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
