The Kinetis KL0 MCU family is the entry point into the Kinetis L series based on the ARM Cortex -M0+ core. The KL0 ultra-low-power MCUs provide a bridge for 8-bit customers migrating into the Kinetis portfolio and is software and tool compatible with all other Kinetis L series devices.
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
