Single Chip IEEE 802.11 b/g/n Network Controller SOC with Integrated Flash Memory

Atmel Corporation 

5. Power Management

5.1 Power Architecture

The Atmel WINC1500 device uses an innovative power architecture to eliminate the need for external regulators

and reduce the number of off-chip components. The architecture is shown in Figure 5-1.

The Power Management Unit (PMU) has a DC/DC Converter that converts VBATT to the 1.2V supply used by

the digital and RF/AMS blocks. The PA and eFuse are supplied by dedicated LDOs, and the VCO is supplied by

a separate LDO structure.

The power connections in Figure 5-1 provide a conceptual framework for understanding the WINC1500 power

architecture. Reference designs will be provided to demonstrate how to properly connect the supplies, including

proper isolation of the supplies used by the digital and RF/AMS blocks.
