CMSemicon, a famous chip design company in China, was invited to give a speech at the 15th Home Appliance Power and Intelligent Control Technology Innovation Seminar held in Shunde on June 19.

Mr. Pan An, a technical expert from CMSemicon, gave a detailed analysis of specific cases of kitchen and bath appliances and household appliances with the theme of "High-sensitive touch sensing technology and introduction of high-performance MCU products".

Mr. Pan An said, driven by the global consumption upgrade, the smart home appliance market is booming. As a breakthrough point of the new generation of home appliances upgrade, touch has gained more and more attention. CMSemicon follows the global technology development trend, launched CMS79FT series of capacitance-free touch products new portfolio.

CMS79FT capacitive-free touch series with high sensitivity and high immunity       

CMS79FT touch series has built-in high-speed sampling, high-precision adjustment circuitry, and highly sensitive features for proximity sensing and spaced touch functions. Combined with CMSemicon's patented touch scanning method, the possibility of solutions passing immunity certification tests will be enhanced to a greater extent, such as CS, EFT, ESD, RS immunity, etc.   

The series chip is also equipped with a complete touch application platform, where touch generation software can automatically generate library functions for a variety of application scenarios, including high sensitivity, high immunity, high responsiveness, and high water resistance. 

1 Characteristics of Induction cooker control solution         

CMS79FT738 for light control, CMS89F526 for main control. Equipped with capacitance-free high-sensitivity touch, the solution can realize a high-sensitivity slider, support waterproof function, with touch passing CS dynamic and static 10V test and CE, RE with small harassment. Chips used for displaying has an internal LED constant current module, simple circuit and a few peripheral components. The main control chip has built-in PPG, op-amp, multiple comparator, and simple peripheral circuit , supporting voltage surge and current surge detection at the same time,which provides double protection.

2 Characteristics of constant temperature machine control program                

CMS80F751x series for light control, CMS80F261x series for main control. Equipped with capacitance-free and high sensitive touch, large space and fast main frequency, it can realize touch, display and function three in one. With simple circuits, excellent CS, EFT, ESD immunity performance and endurance of high-voltage ignition shock, the perfect solution has abundant selections of supporting products.      

3 Characteristics of touch remote control program         

128-level disc slider touch, single key wake-up working current is about 10uA, built-in voltage reference and LVD module, and accurate detection of battery voltage.       

High-performance CMS80F series meet the intelligent needs of home appliance           

CMSemicon launches CMS80F series with 8051 core, which will help to realize the innovation and smart upgrade of home appliances with its advantages of high speed and large space.  

CMS80F series products are compatible with MCS51 instruction system, 1T instruction running clock, internal high-speed clock 48MHz, precision error control at 1%, the chip supports maximum external 16MHz high-speed crystal, high-speed and high-precision oscillation, which enables running of more instructions at the same time. Besides, the chip has 125KHz low-speed oscillation inside, which can directly provide clock information to the LCD module and reduce the power consumption of the module operation.  

The CMS80F series chip has a large space to meet the complex solution development needs in all aspects, with a maximum of 64K Flash, 256 bytes of internal registers and 4K bytes of external registers, and supports 0, 1, and 4K BOOT area configurations, which can meet the requirements of highly integrated product design. The BOOT area also effectively ensures the security and stability of the solution in board upgrade and remote upgrade, which is suitable for the development of smart home and home appliance solutions.

During the seminar, CMSemicon expressed its willingness to cooperate with the home appliance industry, expecting to promote the common growth of chip design companies and the home appliance industry with more integrated and feature-rich chip resources. CMSemicon is also confident to integrate multiple technology resources to promote the smart transformation and upgrade towards the intelligence of home appliance industry, and make joint efforts to build a leading home appliance brand in China market.
