Overview: CYW43439
Single-Chip IEEE 802.11 b/g/n MAC/Baseband/ Radio with Integrated Bluetooth 5.2 Compliance The Cypress CYW43439 is a highly integrated single-chip solution and offers the lowest RBOM in the industry for smartphones, tablets, 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 5.0 compliance. In addition, it integrates a power amplifier (PA) that meets the output power 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.
The WLAN host interface supports gSPI and SDIO v2.0 modes, providing a raw data transfer rate up to 200 Mbps when operating in 4-bit mode at a 50 MHz bus frequency. An independent, high-speed UART is provided for the Bluetooth host interface.
Using advanced design techniques and process technology to reduce active and idle power, the CYW43439 is designed to address the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power management unit that simplifies the system power topology and allows for operation directly from a rechargeable mobile platform battery while maximizing battery life.
The CYW43439 implements the world’s most advanced Enhanced Collaborative Coexistence algorithms and hardware mechanisms, allowing for an extremely collaborative WLAN and Bluetooth coexistence.
