As a leader in chip programming, Acroview, while releasing a new version of its programming software, officially announced further expansion of its compatible chip model coverage. The company's core product, the universal programming platform AP8000, has now achieved full compatibility with XHSC's 32-bit microcontroller HC32M458KCT.

The HC32M458KCT is a fully domestically produced high-performance dual-motor inverter control chip launched by XHSC. It is positioned as the industry's first high-performance inverter MCU for air-conditioner outdoor units with a fully domestic supply chain. Based on the Cortex-M4 core with a 200 MHz main frequency, it focuses on coordinated control of dual motors and PFC, with strong anti-interference capability and low failure rate. It integrates high-precision HRC, high-speed ADC, OPA, and other motor-specific units, reducing peripheral BOM cost.

Acroview's self-developed AP8000 universal programmer has become a professional programming solution with benchmark significance in the industry. The device supports flexible 1-to-1 and 1-to-8 configurations and provides both online and offline operating modes. It has especially developed dedicated programming solutions for memory chips such as eMMC and UFS, and can fully cover the bare-chip offline programming and on-board programming needs of XHSC's full series of chips. AP8000 adopts an innovative modular design with three core modules: main unit, baseboard, and adapter socket, giving the device excellent compatibility and scalability. As a universal programming platform, it can not only adapt to various programmable chips on the market, but also, with stable and efficient performance, serves as a core component of Acroview's automated batch programming equipment IPS5800S, efficiently handling large-scale chip programming tasks and meeting mass-production requirements.

The AP8000 main unit offers flexible connection methods and is equipped with both USB and NET interfaces, enabling convenient networking of multiple programmers. Through the networking function, users can easily achieve synchronous control of multiple programmers and efficiently carry out parallel programming operations. In terms of security, the main unit has a built-in intelligent safety protection circuit that can monitor chip placement status and circuit connection conditions in real time. Once abnormalities such as reverse chip insertion or short circuits are detected, it will immediately trigger a power-off protection mechanism, comprehensively safeguarding the safe operation of chips and the programmer. The main unit is equipped with a high-speed FPGA chip, greatly improving data transmission and processing efficiency and ensuring a smooth and efficient programming process. To enhance ease of use, the back of the main unit is provided with an SD card slot. Users only need to store project files generated on a PC to an SD card and insert it into the slot, then use the physical buttons on the programmer to complete file selection, loading, and programming, enabling standalone operation without a PC. This design not only reduces dependence on computer hardware configuration but also simplifies the work environment setup process and significantly improves operational flexibility.

In terms of scalability and compatibility, AP8000 adopts a modular combination design of baseboard and adapter boards, effectively expanding the functional boundaries of the main unit. At present, the device supports products from all mainstream semiconductor manufacturers, covering well-known brands such as SK hynix, Micron, SANDISK, ASR, and Kingston. It supports a wide range of device types, including NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and is fully compatible with various industry-standard file formats such as Intel Hex, Motorola S, Binary, and POF, providing users with one-stop, full-scenario chip programming solutions.
