AT32UC3B
9.5.1 Power Consumtion for Different Sleep Modes
Notes: 1. Core frequency is generated from XIN0 using the PLL so that 140 MHz < f
PLL0
< 160 MHz and 10 MHz < f
XIN0
< 12 MHz.

Mode Conditions Typ. Unit
Active
- CPU running a recursive Fibonacci Algorithm from flash and clocked from
PLL0 at f MHz.
- Voltage regulator is on.
- XIN0: external clock. Xin1 Stopped. XIN32 stopped.
- All peripheral clocks activated with a division by 8.
- GPIOs are inactive with internal pull-up, JTAG unconnected with external pull-
up and Input pins are connected to GND
