PRELIMINARY
CYW43364
Features
IEEE 802.11x Key Features
■ Single-band 2.4 GHz IEEE 802.11b/g/n.
■ 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.
■ 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.
■ OneDriver™ software architecture for easy migration from
existing embedded WLAN.
■ Tx and Rx low-density parity check (LDPC) support for
improved range and power efficiency.
■ Supports standard SDIO v2.0 and gSPI host interfaces.
■ Supports space-time block coding (STBC) in the receiver.
General Features
■ Support diversity antenna.
■ 4 Kbitone-time programmable (OTP) memory for storing board
parameters.
■ Supports a battery voltage range from 3.0V to 4.8V with an
internal switching regulator.
■ Can be routed on low-cost 1-x-1 PCB stack-ups.
■ Programmable dynamic power management.
■ 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.
❐ Reference WLAN subsystem provides Wi-Fi protected setup
(WPS).
❐ AES in WLAN hardware for faster data encryption and IEEE
■ Worldwide regulatory support: Global products supported with
worldwide homologated design.
802.11i compatibility.
❐ Reference WLAN subsystem provides Cisco Compatible Ex-
tensions (CCX, CCX 2.0, CCX 3.0, CCX 4.0, CCX 5.0).
