Features
Ultra-Low-Power
Next-generation 32-bit 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 computer 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 512KB flash, up to 128KB SRAM
Security circuitry to prevent unauthorized access to RAM and flash contents
Up to 32KB ROM and built-in bootloader simplifies the effort to program MCU and allows for easy flash upgrades
Performance
Cortex-M0+ core, 72MHz/96MHz 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 8-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
1.2 V and 2.1 V voltage references (Vref)
