*Note : VIO only appears on certain package options. If VIO is not present, the RST pullup can connect to VDD.
SUPPLY NET
Add ESD protection
diodes designed for
use with USB, such
as Littlefuse
SP0503BAHT or
equivalent.
Keep the USB shield ground
isolated from the device ground.
USB
Add decoupling/bypass
capacitors close to each
voltage supply pin.

Unused port pins should be left
floating, configured to push-pull
output, and driven high.
RESET SIGNAL
A 1-5 kohm pull-up resistor can
be connected to VIO* for added
noise immunity.
