernel and Computing Power
The domestic MCU adopts RISC-V4C processor,the highest frequency is 48MHz,and it supports one-cycle multiplication and hardware division.20KB SRAM is matched with 65KB Flash,so there is a margin between running protocol stack and user logic.
Second,wide voltage power supply and low power consumption
The power supply range of domestic MCU single chip microcomputer system is 2~5.5V,and the wide voltage design is convenient for various power access methods;It has three low-power consumption modes:sleep,stop and standby.With power-on reset and programmable voltage monitor,the reliability of power supply is guaranteed.
Third,USB and PD capabilities
MCU MCU has built-in USB2.0 full-speed controller and PHY,which supports the dual roles of Host and Device.At the same time,integrating USB PD with Type-C controller and PHY can undertake the fast charging function of PDUSB and Type-C,which is the core of the"data+power in one"scheme.
Fourth,simulation and touch resources
Provide 2 sets of OPA operational amplifiers(used as PGA),3 sets of CMP voltage comparators,multiple channels of 12-bit ADC and 14 channels of TouchKey detection;The programmable protocol I/O controller PIOC makes the pin function definition more flexible.
In the selection of domestic MCU,CH32X035 reduces the area of peripheral devices and boards with high integration,which is suitable for the volume and cost-sensitive applications such as Type-C fast charging,USB HUB,power tools and small household appliances.We are the first-class agent of Qin Heng,the original manufacturer of domestic MCU CH32X035.If you have any domestic MCU products or selection needs,please feel free to call us.
