One 10-bit ADC with 5.0 V measurement range and eight input channels with
conversion times as low as 2.44 s per channel
Two 10-bit ADCs, 8-channels each, with 3.3 V measurement range provide an
additional 16 analog inputs with conversion times as low as 2.44 s per channel.
Each channel provides a compare function to minimize interrupts.
Multiple trigger-start option for all ADCs: timer, PWM, other ADC, and external
signal input
Four 32-bit timers each containing four capture-and-compare registers linked to
I/Os
Four six-channel PWMs (Pulse-Width Modulators) with capture and trap
functionality
Two dedicated 32-bit timers to schedule and synchronize PWM and ADC
Quadrature encoder interface that can monitor one external quadrature encoder
32-bit watchdog with timer change protection, running on safe clock
On-chip very low-power ring oscillator; fixed frequency of 0.4 MHz; always on to
provide a Safe_Clock source for system monitoring
On-chip crystal oscillator with a recommended operating range from 10 MHz to
25 MHz. PLL input range 10 MHz to 25 MHz.
On-chip PLL allows CPU operation up to a maximum CPU rate of 125 MHz
Generation of up to 11 base clocks
Seven fractional dividers
clock control of individual modules
allows minimization of system operating power consumption in any configuration
CPU operating voltage: 1.8 V  5 %
I/O operating voltage: 2.7 V to 3.6 V; inputs tolerant up to 5.5 V
