Out of curiousity, are there any microcontrollers which are available with and without debugging capabilities?
I'm asking because I assume that the debugger is not a simple 'peripheral' in terms of e.g. silicon space; I figure it would be much more complex than an SPI, I²C or ADC peripheral.
If that is true, would it make sense to provide 'development' devices with integrated debugging and 'production' devices for mass production? Could the latter be made cheaper because of the omitted functionality?
Are there µC's for which those two variants exist?
