NXP BLE 芯片简介
NXP BLE 芯片简介
NXP 的BLE芯片目前包括QN902x 和 Kinetis KW3x两大系列，NXP BLE Solution 主页为：Bluetooth Smart|Bluetooth Low Energy|BLE|恩智浦
1）QN902x系列包括QN9020和QN9021，他们主要区别是封装不同，QN9020为QFN48（6x6mm），QN9021为QFN32（5x5mm）。QN902x的主要技术参数如下：
》Cortex- M0内核
》支持BLE4.1
》96Kb ROM，128Kb SPI Flash ，64Kb RAM 。代码在RAM中执行
》最高工作频率32Mhz
》输出功率：-20~4dBm；接收灵敏度：-95dBm
》功耗：接收电流：9.25mA，发送电流：8.8mA ，sleep mode：3uA
该芯片的datasheet：http://cache.nxp.com/documents/data_sheet/QN902X.pdf?fpsp=1&WT_TYPE=Data%20Sheets&WT_VENDOR=FREESCAL...
官方的评估板为QN9020DK，链接为：高度可扩展的QN9020应用开发平台|恩智浦
另外一第三方公司也有一套开发板，可用来评估QN902x芯片，其连接地址为：FireBLE - Firefly wiki
2）KW3x，包括KW30和KW31两个系列，KW30 具体信息可以参考：KW30Z|Kinetis Bluetooth Low Energy MCU|恩智浦
KW31具体信息可以参考：KW31ZlKinetis BLE无线MCU|恩智浦
随便说下，NXP还有一个KW4x系列，该芯片可以同时支持Zigbee和BLE，它包括KW40和KW41，主页分别为：KW40Z|Kinetis BLE & 802.15.4无线MCU|恩智浦
