The Kinetis KL3x MCU family combines ultra-low power performance with a rich suite of analog, communication, timing, and control peripherals for consumer and industrial metering applications. Adds a segment LCD controller option to the Kinetis KL1x series Includes multiple, flexible low power modes including new compute mode that reduces dynamic power by placing peripherals in an asynchronous stop mode Provides a migration path to lower or higher performance and feature integration through compatibility with other Kinetis MCUs Backed by robust development tools and software
Ultra-Low-Power
- Next-generation 32-bit ARM Cortex™-M0+ core: 2x more CoreMark/mA than theclosest 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 modeoperation 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
- Segment LCD interface
- Capacitive touch-sensing inputs support up to 16 external electrodes and DMAdata 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 for universal or customized serial peripheral emulation
- High accuracy internal clock reference to support high performance communication
