Clock generation:
Clock output function that can reflect the main oscillator clock, IRC clock, RTC
clock, CPU clock, USB clock, or the watchdog timer clock.
On-chip crystal oscillator with an operating range of 1 MHz to 25 MHz.
12 MHz Internal RC oscillator (IRC) trimmed to 1% accuracy that can optionally be
used as a system clock.
An 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 or the
internal RC oscillator.
A second, dedicated PLL may be used for USB interface in order to allow added
flexibility for the Main PLL settings.
Versatile pin function selection feature allows many possibilities for using on-chip
peripheral functions.
Unique device serial number for identification purposes.
Single 3.3 V power supply (2.4 V to 3.6 V). Temperature range of
40 C to 85 C.
Available as LQFP208, TFBGA208, TFBGA180, and LQFP144 package.
