Arm® Cortex®-M0+|Ultra-Low Power Kinetis® KL2x USB MCU

動画の上をクリックすると再生されます。

The Kinetis^® KL2x is an ultra-low-power MCU family that adds a full-speed USB 2.0 On-the-Go (OTG) controller or a full-speed crystal-less USB 2.0 device controller in addition to the Kinetis KL1x series.

The Kinetis KL2x MCU family is compatible with Kinetis K20 MCUs (based on Arm^® Cortex®-M4), and with all other Kinetis KL1x, KL2x, KL3x, and KL4x series MCUs, providing a migration path to lower and higher performance and feature integration.

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, I^²C, 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
I^²S module for audio applications
FlexIO module supports a wide range of protocols including UART, I^²C, SPI, I^²S, PWM waveform generation
Smart card interface VMSIM (ISO7816-E)
