Features

Ultra-Low-Power

  • Next-generation 32-bit Arm® Cortex®-M0+ core: 2x more CoreMark/mA than the closest 8/16-bit architecture
  • Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, keeping an 8-bit "look and feel"
  • Multiple flexible low-power modes, including new compute clocking option which reduces dynamic power by placing peripherals in an asynchronous stop mode
  • LPUART, SPI, I²C, FlexIO, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core

Memory

  • Up to 256 KB flash with 64 byte flash cache, up to 32 KB RAM
  • Security circuitry to prevent unauthorized access to RAM and flash contents
  • 16 KB ROM and built-in boot loader simplifies the effort to program MCU and allows for easy flash upgrades

Performance

  • Arm® Cortex®-M0+ core, 48 MHz core frequency over full voltage and temperature range (-40ºC to +105ºC)
  • Bit manipulation engine for improved bit handling of peripheral modules
  • Thumb instruction set combines high code density with 32-bit performance
  • Up to 4-ch. DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
  • Independent-clocked COP guards against clock skew or code runaway for fail-safe applications

Mixed-Signal

  • Up to 16-bit ADC with configurable resolution, sample time and conversion speed/power
  • Integrated temperature sensor
  • High-speed comparator with internal 6-bit DAC
  • 12-bit DAC with DMA support

Timing and Control

  • Two 6-ch. and one 2-ch. 16-bit low-power timer PWM modules with DMA support
  • 2-ch., 32-bit periodic interrupt timer provides time base for RTOS task schedule or trigger source for ADC conversion
  • Low-power timer allows operation in all power modes except for VLLS0
  • Real-time clock with calendar

Human-Machine Interface

  • Capacitive touch sense interface supports up to 16 external electrodes and DMA data transfer
  • GPIO with pin interrupt support, DMA request capability and other pin control options

Connectivity and Communications

  • Two I²C with DMA support, up to 1Mbps and compatible with SMBus V2 features
  • One LPUART and two UART with DMA support
  • Two SPI with DMA support
  • I²S module for audio applications
  • FlexIO module supports a wide range of protocols including UART, I²C, SPI, I²S, PWM waveform generation
  • FlexIO for universal or customized serial peripheral emulation
  • High accuracy internal clock reference to support high-performance communication
