STC offline download U disk version of U7 support for 3.3V and 5V automatic / offline download

stand tube or reel

Download profiles

1. Download the program automatically restart the mcu.
2. Offline download, can be away from the computer to download, as long as the want to download the program is downloaded to the download is in, you can with led away from the computer to the target chip Download
3. Site upgrade: particularly suitable to the scene to upgrade the engineers, no longer carry the computer to the scene to upgrade, the download is powered by the target circuit board,Don't need the etra power, of course, no target board power supply, charging treasure can also be, tinkling se;
4. Batch burner: factory batch download, Download save manual recording button interface, start, GND if connected with the push of a button;
    
5. At the same time with 3.3V and 5V output, 3.3V and 5V microcontroller can be used;
6. Completely replace the official STC U8-MIN offline Download;
7. Support all STC series microcontroller, both 5V and 3.3V are all!

Connection port description

GND: STC: GND pin connected to the MCU;

And TD: meetSTCSingle chip microcomputerP30Pin;

5, RD: meetSTCSingle chip microcomputerP31Pin;

7,5V0STC MCU VCC pin; (Is limited to the 5V microcontroller, can be input and output 5V)

9, 3V3: STC MCU VCC pin (;Only limited to the 3.3V microcontroller, can only be output 3.3V)

GND: ground of the sorting machine;

Fourth, START: sorting machine start signal (active low);Can be repeated to download the button (the other end of the GND)

6, EOT: complete signal separator (active low);

S, OK:Successful signal to the sorting machine;(active low)

The ERROR:, after sorting machine error signal (active low);
