EGP

 — — GND Ground – exposed ground pad(5)
(1) Do not supply external circuitry from this pin.
(2) VDDR pins 1, 2, and 34 must be tied together on the PCB.
(3) Output from internal DC/DC and LDO is trimmed to 1.5V.
(4) For more details, see the technical reference manual listed in Documentation Support.
(5) EGP is the only ground connection for the device. A good electrical connection to the device ground on the printed circuit board (PCB) is imperative for proper device operation.
(6) This pin is not connected to the die. In the LP-EM-CC2745R10-Q1 , LP-EM-CC2755P10 reference design, this pin is connected to ground to give better shielding on the antenna path.
