ISM43340-M4G-L44 Product Specification
1 GENERAL DESCRIPTION
The Inventek ISM43340-M4G-L44 is an embedded Serial WiFi (eS-WiFi), wireless
internet connectivity module that operates in the 2.4 & 5.0 GHz spectrum. The
eS-WiFi
module’s hardware consists of an ARM Cortex M4 host processor, Cypress CYW43340
Dual-Band (2.4 GHz / 5 GHz) 802.11 a/b/g/n MAC/Baseband/Radio with Integrated
Bluetooth 4.0. The ISM43340
eS-WiFi
module is compatible with the Bluetooth Low
Energy operating mode, which provides a dramatic reduction in the power consumption
of the Bluetooth radio and baseband. The primary application for this mode is to
provide support for low data rate devices, such as sensors and remote controls. An
independent, high-speed UART is provided for the Bluetooth host interface
The
eS-WiFi
module has two antenna options, an on board dual band chip 2.4 & 5 GHz
or a U.FL external 2.4 & 5 GHz antenna. The ISM43340
eS-WiFi
module includes
integrated power amplifiers, LNAs and T/R switches for the 2.4 GHz and 5 GHz WLAN
bands, greatly reducing the external part count, PCB footprint, and cost of the solution.
The
eS-WiFi
module provides UART and SPI interfaces enabling connection to an
embedded design. The
eS-WiFi
module requires no operating system and has a
completely integrated TCP/IP Stack. The
eS-WiFi
module hardware can be used with
Inventek’s
IWIN
(Inventek Wireless Interoperability Network), AT Command set or with
Cypress’ WICED
TM
SDK3.1.2 or later.
Inventek’s
IWIN,
AT command set, allows you to quickly establish connectivity for your
wireless product, minimizing development time, testing routines and certification. The
low cost, small foot print (14.5 mm x 34 mm) and ease of design-in make it ideal for a
range of embedded applications.
Hardware Features:
Uses CYW43340 Cypress Leading Edge Radio Device.
Includes STM32F405 ST Cortex M4 Microcontroller.
2.4 GHz and 5.0 GHz Bands.
Bluetooth 4.0 including BLE Support.
2.4 & 5 GHz Chip Antenna on the
eS-WiFi
module (FCC/CE/IE certified).
U.FL Connector for external 2.4 GHz & 5GHz Antenna (FCC/CE/IE certified).
Configurable using Inventek’s proprietary
IWIN
AT commands.
Host interface: UART, SPI.
44-Pin and L44+10 Land Grid Array Footprint (7 GPIO for
IWIN
& 17 GPIO for WICED).
14.7mm x 34mm x 2.5 mm
5 GPIO’s for SPI or ADC (SPI uses ADC Pins)
Input Voltage: 3.3 V
Low power operation with built-in low power modes.
Proven Interoperability … Connects with other a/b/g/n Access Points in the Wireless LAN.
