3. TECHNICAL BRIEF
3.11. JTAG & ETM interface connector
< Fig 19. JTAG & ETM(Embedded Trace Module) interface connector >
In case of KS660 mass production, the JTAG & ETM interface connector will not be mount on board.
That is only for developing and software debugging purpose.( It will not be mounted on mass production
PCB)
3.12. Charging Circuit
ISL9221 accepts two power inputs, normally one from a USB (Universal Serial Bus) port and the other
from a desktop cradle.
The ISL9221 features 28V and 7V maximum voltages for the cradle and the USB inputs respectively.
Due to the 28V rating for the cradle input, low-cost, large output tolerance adapters can be used safely
.
