SP16 Series programmer
ISP Power supply mode
When using ISP program, there are two power modes available for the target device. The power mode can
be set in the operating options of FlyPRO software.
⚫
Powered by programmer
Programmer supplies voltage to the target board at a supply voltage of 1.8V, 2.5V, 3.3V, or 5V (set in
operating options of FlyPRO software).
In this mode, if the programmer detects that the target board power supply already exists, it will give an
error message about the power supply conflict. Programmer has equipped with an overcurrent detection
function that limits the current to 250mA when power is supplied to the target board. Overcurrent
protection will occur when current exceeding this range. If the target board's operating current is greater
than 250mA, use the target board self-powered mode.
⚫
Target board self-powered
Programmer does not supply power to the target board in this mode.
SP16 programmer can support a target voltage range of 1.65V~5.5V. The signal driving voltage of the
ISP is automatically adjusted following the VCC voltage of the target board.
● ISP programming is relatively complicated to implement , you must be very familiar
with the circuit;
● The interference introduced by lead wire or other circuits on the circuit board may
cause ISP programming to fail. Please remove the device and use conventional IC
socket to program.
● For more detailed usage, please refer to the software help topic or the electronic
manual.
