In the field of white goods, Silan Microelectronics can provide MCU-SC32F58/56 series products to meet the development needs of home appliances such as air conditioners, refrigerators, washing machines, range hoods, dishwashers, etc. The product adopts the ARM core + co-processing architecture. The co-processor supports co-processing functions such as MAC, DIV, CRC, etc., which can realize the calculation power optimization of motor FOC control. The Flash capacity covers 32K-256K. The product has rich peripheral functions and integrates multiple PWM, OPA, CMP, high-speed ADC, DMA, general timer, UART, SPI and co-processor (computing unit). It also has built-in op amps and comparators, which can effectively simplify peripheral circuits. In addition, in response to the different control requirements of various motor types and loads such as compressors, fans, and water pumps in home appliances, Silan Microelectronics has developed a complete motor control algorithm and a full set of solutions to serve the different needs of customers.

It is worth noting that Silan Microelectronics can provide matching power device products for the above solutions, which is also Silan Microelectronics' unique advantage. In order to help customers, Silan Microelectronics can also provide complete turnkey solutions and product packages for various applications, and provide a full set of design support. For example, in terms of general MCU, it can provide full technical support, including schematic design confirmation, bottom-level initialization engineering design, MCU module application routines, PCB design review, etc. For variable frequency MCU, it can provide complete solution support, including schematic design, algorithm software design, BOM table, PCB design and other full set of information and complete testing services.

In addition, Silan Microelectronics has increased its R&D investment in power semiconductor devices and high-voltage integrated circuit technology in recent years. It has achieved results in the four aspects of process platform construction, device structure research, device parameter model, and circuit architecture design verification, realizing the industrialization of high-voltage process platform and product development, and has launched multiple series of products on the market. Sales have increased year by year, and the market share has grown steadily. It has gradually developed into a domestic chip provider with the most discrete device product categories and the most complete specifications. The performance, reliability indicators, parameter consistency, etc. of the products can meet the packaging needs of international brand manufacturers.
