KL2x: Kinetis® KL2x-72/96 MHz, USB Ultra-Low-Power Microcontrollers (MCUs) based on Arm® Cortex®-M0+ Core
Overview
Features
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)
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
- 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) with integrated USB low-voltage regulator supplies up to 120 mA off-chip at 3.3 volts to power external components from 5-volts input or USB 2.0 Device (full-speed) with clock recovery feature without the need of external crystal
- FlexIO for universal or customized serial peripheral emulation
- High accuracy internal clock reference to support high-performance communication
- Up to 3 I2C with DMA support, up to 1Mbps and compatible with SMBus V2 features
- Up to 3 LPUART with DMA support
- Up to 3 SPI with DMA support
- I²S module for audio applications
- FlexIO module supports a wide range of protocols including UART, I²C, SPI, I²S, PWM waveform generation
- Smart card interface VMSIM (ISO7816-E)
