The chip programming leader Anko Technology recently announced the latest iteration of its programming software, along with a series of newly compatible chip models. In this update, the mixed-signal chip OB6628LGQ launched by OnBright has been supported by Anko’s programming device AP8000.

OB6628LGQ is a dedicated three-phase brushless DC (BLDC)/permanent magnet synchronous motor (PMSM) controller system on chip (SoC). This integrated circuit is optimized for low-cost, high-efficiency drive circuits in application requirements.

With simple components, a control circuit for brushless DC (BLDC)/permanent magnet synchronous motor (PMSM) with current and speed loops can be easily constructed.

OB6628LGQ integrates a Cortex-M0 microcontroller (MCU), three-phase level-shifting drivers, a 5V low-dropout linear regulator (LDO), and a motor drive current protection comparator.

Internal Block Diagram

The AP8000 universal programmer developed by Anko Technology is a powerful programming solution that supports both online and offline versions in one-to-one and one-to-eight configurations, while also providing dedicated programming solutions for eMMC and UFS, fully meeting the bare chip (offline) and on-board programming needs of the OnBright series of chip models. The AP8000 consists of three core components: the host, the baseboard, and the adapter, serving as an industry-leading universal programming platform that not only meets the programming needs of various programmable chips on the market but also serves as the core programming platform for Anko’s automated secure programming IPS5800S, efficiently supporting the execution of large-scale programming tasks.

The host supports both USB and NET connections, enabling networking of multiple programmers to synchronize control multiple programmers for programming operations. The built-in safety protection circuit can instantly detect abnormal conditions such as reversed chip placement or short circuits, and immediately cut off power to ensure the safety of the chip and programmer. The host integrates a high-speed FPGA, significantly enhancing data transmission and processing speed. The back of the host is equipped with an SD card slot, allowing users to save project files generated by PC software to the root directory of the SD card and insert it into the slot. By using the button on the programmer, users can select, load, and execute programming instructions without relying on a PC, which not only reduces the hardware configuration cost of the PC but also facilitates the rapid construction of the working environment.

The AP8000 enhances the host’s expansion capabilities through the combination design of the baseboard and adapter, currently supporting products from all major semiconductor manufacturers, including Infineon, ST, NXP, MPS, MICROCHIP, and others. The types of devices supported include NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and it is compatible with various file formats such as Intel Hex, Motorola S, Binary, POF, etc.
