Cypress CYW4343W高度集成单片WLAN解决方案

Cypress公司的CYW4343W是高度集成的单片WLAN解决方案,包括2.4 GHz WLAN IEEE802.11 b/g/n MAC/基带/无线电,支持蓝牙4.1,集成了输出功率满足大多数手持设备要求的功率放大器(PA),具有最好接收器灵敏度的低噪音放大器(LNA)以及发送/接收(iTR)RF开关,从而进一步降低整个解决方案成本和PCB面积.主要用在可穿戴设备,物联网(IoT)网关,家庭自动化和其它手持设备.本文介绍了CYW4343W主要特性,支持WLAN和蓝牙的主要特性,框图和系统框图,以及其无线电功能框图,评估板CY8CKIT-062-WiFi-BT主要特性,Pioneer板和CY8CKIT-028-TFT板框图,电路图.

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 internaltransmit/receive (iTR) RF switch, further reducing the overall solution cost and printed circuit board area.

The WLAN host interface supports SDIO v2.0 mode, providing a raw data transfer rate up to 200 Mbps when operating in 4-bit modeat a 50 MHz bus frequency. An independent, high-speed UART is provided for the Bluetooth host interface.Using a
