Instructions

FPU2 USB to JTAG/UART converter has FTDI FT2232 USB controller onboard. PORT A of FT2232 is configured as JTAG interface, PORT B as UART. Ports are connected to buffer IC’s. Buffer IC’s are needed to amplify driving current and to widen the supported voltage levels. Buffer IC’s are connected to 6 pin JTAG header J2, and 4 pin UART header J3, with 2.54mm pitch. Programmer is powered by 5v from USB, but still, external Vref voltages must be connected. Vref voltage must match JTAG/UART signals voltage. Programmer can work with Vref from 1.65v to 5.5v. This includes 1.8v, 2.5v, 3.3v and 5v standard signal levels. JTAG Vref can be different voltage level from UART Vref.
