CYW4339

PRELIMINARY CYW4339 Single-Chip 5G WiFi IEEE 802.11ac MAC/ Baseband/Radio with Integrated Bluetooth 4.1 General Description The Cypress® CYW4339 single-chip device provides the highest level of integration for Internet of Things and handheld wireless system with integrated single-stream IEEE 802.11ac MAC/baseband/radio and Bluetooth 4.1. In IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–MCS9 (up to 256 QAM) in 20 MHz, 40 MHz, and 80 MHz channels for data rates up to 433.3 Mbps. In addition, all the rates specified in IEEE 802.11a/b/g/n are supported. Included on-chip are 2.4 GHz and 5 GHz transmit amplifiers, and receive low-noise amplifiers. Optional external PAs, LNAs, and antenna diversity are also supported. For the WLAN section, several alternative host interface options are included: an SDIO v3.0 interface that can operate in 4b or 1b and a PCIe Gen1 interface (3.0 compliant). For the Bluetooth section, host interface options of a high-speed 4-wire UART and USB 2.0 full-speed (12 Mbps) are provided. Using advanced design techniques and process technology to reduce active and idle power, the CYW4339 is designed to address the needs of mobile devices that require minimal power consumption and compact size. It includes a power management unit which simplifies the system power topology and allows for direct operation from a mobile platform battery while maximizing battery life. The CYW4339 implements highly sophisticated enhanced collaborative coexistence ...
