[原创] NXP KW41Z 2．4GHz双模式无线MCU开发方案

NXP公司的KinetisKW41Z是基于ARM® Cortex®-M0+核的2.4GHz双模式BLE和802.15.4无线微控制器(MCU),支持同时运行Bluetooth®低能耗(BLE) v4.2和基于IEEE® 802.15.4的Thread协议,具备足够存储容量(512 KB闪存和128 KB SRAM）,可运行所有应用程序,是经济高效的解决方案,并降低了设计成本和设计复杂性,减小了产品的整体尺寸.可用在物联网设备之间安全可靠通信.本文介绍了KW41Z主要特性,框图,FRDM-KW41Z Freedom开发板主要特性,框图和电路图.

The KW41Z/31Z/21Z (called KW41Z throughout this document) is an ultra lowpower,highly integrated single-chip device that enables Bluetooth low energy (BLE),Generic FSK (at 250, 500 and 1000 kbps) or IEEE Standard 802.15.4 RF connectivityfor portable, extremely low-power embedded systems. Applications include portablehealth care devices, wearable sports and fitness devices, AV remote controls,computer keyboards and mice, gaming controllers, access control, security systems,smart energy and home area networks.

The KW41Z SoC integrates a radio transceiver operating in the 2.36 GHz to 2.48 GHz　range supporting a range of FSK/GFSK and O-QPSK modulations, an ARM Cortex-M0+ CPU, up to 512 KB Flash and up to 128 KB SRAM, BLE Link Layer hardware,802.15.4 packet processor hardware．
