DC-CDI 16F628 v2.1

  Adaptation done by:   Characteristics Same software as AC-CDI v7 For single cyl. 1 advance curve. No alternator.   DOWNLOAD PIC 16F628A v2.1 DC-CDI Schematic PCB Board layout Partlist Eagle files   How does it works? Software is the same as AC-CDI version 7 Only the Hardware is different: High Voltage is no more coming from a charging coil, but it’s generating from the 12v battery. A UC3845 .


A great job fromĀ  Ivan A Gritskov from Russia.   Synoptic.   working. Ivan has used the Atmel DC-CDI originaly designed for a XT600, and modify it in order to fit a DRZ400S. He also used a Tiny2313 which has the same pinout a 89C2051, except the Reset pin which work in a opposite way. The software has been re-writed using BASIC-AVR and the advance curve has been changed .

DC-CDI 89C2051

A great job fromĀ  Thomas Schattat from Germany.   Characteristics. Adaptable to other single-cylinder bikes. Tuning of the advance curve (255 points). Software source available (.ASM). 7.500RPM max Compact & economic. Don’t need a alternator. Need a battery Working. Designed for a TT600R, this ignition is generating the High Voltage needed to load the capacitor. It doesn’t need a AC alternator. Circuit MC34063 “DC-DC converter control circuit” switch on/off .
