Baseband/ Radio with Integrated Bluetooth 5.0
The Cypress CYW43455 single-chip device provides the highest level of integration for Internet of Things applications and handheld
wireless system with integrated single-stream IEEE 802.11ac MAC/baseband/radio and, Bluetooth 5.0.
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 of up to 433.3 Mbps. All rates specified in the 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 and LNAs are also supported.
The WLAN section supports the following host interface options: an SDIO v3.0 interface that can operate in 4b or 1b mode, a
high-speed 4-wire UART, and a PCIe1Gen1 (3.0 compliant) interface. The Bluetooth section supports a high-speed 4-wire UART
interface.
Using advanced design techniques and process technology to reduce active and idle power, the CYW43455 is designed to address
the needs of mobile devices that require minimal power consumption and compact size. It includes a power management unit which
