10.2 Device Connection and Layout Fundamentals

10.2.1 Reset
In order to meet the module power-on-reset requirements, an external 0.1 µF capacitor is required on the
nRESET pin during power ON. In addition, VDDS (Pin 46) and VDDS_PU (Pin 47) should be connected
together. If the reset signal is not based upon a power-on-reset and is derived from an external MCU, then the
external capacitor will not be needed and VDDS_PU (Pin 47) should be No Connect (NC). Please refer to
10-1 for the recommended circuit implementation and
10.2.2 Unused Pins
All unused pins can be left unconnected without the concern of having leakage current. Please refer to
7.3 for more details.

10.3 PCB Layout Guidelines

This section details the PCB guidelines to speed up the PCB design using the CC2652PSIP module. The
integrator of the CC2652PSIP modules must comply with the PCB layout recommendations described in
the following subsections to minimize the risk with regulatory certifications for the FCC, IC/ISED, ETSI/CE.
Moreover, TI recommends customers to follow the guidelines described in this section to achieve similar
performance to that obtained with the TI reference design.
10.3.1 General Layout Recommendations
Ensure that the following general layout recommendations are followed:
• Have a solid ground plane and ground vias under the module for stable system and thermal dissipation.
• Do not run signal traces underneath the module on a layer where the module is mounted.
