Changhong Successfully Produces Self-Developed Smart Control Chips for Refrigerators and Other Products

Changhong, a leading technology company based in China, has announced the successful production of its first batch of self-developed MCU (microcontroller unit) chips. These chips are installed in complete refrigerators and were rolled off the assembly line in Mianyang, China.

The MCU chips are based on the RISC-V architecture and feature a main frequency of 200MHz. They are the first in the industry to adopt the 40nm ULP (ultra-low power) process, which allows for high-precision ADC (analog-to-digital converter) technology and hardware and software security design. In addition, the chips incorporate key technologies such as algorithmic hardware and chemicalization.

This is a major achievement for Changhong, as it marks the first time the company has independently developed and produced MCU chips. These chips will be used to control and manage the operations of the refrigerators, ensuring their smooth and efficient functioning.

In the coming year, Changhong plans to install 10 million of its self-developed smart control chips in a variety of products, including refrigerators, air conditioners, washing machines, and refrigerator compressors. These chips, known as Microcontroller Units (MCUs) or Single Chip Microcomputers, are designed to reduce the frequency and specifications of the Central Process Unit (CPU) and integrate other features such as memory, counters, USB ports, and A/D conversion onto a single chip.

MCUs are widely used in a variety of applications, including mobile phones, PC peripherals, remote controls, automotive electronics, and industrial stepping motors. Changhong's smart control chips will not only be used in household appliances, but also in industrial control and energy management.
