(1) Resistors necessary in D+ and D-line control
(2) 48MHz and 480MHz PLL
(3) 3.3V → 1.5V regulator
Importing the external devices
This controller is equipped with the external devices listed below. Also, as the VBUS pin has 5V-tolerant, the user
system can connect the VBUS signal directly to this controller.
The following D+ and D- resistors necessary for USB communication are installed:
Operations can be executed by selecting one of the three types of external clocks (12MHz/24MHz/48MHz).
1.5V core power is generated in this controller. In the system where a 3.3V interface power is used, this controller
can be operated on a single power supply.
