描述 Description

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.

特性 Features

Ultra-Low-Power
• Next-generation 32-bit Cortex-M0+ core: 2x more CoreMark/mA than the closest 8/16-bitarchitecture
• Single-cycle fast I/O access port facilitates bit banging and software protocol emulation, keepingan 8-bit look and feel?
• Multiple flexible low-power modes, including new computer clocking option which reduces dynamicpower by placing peripherals in an asynchronous stop mode
• LPUART, SPI, I²C, FlexIO, ADC, DAC, LP timer and DMA support low-power modeoperation without waking up the core
