Overall Block Diagram

With its deep technical accumulation, ACROVIEW Technology’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 operating modes, and has developed dedicated programming solutions for eMMC and UFS storage chips, fully meeting the bare chip offline programming and on-board programming needs for the entire series of Nation Technology chips. The AP8000 consists of three core modules: host, baseboard, and adapter, and this modular design provides excellent compatibility and expandability. As a universal programming platform, the AP8000 can adapt to various programmable chips on the market, and with its stable and efficient performance, it has become the core component of ACROVIEW’s bulk 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 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, significantly enhancing operational flexibility.

In terms of expandability and compatibility, the AP8000 adopts a modular design of baseboard and adapter board, effectively expanding the functional boundaries of the host. Currently, this device has achieved support for products from all major semiconductor manufacturers, covering well-known brands such as Renesas, Infineon, NXP, MPS, and Silicon Labs. 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.
