Common Mode Filter. Connect 0.1 μF capacitor to GND
Power Power to on-chip regulator 3.0 V – 3.6 V. Requires 4.7 uF to GND at each VDD pin.
Power
Ground
LVCMOS I/O Power 1.8 V ±5% OR 3.0 V – 3.6 V. Requires 4.7 uF to GND at each VDDIO
pin.
DAP is the large metal contact at the bottom side, located at the center of the WQFN
package. Connect to the ground plane (GND) with at least 9 vias.
CAP
CAP
Decoupling capacitor connection for on-chip regulator. Requires a 4.7uF to GND at each
CAP pin.
Decoupling capacitor connection for on-chip regulator. Requires two 4.7uF to GND at this
CAP pin.
NC
GND
No connect. This pin may be left open or tied to any level.
Reserved. Tie to Ground.
(1) The VDD (VDD33 and VDDIO) supply ramp should be faster than 1.5 ms with a monotonic rise.
