TH6503 USB Low-Speed Interface
Connecting the
TH6503 with a
Microcontroller
The TH6503 can be connected with any micro-
controller via a serial interface. The serial outputs
can be connected with any microcontroller ports.
The TH6503 out clock can be used to provide the
clock pulse supply to the microcontroller. The
reset output is low active and configured in an
open drain structure. For this reason the output
must be set at a defined level with external V
3.3
resistance.
