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 hardware mechanisms and algorithms, which
ensure that WLAN and Bluetooth collaboration is optimized for maximum performance. In addition, coexistence support for external
radios (such as LTE cellular, GPS, and WiMAX) is provided via an external interface. As a result, enhanced overall quality for
simultaneous voice, video, and data transmission is achieved.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Cypress 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.

PRELIMINARY
CYW4339
Features
IEEE 802.11x Key Features
IEEE 802.11ac compliant.
Single-stream spatial multiplexing up to 433.3 Mbps
data rate.
Supports 20, 40, and 80 MHz channels with optional
SGI (256 QAM modulation).
Full IEEE 802.11a/b/g/n legacy compatibility with
enhanced performance.
Tx and Rx low-density parity check (LDPC) support
for improved range and power efficiency.

Supports IEEE 802.11ac/n beamforming.
On-chip power amplifiers and low-noise amplifiers for
both bands.
Support for optional front-end modules (FEM) with
external PAs and LNAs
Shared Bluetooth and WLAN receive signal path elim-
inates the need for an external power splitter while
maintaining excellent sensitivity for both Bluetooth
and WLAN.
Internal fractional nPLL allows support for a wide
range of reference clock frequencies
Supports IEEE 802.15.2 external coexistence inter-
face to optimize bandwidth utilization with other co-
located wireless technologies such as LTE, GPS, or
WiMAX
Supports standard SDIO v3.0 (including DDR50 mode
at 50 MHz and SDR104 mode at 208 MHz, 4-bit and
1-bit) host interfaces.
