[原创] Cypress CYW4343W 2．4GHz WLAN单片解决方案

Cypress公司的CYW4343W是高度集成的单片解决方案,包括了ARM Cortex-M3 MCU,802.11 b/g/n MAC/基带/无线电,支持蓝牙4.1,以及功率放大器(PA),低噪音放大器(LNA),内部发送/接收(iTR)RF开关,WLAN主接口支持SDIO v2.0模式,数据传输速率高达200Mbps,单独的UART提供蓝牙主接口,支持单边带2.4 GHz IEEE 802.11b/g/n,主要用在可穿戴,物联网(IoT)网关,家庭自动化,以及各种其它手持设备.本文介绍了CYW4343W主要特性,系统框图,以及评估板BCM94343WWCD1_EVB主要特性,电路图和材料清单.

The Cypress CYW4343W is a highly integrated single-chip solution and offers the lowest RBOM in the industry for wearables, Internetof Things (IoT) gateways, home automation, and a wide range of other portable devices. The chip includes a 2.4 GHz WLAN IEEE 802.11 b/g/n MAC/baseband/radio and Bluetooth 4.1 support. In addition, it integrates a power amplifier (PA) that meets the outputpower requirements of most handheld systems, a low-noise amplifier (LNA) for best-in-class receiver sensitivity, and an internal transmit/receive (iTR) RF switch, further reducing the overall solution cost and printed circuit board area.
