System Peripherals

  • 32-Channel Event System

    • All channels can be connected to any event generator

    • All channels provide a pure asynchronous path

    • Twelve channels support synchronous and re-synchronous

  • Four Serial Communication Interfaces (SERCOM), Each Configurable to Operate as:
    • USART with full-duplex and single-wire half-duplex configuration
    • ISO7816
    • I2C up to 1 MHz (three SERCOMs support I2C)
    • LIN Commander/Responder
    • RS485
    • SPI with configurable inter-byte space
  • Four 16-bit Timers/Counters (TC), Each Configurable as:
    • 16-bit TC with two compare/capture channels
    • 8-bit TC with two compare/capture channels
    • 32-bit TC with two compare/capture channels
  • Two 24-bit Timer/Counters for Control (TCC) with Extended Functions:
    • Up to six compare channels with optional complementary output
    • Generation of synchronized Pulse Width Modulation (PWM) pattern across port pins
    • Deterministic fault protection, fast decay and configurable dead-time between complementary output
    • Dithering that increases resolution with up to 5 bits and reduces quantization error
  • One 16-bit Timer/Counters for Control (TCC) with Extended Functions:
    • Up to two compare channels with optional complementary output
  • 32-bit Real Time Counter (RTCC) with Clock/Calendar Function
  • Up to one Wake-up Pin with Tamper Detection and Debouncing Filter
  • Watchdog Timer (WDT) with Window Mode
  • Deadman Timer (DMT)
  • CRC-32 Generator
  • Frequency Meter (FREQM)
  • One Configurable Custom Logic (CCL)
  • One Temperature Sensor (Die Temperature)
  • 12-bit ADC SAR Module (ADC):
    • Up to Eight Analog Channels
    • Up to Two MSa/s conversion rate
    • Multiple trigger sources
    • Supports die temperature sensor built into RF-Analog (not an external ambient temperature sensor)
    • Two Analog Comparator (AC) with Window Compare Function or single Analog Comparator
    • One dedicated AC and second AC is shared with PMU Controller
