For production line which equipment can I utilize for programming the devices on circuit board?
I read AN-B-020 doc, here is described OTP burning procedure by smartsnippets and interface board.
Can I buy an ready Interface board or utilise J-Link programmer by segger with an external 6.8V supplied by a small circuit or I'm constrained to build an interface?
So the minimum numbers of pins for program the device is 6? (Vcc, GND, SWCLK, SWDIO, RESET, and one GPIO pin for BJT 6.8V control enable)
