CYW4354
Single-Chip 5G Wi-Fi IEEE 802.11ac 2×2 MAC/Baseband/Radio
with Integrated Bluetooth 4.1 and FM Receiver
The Cypress CYW4354 is a complete dual–band (2.4 GHz and 5 GHz) 5G Wi–Fi 2 × 2 MIMO® MAC/PHY/Radio System–on–a–Chip.
This Wi–Fi single–chip device provides a high level of integration with dual–stream IEEE 802.11ac MAC/baseband/radio, Bluetooth
4.1, and FM radio receiver. 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 867 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 power amplifiers and receive low noise amplifiers.
For the WLAN section, several alternative host interface options are included: an SDIO v3.0 interface that can operate in 4b or 1b
modes, a high-speed inter-chip (HSIC) interface, and a PCIe v3.0 compliant interface running at Gen1 speeds. For the Bluetooth
section, host interface options of a high-speed 4-wire UART and USB 2.0 full-speed (12 Mbps) are provided.
The CYW4354 uses advanced design techniques and process technology to reduce active and idle power, and includes an embedded
power management unit that simplifies the system power topology.
In addition, the CYW4354 implements highly sophisticated enhanced collaborative coexistence hardware mechanisms and algorithms
that ensure that WLAN and Bluetooth collaboration is optimized for maximum performance. Coexistence support for external radios
(such as LTE cellular and GPS) is provided via an external interface. As a result, enhanced overall quality for simultaneous voice,
video, and data transmission on a handheld system is achieved.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion,
there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides
Cypress ordering part number that matches an existing IoT part number.
