CSR USB-SPI-S Burner Download Programmer Debugging Developments Tools 1.8V 3.3V New DIY leírása

1. Provide 3.3V and 1.8V dual power output, easy to use!
2. Increase SPI level switching function, support 3.3V and 1.8V (voltage version proprietary)!
3. Increase PTC current limiting protection, current limit 500MA, but then worry about the wrong connection, short circuit is not afraid (voltage version proprietary)!
4. The power supply process is cleaner, tantalum capacitors are used for decoupling, and two 220UF tantalum capacitors are built in (voltage-switched version is proprietary)!

Note: Regarding the SPI voltage specification, we all know that the IO port voltage of the CSR86XX series is 1.8V, so the SPI programming voltage also needs 1.8V. Of course, using 3.3V can also work, but if you use the SPI level of 3.3V, probably Will cause 5/1000 chip damage
Pin description:
1. MISO, CLK, CSB, and CLK are SPI writer interfaces. They are connected to the SPI interface of the CSR chip. The default SPI level is 1.8V! (Voltage Switching Edition Exclusive)
2. 3V3, 1V8 are reserved power output, can provide current less than 500MA (more than 500MA will automatically protect)! (Voltage Switching Edition Exclusive)
3. VS is the SPI voltage selection port. When VS is floating (with internal pull-), the SPI level is 1.8V. When VS is grounded, the SPI level is 3.3V! (Voltage Switching Edition Exclusive)
4. RST is the reset pin of the writer and the RST high signal resets the writer. (Normal Edition proprietary)
