Shulou(Shulou.com)11/24 Report--

CTOnews.com December 28 news, today, carrying Changhong independent research and development of intelligent control MCU chip of the first batch of refrigerator machine in China (Mianyang) Science and Technology City successfully offline.

According to reports, the MCU chip is based on the RISC-V core and the main frequency reaches 200MHz. It uses 40nm ULP ultra-low power process design for the first time in the industry to achieve high-precision ADC (analog-to-digital converter), software and hardware security design, algorithm hardware and other key technology research and breakthrough.

According to Changhong, in the coming year, the intelligent control chip plans to install 1000 million pieces in refrigerators, air conditioners, washing machines, refrigerator compressors and other products. At the same time, the chip will be widely used in industrial control, energy management and other fields.

CTOnews.com learned that the micro control unit (Microcontroller Unit;MCU), also known as the single chip microcomputer (Single Chip Microcomputer) or single chip microcomputer, is the central processing unit (Central Process Unit). The frequency and specification of CPU are appropriately reduced, and the peripheral interfaces such as memory (memory), counter (Timer), USB, A / D conversion, UART, PLC, DMA, and even LCD driver circuit are integrated on a single chip to form a chip-level computer to do different combination control for different applications. MCU can be seen in mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepper motors, robot arm control, and so on.
