CYW43364
Single-Chip IEEE 802.11 b/g/n MAC/
Baseband/Radio
The Cypress CYW43364 is a highly integrated single-chip solution and offers the lowest RBOM in the industry for Internet of Things
(IoT) 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. 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 SDIO v2.0 mode, providing a raw data transfer rate up to 200 Mbps when operating in 4-bit mode
at a 50 MHz bus frequency.
Using advanced design techniques and process technology to reduce active and idle power, the CYW43364 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 while maximizing battery life.
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.

Features
IEEE 802.11x Key Features
Single-band 2.4 GHz IEEE 802.11b/g/n.
Support for 2.4 GHz Cypress TurboQAM® data rates (256-
QAM) and 20 MHz channel bandwidth.
Integrated iTR switch supports a single 2.4 GHz antenna.
Supports explicit IEEE 802.11n transmit beamforming.
Tx and Rx low-density parity check (LDPC) support for
improved range and power efficiency.
Supports standard SDIO v2.0 host interface.
Supports space-time block coding (STBC) in the receiver.
Integrated ARM Cortex-M3 processor and on-chip memory for
complete WLAN subsystem functionality, minimizing the need
to wake up the applications processor for standard WLAN
functions. This allows for further minimization of power
consumption, while maintaining the ability to field-upgrade with
future features. On-chip memory includes 512 KB SRAM and
640 KB ROM.
OneDriversoftware architecture for easy migration from
existing embedded WLAN.
General Features
Support diversity antenna.
Supports a battery voltage range from 3.0V to 4.8V with an
internal switching regulator.
Programmable dynamic power management.
4 Kbit one-time programmable (OTP) memory for storing board
parameters.
Can be routed on low-cost 1-x-1 PCB stack-ups.
74-ball WLBGA package (4.87 mm × 2.87 mm, 0.4 mm pitch).
Security:
WPA and WPA2 (Personal) support for powerful encryption
and authentication.
AES in WLAN hardware for faster data encryption and IEEE
802.11i compatibility.
Reference WLAN subsystem provides Cisco Compatible Ex-
tensions (CCX, CCX 2.0, CCX 3.0, CCX 4.0, CCX 5.0).
Reference WLAN subsystem provides Wi-Fi protected setup
(WPS).
Worldwide regulatory support: Global products supported with
worldwide homologated design.
