ATSAM4L8/L4/L2
6.2.2
Typical Powering Schematics
The ATSAM4L8/L4/L2 supports the Single supply mode from 1.68V to 3.6V. Depending on the
input voltage range and on the final application frequency, it is recommended to use the follow-
ing table in order to choose the most efficient power strategy
Figure 6-3. Efficient power strategy:
1.68V 1.80V

RUN mode
212µA/MHz @ FCPU=12MHz(PS1)
306µA/MHz @ FCPU= 48MHz(PS2)
100µA/MHz @ FCPU=12MHz(PS1) @ VVDDIN=3.3V

Note 1. The SAM4L boots in PS0 on RCSYS(115kHz), then the application must switch to
PS1 before running on higher frequency (<12MHz)
