Two independent power domains allow fine tuning of power consumption based on
needed features.
Each peripheral has its own clock divider for further power saving. These dividers help
reduce active power by 20 % to 30 %.
Brownout detect with separate thresholds for interrupt and forced reset.
On-chip power-on reset.
On-chip crystal oscillator with an operating range of 1 MHz to 25 MHz.
4 MHz internal RC oscillator trimmed to 1 % accuracy that can optionally be used as
the system clock. When used as the CPU clock, does not allow CAN and USB to run.
On-chip PLL allows CPU operation up to the maximum CPU rate without the need for
a high frequency crystal. May be run from the main oscillator, the internal RC oscillator,
or the RTC oscillator.
Boundary scan for simplified board testing.
Versatile pin function selections allow more possibilities for using on-chip peripheral
functions.
