9.3.2.2

Dual Supply

The following tables detail the device power consumption when configured with a dual supply (VBAT

and 1.8V VDDCOREREG) and an externally supplied VDD12 for HSIC For additional information on

power connections, refer to Chapter 4, "Power Connections," on page 21.

9.3.2.2.1

USB UPSTREAM

Note: Typical values measured with VBAT = 4.2V, VDDCOREREG = 1.8V, VDD12 = 1.2V. Maximum

values measured with VBAT = 5.5V, VDDCOREREG = 2.0V, VDD12 = 1.32V.

9.3.2.2.2
