Thiết kế mạch nạp

Một điểm chú ý rằng, các loại mạch nạp bản chất cũng chỉ là tạo ra được mức điện áp phù hợp trên các chân VSS, VDD, MCLR, để đưa PIC vào chế độ nạp, và truyền dữ liệu trên chân PGD và PGC cho PIC. Các mạch nạp thiết kế khác nhau chủ yếu là do khả năng điều chỉnh, và ổn định điện áp, và cách thức truyền dữ liệu vào PIC. Vì vậy, sự khác biệt chủ yếu giữa các mạch nạp, nằm ở chỗ nó có thể hỗ trợ nạp cho nhiều dòng PIC khác nhau...
