## 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, ADC, DAC, LP timer and DMA support low-power mode operation without waking up the core

### Memory

* Up to 32 KB flash with 64 byte flash cache, up to 4 KB RAM

* Security circuitry to prevent unauthorized access to RAM and flash contents

* 8 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 -40C to +105C

* 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

* 12-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

* One 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

* I2C with DMA support, up to 100 kbps and compatible with SMBus V2 features

* LPUART and SPI with DMA support
