3 Implementation Recommendations
This section describes how to implement features related to the Power Management
of the Wireless CPUs.
3.1 Applying power on VCC
Main power is applied to VCC using GND as reference. The source can be any of the
following listed types:
• Li-Ion battery (3.7V nominal)
• AC/DC power supply (3.6V nominal)
• DC/DC power supply (3.6V nominal)
Reference designs for AC/DC and DC/DC supplies can be found in Appendix A and B
at the end of this document.
