Home appliance chip programming solution

Based on the product characteristics of home appliance brands such as Haier, Midea, Panasonic, Joyoung, and Supor, Xeltek Programmers have developed customized programming solutions covering the full range of white goods and kitchen appliances. These solutions are compatible with core chips including main control, frequency conversion, touch control, and power management chips, perfectly meeting the requirements of mass production and intelligent upgrading of home appliances.

Core Adaptation Scenarios and Alignment with Customer Requirements

Core Control Scenario for White Goods (Haier, Midea, Panasonic)Compatible with main control MCUs and frequency conversion control chips used in white goods such as air conditioners, refrigerators, and washing machines, covering mainstream models including Midea Meiren MR88F001 series, Haier special-purpose driver chips, and Panasonic frequency conversion control chips. Supporting multi-protocol adaptation of SPI and I2C, it optimizes low-power timing parameters to meet the requirements of long-term stable operation of home appliances, and adapts to the demand for large-batch parallel programming on production lines.

Intelligent Control Scenario for Kitchen Appliances (Joyoung, Supor)Targeting kitchen appliances such as rice cookers, induction cookers, and wall breakers, it is compatible with touch control chips, temperature control chips, and safety monitoring chips. Supporting common packages like QFN and SOP, it is equipped with ESD protection function to prevent damage to precision chips during programming, while adapting to the production feature of rapid switching between multiple program versions of kitchen appliances.

Intelligent Upgrading Scenario for Home Appliances (Applicable to All Brands)Compatible with chips of smart home appliances with networking functions, supporting the supporting programming of WiFi/Bluetooth modules, and compatible with firmware encryption and OTA upgrade pre-configuration. It can complete program writing, parameter calibration, and function verification in one go, meeting the upgrading needs of home appliance intellectualization and networking, and adapting to the production scenario of mixed-model production on the same line.

Core Advantages of the Solution

• Full-Range Chip Compatibility: Boasting a device library of over 80,000 components, it supports mainstream 8-bit/32-bit MCUs, frequency conversion chips, and touch control chips in the home appliance industry, including core models such as the 51 series and ARM Cortex-M series.

• Mass Production Efficiency Assurance: Supporting multi-station parallel programming, with short overall programming time per chip. Combined with automated production line interfaces, it greatly improves the large-scale production rhythm of brands like Haier and Midea.

• High-Reliability Data Assurance: Built-in dual verification algorithms of ECC and CRC-32 to eliminate incorrect programming and missing programming. The programming failure rate is controlled at an extremely low level, complying with the high-reliability standards of the home appliance industry.

• Flexible Adaptation Features: Supporting dual modes of offline programming and online upgrading, it adapts to production line mass production, firmware iteration, and rework inspection scenarios, and can quickly switch programming parameters for different home appliance models.

Solution Value

With high compatibility, high stability, and high efficiency as its core, the solution accurately matches the production characteristics of the home appliance industry, such as large-scale mass production, mixed-model production on the same line, and high reliability. It helps customers such as Haier and Midea simplify the programming process, reduce the risk of human errors, and improve the ex-factory yield of products. Meanwhile, it supports the upgrading needs of home appliance intellectualization and energy conservation, facilitating the rapid launch of products into the market.
