Acroview, a leader in chip programming, has announced an expansion of its compatible device portfolio alongside the release of its latest programming software. Its universal programming platform AP8000 now fully supports Aurasemi’s 3‑rail digital multi‑phase controller AU4683B‑QMR, providing customers with efficient and reliable professional programming solutions.

The AU4683B‑QMR is a 3‑rail digital multi‑phase controller that supports SVI3 and PMBus communication protocols. It can be used with Aurasemi’s AU4851 smart power stages to implement a multi‑phase voltage regulator (VR) solution with a minimum of external components.

The rail/phase combinations of the AU4683B‑QMR are flexibly configurable. The device provides on‑chip NVM for storing and restoring device configurations. Device configuration and fault parameters can be easily programmed or monitored via the PMBus interface. The AU4683B‑QMR can monitor and report output current by sensing the CS output of the AU4851 devices.

The AU4683B‑QMR features an easy‑to‑configure single‑power‑loop compensation for steady‑state and load‑transient conditions, enabling fast transient response to load steps with minimal output capacitance.

The AU4683B‑QMR also provides active current balancing and automatic phase shedding for improved thermal and efficiency performance. It includes input and output voltage monitoring, temperature monitoring with selectable protection features, and programmable load lines per rail.

Typical Application Block Diagram

Acroview’s independently developed AP8000 universal programmer has become a benchmark professional programming solution in the industry. The system supports flexible 1‑to‑1 and 1‑to‑8 configurations, offers both online and offline operating modes, and features dedicated programming solutions for memory chips such as eMMC and UFS. It fully covers the bare‑chip offline programming and on‑board programming needs for Aurasemi’s entire product portfolio. The AP8000 adopts an innovative modular design consisting of three core modules – mainframe, baseboard, and adapter – giving it outstanding compatibility and expandability. As a universal programming platform, it not only supports all types of programmable chips on the market but also delivers stable, high‑efficiency performance as a core component of Acroview’s automated high‑volume programming system IPS5800S, capable of handling large‑scale chip programming tasks to meet mass‑production requirements.

The AP8000 mainframe offers flexible connectivity, equipped with both USB and NET interfaces for easy networking of multiple programmers. Through networking, users can conveniently achieve synchronized control of multiple programmers for efficient parallel programming operations. In terms of security, the mainframe incorporates intelligent safety protection circuits that continuously monitor chip placement status and connection conditions. Upon detecting abnormal conditions such as reverse insertion or short circuits, it immediately triggers a power‑off protection mechanism to safeguard both the chip and the programmer. The mainframe is equipped with a high‑speed FPGA chip that significantly enhances data transfer and processing efficiency, ensuring a smooth and efficient programming process. For added convenience, an SD card slot is provided on the rear panel. Users can save project files generated on a PC to an SD card, insert it into the slot, and then use the physical buttons on the programmer to select, load, and execute programming operations – enabling standalone operation without a PC. This design not only reduces dependence on computer hardware but also simplifies workspace setup, greatly improving operational flexibility.

In terms of expandability and compatibility, the AP8000 adopts a modular combination of baseboard and adapter boards, effectively extending the mainframe’s capabilities. The system currently supports products from all major semiconductor manufacturers, including HAAWKING, XHSC, ZHIXIN, SAMSUNG, KIOXIA, and others. Its supported device types cover a wide range, including NAND, NOR, MCU, CPLD, FPGA, eMMC, and it is fully compatible with industry‑standard file formats such as Intel Hex, Motorola S, Binary, and POF, offering users a one‑stop, full‑scenario chip programming solution.
