Recently, ACROVIEW, a leader in the chip programming field, launched a significant version update of its programming software. Coinciding with the release of the new version, the company announced the addition of several compatible chip models, including the IM941KALBL automotive microcontroller developed by Immorta Microelectronics. This chip has successfully completed technical adaptation with ACROVIEW’s flagship AP8000 chip programming tool, significantly enhancing the chip compatibility and industry application range of the AP8000 series devices.
The IM941KALBL is a high-performance automotive-grade microcontroller based on the Cortex-M0+ core, specifically optimized for the technical requirements of automotive actuators and sensor control, to meet enhanced information security, rich connectivity, and functional safety requirements. This product integrates a Hardware Acceleration Unit (HAU) for three-phase brushless motors, supporting multiplication, division, trigonometric functions, and square root operations, greatly reducing the runtime of the motor FOC algorithm and improving motor control efficiency. Additionally, it has been significantly optimized for power consumption, with operating current and sleep current of only 12mA and 10µA, respectively, which is only 50% of similar products, to meet the stringent energy consumption requirements of new energy vehicles.

Overall Block Diagram
With its deep technical accumulation, ACROVIEW’s self-developed AP8000 universal programmer is regarded as a benchmark-level programming solution in the industry. This device supports flexible one-to-one and one-to-eight configurations, while providing both online and offline working modes. It has also developed dedicated programming solutions for eMMC and UFS storage chips, fully meeting the bare chip offline programming and on-board programming needs of Immorta Microelectronics’ entire series of chips. The AP8000 consists of three core modules: host, baseboard, and adapter, which endow it with excellent compatibility and expandability. As a universal programming platform, the AP8000 can not only adapt to various programmable chips on the market but also, due to its stable and efficient performance, serves as the core component of ACROVIEW’s secure programming device IPS5800S, efficiently handling large-scale chip programming tasks.
The AP8000 host features flexible connectivity options, equipped with USB and NET interfaces, allowing for easy networking of multiple programmers. Through the networking function, users can easily achieve synchronized control of multiple programmers, efficiently conducting parallel programming operations. In terms of safety, the host is equipped with an intelligent safety protection circuit that can monitor the chip placement status and circuit connection in real-time. If it detects abnormal conditions such as chip reverse insertion or short circuits, it will immediately trigger a power-off protection mechanism, fully safeguarding the safe operation of the chip and programmer. The host is internally equipped with a high-speed FPGA chip, significantly enhancing data transmission and processing efficiency, ensuring a smooth and efficient programming process. To enhance user convenience, the back of the host is equipped with an SD card slot, allowing users to store project files generated on the PC to the SD card and insert it into the slot. They can then complete file selection, loading, and programming operations through the physical buttons on the programmer, achieving independent operation without a PC. This design not only reduces dependence on computer hardware configurations but also simplifies the setup process of the working environment, significantly enhancing operational flexibility.
In terms of expandability and compatibility, the AP8000 adopts a modular design of baseboard and adapter, effectively expanding the functional boundaries of the host. Currently, this device has achieved support for all mainstream semiconductor manufacturers’ products, covering well-known brands such as SINOWEALTH, SemiDrive, Winbond, Holychip, and ESMT. 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 a one-stop, all-scenario chip programming solution.
