PRELIMINARY

WICED™ IEEE 802.11 a/b/g/n SoC with an

Embedded Applications Processor

The Cypress CYW43903 embedded wireless system-on-a-chip (SoC) is uniquely suited for Internet-of-Things applications. It sup-

ports all rates specified in the IEEE 802.11 b/g/n specifications.The device includes an ARM Cortex-based applications processor, a

single stream IEEE 802.11n MAC/baseband/radio, a power amplifier (PA), and a receive low-noise amplifier (LNA). It also supports

optional antenna diversity for improved RF performance in difficult environments.

The CYW43903 is an optimized SoC targeting embedded Internet-of-Things applications in the industrial and medical sensor, home

appliance markets. Using advanced design techniques and process technology to reduce active and idle power, the device is

designed for embedded applications that require minimal power consumption and a compact size.

The device includes a PMU for simplifying system power topology and allows for direct operation from a battery 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 1 provides

Cypress ordering part number that matches an existing IoT part number.

Features

■ On-chip power and low-noise amplifiers.

Application Processor Features

■ An internal fractional nPLL allows support for a wide range of

■ ARM Cortex-R4 32-bit RISC processor.

■ 1 MB of on-chip SRAM for code and data.

■ An on-chip cryptography core

reference clock frequencies.

■ Integrated ARM Cortex-R4 processor with tightly coupled

memory for complete WLAN subsystem functionality, mini-

mizing the need to wake up the applications processor for

standard WLAN functions (to further minimize power con-

sumption while maintaining the ability to upgrade to future

features in the field).

■ 640 KB of ROM containing WICED SDK components such

as RTOS and TCP/IP stack.

■ 17 GPIOs supported.

■ Q-SPI serial flash interface to support up to 40 Mbps of peak

■ Software architecture supported by standard WICED SDK

allows easy migration from existing discrete MCU designs

and to future devices.

transfer.

■ Support for UART (3), SPI or CSC master, interfaces.

(Cypress Serial Control (CSC) is an I²C-compatible inter-

face.)

■ Security support:

❐

WPA and WPA2 (Personal) support for powerful encryp-

tion and authentication.

Key IEEE 801.11x Features

AES and TKIP in hardware for faster data encryption and

IEEE 802.11i compatibility.

■ Single-band 2.4 GHz IEEE 802.11n compliant.

■ Single-stream spatial multiplexing up to 72 Mbps.

■ Supports 20 MHz channels with optional SGI.

Reference WLAN subsystem provides Cisco Compatible

Extensions (CCX, CCX 2.0, CCX 3.0, CCX 4.0, and CCX

5.0).

■ Full IEEE 802.11 b/g legacy compatibility with enhanced per-

formance.
