4.10.1 Overview

The IC has four power domains:

  1. VS – Unregulated battery voltage input
  2. DVCC – Internally regulated digital supply voltage. Typical value is 1.35V.
  3. AVCC – Internally regulated RF front end and XTO supply. Typical value is 1.85V.
  4. VS_SPDT – To achieve full PCB and RF application compatibility with the ATA8510/15. In the ATA8210/15 this supply is always switched OFF and connected externally to ground.

Operate the ATA8210/15 from VS = 1.9-3.6V (3V application).
