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

The host also supports USB and NET connections, enabling networking of multiple programmers to synchronize control of multiple programmers for programming operations. The built-in safety protection circuit can instantly detect abnormal situations such as reversed chip placement or short circuits and immediately cut off power, ensuring the safety of both the chip and the programmer. The host integrates a high-speed FPGA, significantly enhancing data transmission and processing speed. The back of the host features 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 commands without relying on a PC, which not only reduces PC hardware configuration costs but also facilitates the rapid establishment of a 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 CHIPONE, Eon, SIMCom, NORDIC, Cmsemicon, 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.
