Flexible Clock-Generation Unit (CGU0) able to control clock frequency of individual modules
  • 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.
Highly configurable system Power Management Unit (PMU)
  • clock control of individual modules.
  • allows minimization of system operating power consumption in any configuration.
Dual power supply
  • 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.
Other peripherals
  • One 10-bit ADC with 5.0 V measurement range and eight input channels with conversion times as low as 2.44 μs 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 μs 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.
