System block diagram

The AP8000 multipurpose programmer independently developed by Acroview Technology consists of three parts: host, base plate and adapter seat.

The host supports USB and NET connections, allowing multiple programmers to be networked, so as to control multiple programmers to programmer at the same time. The built-in chip safety protection circuit ensures that even if the chip is reversed or the short circuit caused by other reasons can be detected immediately and power off to ensure the safety of the chip and programmer. Embedded high-speed FPGA greatly accelerates data transmission and processing. There is an SD card slot on the back of the host computer. Put the project files produced by PC software into the root directory of the SD card and insert them into the slot. You can select, load, and execute the commands such as burning the project files by pressing the keys on the IC programmer to achieve the purpose of operating without the PC, greatly reducing the cost of PC hardware configuration, and quickly and conveniently matching the working environment.

The AP8000 makes the host more scalable by adding an adapter board to the backplane. At present, it has supported all devices produced by mainstream semiconductor manufacturers, including TI, ST, MicroChip, Atmel, Hynix, Macronix, Micron, Samsung, Toshiba, etc. Supported device types include NAND, NOR, MCU, CPLD, FPGA, EMMC, and other file formats including Intel Hex, Motorola S, Binary, POF, etc.
