Functional block diagram

The AP8000 universal programmer independently developed by Acroview Technology includes three parts: the host, the base plate, and the adapter seat.

The host supports USB and NET connections, allowing multiple Automatic Programmer to be networked to achieve the purpose of simultaneously controlling multiple programmers to burn at the same time. The built-in chip safety protection circuit ensures that even if the chip is reversed or a short circuit caused by other reasons can be detected immediately and the power will be cut 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 main unit. Put the project file produced by the PC software into the root directory of the SD card and insert it into the card slot. The project file can be selected, loaded, and burned through the buttons on the programmer. command, in order to achieve the purpose of operating without PC, which greatly reduces the cost of PC hardware configuration, and can be conveniently and quickly matched with the working environment.

AP8000 makes the mainframe more expandable by adding an adapter board to the backplane. Currently, it supports devices produced by all mainstream semiconductor manufacturers, including TI, ST, MicroChip, Atmel, Hynix, Macronix, Micron, Samsung, Toshiba, etc. Supported device types include NAND, NOR, MCU, CPLD, FPGA, EMMC, etc., and support file formats including Intel Hex, Motorola S, Binary, POF, etc.
