Datasheet

Features
Ultra Low Power
• Next-generation 32-bit ARM Cortex-M0+
core. Two times more CoreMark/mA than the
closest 8/16-bit architecture. Single-cycle fast
I/O access port facilitates bit banging and
software protocol emulation, maintaining an
8-bit “look and feel.”
• Multiple flexible low-power modes, including
new compute mode which reduces
dynamic power by placing peripherals in an
asynchronous stop mode
• LPUART, SPI, I
2
C, ADC, DAC, LP timer and
DMA support low-power mode operation
without waking up the core
Flash and SRAM
• 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
Performance
• ARM Cortex-M0+ core, 48 MHz core
frequency over full voltage and temperature
range (–40 ˚C +105 ˚C)
• 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.
Single or differential input mode operation in
order to achieve improved noise rejection
• High-speed comparator with internal
6-bit DAC
• 12-bit DAC with DMA support
Timing and Control
• One 6-ch. and two 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
HMI
• 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
• USB 2.0 On-The-Go (Full Speed). Integrated
USB low-voltage regulator supplies up to
120 mA off chip at 3.3 volts to power
external components from 5-volt input
• Two I
2
C with DMA support, up to 400 Kb/s
and compatible with SMBus V2 features
• One LPUART and two UART with
DMA support
• Two SPI with DMA support
• I
2
