DESCRIPTION
The WB4343W and W43364 Wi-Fi®/Bluetooth®/Bluetooth Smart Mini
Modules are complete standalone solutions for designers looking to
take advantage of the high data rate of Wi-Fi, to interface to le gacy
Bluetooth Classic devices already in the field, and to utili ze the low
power consumption and mesh network capabilities of Bluetooth
Smart. They eliminate design risk and significantly reduce time-tomarket for a multitude of M2M applicat ions.
These devices are footprint-compatible with CEL’s existing line of
ZigBee
which easily transition between multiple wireless networking
standards via drop-in compatible module hardware.
The WB4343W and W43364 Mini Module family consists of four
drop-in compatible d evices so the feature set can be optimized for
your application. Options include Wi-Fi/Bluetooth/Bluetooth Smart
(WB4343W) or Wi-Fi only (W43364) radios, plus different MCU
memory sizes (STM32F411 MCU with 512kB flash/128kB RAM or
STM32F412 MCU with 1MB flash/256kB RAM).
Based on the Broadcom BCM4343W and BCM43364 transceivers and the ST Micro STM32 microprocessor, the
Cortet Mini Modules combine the BCM43xxx's 32-bit ARM
radio, LNA, PA, and internal transmit/receive RF switch with an ultra low power, high performance 32-bit ARM
Cortex
These devices leverage the world-class WICED™ SDK toolset from Broadcom, and are capable of running the
WICED stack plus the pro duct application code without requiring an additional m icroprocessor. The y are optimized
for small size and low power cons um ption, an d c an be run dir ectly from a rechargeable mobile platfor m battery. They
include Broadcom’s Enhanced Collaborative Coexistence algorithms and hardware mechanisms, allowing for an
extremely collaborative Wi-Fi and Bluetooth coexistence.

ANTENNA
The Cortet Mini Modules include an integrated Printed Circuit Board (PCB) trace antenna. An optional configuration which uses
a castellation pin on the module allows the user to connect to an external antenna. The WB43xxxSP2 family has been certified
with the PCB trace antenna only. The PCB antenna employs a topology that is compact and highly efficient. To maximize
range, an adequate ground plane must be provided on the host PCB. Correctly positioned, the ground plane on the host PCB
will contribute significantly to the antenna performance.
For optimum antenna performance, the Cortet Mini Module should be mounted with the PCB trace antenna overhanging the
edge of the host board. To further improve performance, a ground plane may be placed on the host board under the module, up
to the antenna but not extending under the antenna (a minimum of 1.5" x 1.5" is recommended). The installation of an
uninterrupted ground plane on a layer directly beneath the module will also allow traces to be routed under the layer. Refer to
the application note
The following are some design guidelines to help ensure optimal ante nna per for man ce:
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and
its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication.
Mini Modules Hardware Design Guidelines
The antenna portion of the Mini Module should hang over the host board so that there is not any additional
•
PCB under the antenna.
Never place the antenna close to metallic objects
•
In the final assembly, ensure that wiring and other components are not placed near the antenna
•
Do not place the antenna in a metallic or metalized plastic enclosure
•
Keep plastic enclosures a minimum of 1cm away from the antenna in any direction
•

PRELIMINARY DATASHEET
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et
d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope
rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante.
TRANSCEIVER IC
The WB43xxxSP2 family utilizes the BCM4343W or BCM43364 transceiver (WB4343WFxSP2 or W43364FxSP2 models
respectively), which is a highly integrated 2.4GHz WLAN IEEE 802.11 b/g/n MAC/baseband transceiver. It integrates a power
amplifier (PA) and a low-noise amplifier (LNA) for best-in-class receiver sensitivity and an internal transmit/receive RF switch.
The BCM4343W transceiver supports the Wi-Fi, Bluetooth, and Bluetooth Smart protocols, while the BCM43364 transceiver
supports Wi-Fi only.
Both transceivers also contain an ARM
software from the Link Control Layer up to the Host Controller Interface.

Cortex®-M3 32-bit RISC microprocessor, with 640kB ROM and 512kB RAM for running
MICROPROCESSOR
The Cortet Mini Modules contain a STM32 microprocessor from ST Micro, which is a 32-bit ARM® Cortex®-M4F processor
running at 100MHz. The WB43xxxF3 utilizes the STM32F411 with 512kB of flash and 128kB of SRAM, and the WB43xxxF4
utilizes the STM32F412 with 1MB of flash and 256kB of SRAM. Both MCUs support a rich set of peripherals, including SPI,
USART, I2C, 12-bit ADCs and timers. This ARM
single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory
protection unit (MPU) which enhances application security.
With the resources of the on-board STM32 microprocessor, the WB43xxxF3 and WB43xxxF4 Mini Modules are capable of
running the full Broadcom WICED stack plus the product application code, providing a full standalone solution. The WB43xxxF4
is ideal for resource-intensive applications like a Wi-Fi/Bluetooth Smart Bridge with support for Amazon Web Services and Apple
HomeKit, while the WB43xxxF3 is a more cost-effective solution for Wi-Fi enabled end devices.
®
Cortex®-M4F core features a floating point unit (FPU) which supports all ARM®
SOFTWARE/FIRMWARE
The Cortet Mini Modules utilize the WICED software development environment, which allows designers to quickly and easily
integrate Wi-Fi and Bluetooth connectivity into any product. WICED is an open-source build system based on GNU ‘make’ and
will also run on commercial toolchains such as IAR. It has a GUI development environment based on Eclipse CDT, and supports
a JTAG programmer and single-step, thread-aware debugger based on OpenOCD and gdb. The WICED platform offers several
RTOS/TCP stack options, has a simple API for accessing hardware peripherals, and includes advanced security and networking
features like SSL/TLS and IPv4/IPv6 TCP/IP networking stacks. It is a production-ready application framework, including a
bootloader, flash storage API, over-the-air upgrades, factory reset, and a system monitor.
