WELLON
Tianjin Weilei Electronic Technology Co., Ltd. was established in 1998 and is a professional manufacturer that develops and produces universal programmers (burners). The first generation of products produced by the company is the three-socket plug-in six-in-one programming card L03A; the second generation product is the universal programmer VLP-1A/B/L/H that uses the computers parallel port communication; the third generation product is the more powerful VLP-3L that uses large-scale FPGA (online programmable gate array) and CPLD chips, and has system self-test, communication verification, and Chinese and English bilingual interfaces; the fourth generation product Wellon VP full series of programmers from low-end to high-end VP-28/38/48/58/68. This series of products is based on the third generation, using a new generation of FPGA chips. All products use USB interfaces, and high-end products use dual communication ports (with parallel communication interfaces at the same time). The programmer core uses a single-chip microcomputer with online upgrade (ISP) function, and the control software can automatically identify the level of the software version and automatically upgrade online. The fifth generation products are universal programmers VP-280/380/480/880, ISP programmers VP-ISP1/ISP2, and special programmers VP-PIC1. The performance is more integrated on the basis of the fourth generation, and the shape is more compact. ISP programmers have also changed the situation that domestic and international programmers of this type can only support dozens of chips from one manufacturer, and can support thousands of chips of different types from multiple manufacturers. It has transformed ISP programmers from dedicated programmers to general programmers. The sixth generation products are general programmers GP204/GP204S/GP-1/GP-2/VP-890/490/390/298/190, and ISP programmers VP-ISP10/ISP20. GP204, GP204S, GP-1, and GP-2 support offline programming mode, can run independently from a PC, are easy to operate, and are suitable for mass production.
