1 GENERAL DESCRIPTION
The Inventek ISM43362-M3X-L44 is an embedded (eS-WiFiTM) wireless Internet
Connectivity device. The Wi-Fi module hardware consists of an STM M3 Cortex host
processor, integrated antenna (or optional ext. antenna) and Broadcom Wi-Fi device all
interconnected. The module provides UART, USB and SPI interfaces enabling
connection to an embedded design. The Wi-Fi module requires no operating system
and has a completely integrated TCP/IP Stack that only requires AT commands to
establish connectivity for your wireless product, minimizing development time, testing
routines and certification. The low cost, small foot print (14.5 mm x 30 mm) and ease of
design-in make it ideal for a range of embedded applications. The module hardware can
be used with Inventek’s AT Command set or the Broadcom’s WICEDTM SDK.
Summary of Key Features:
802.11 b/g/ n compliant based on Broadcom MAC/Baseband/Radio device.

Stop Mode is initiated by software and exited by the Wakeup pin. (Wakeup pin is 3.3 volt
tolerant). The wakeup pin is an external interrupt pin that on the rising edge will cause the
module to exit stop mode. It is an edge trigged input. It is critical to have no glitch on this line.

8.2.1 SPI Communication Overview:
With the exception of initial cursor, all communication with the module happens synchronously.
In other words, the SPI Master must always poll for every asynchronous event.
A typical command flow is provided flow. This is an example using the Direct Connect Soft AP
with a TCP communication server.
SPI Master
SPI Slave
Description
“\r\n> “
Prompt
“AS=0,ABC\r\x15”
"\r\n\r\nOK\r\n> "
Set Access Point SSID
“AD\r\x15”
"\r\n\r\nOK\r\n> "
Start AP - Direct Mode
"P1=0\r\x15"
"\r\n\r\nOK\r\n> "
Set TCP Protocol
"P4=2000\r"
"\r\n\r\nOK\r\n> "
Set TCP Port
"P5=1\r\x15"
"\r\n\r\nOK\r\n> "
Start TCP COMM Server
"MR\r\x15"
"\r\n[SOMA]...[EOMA]\r\nOK\r\n> Read Messages
Note: [SOMA] - Start Of Message Asynchronous, [EOMA] - End Of Message Asynchronous
The SPI communication is always 16-bit and can be sustained up to 20MHz. The eS-WiFi
module after power up or reset will raise CMD/DATA READY pin to signal that the first Data
Phase has started. In this mode, the SPI Host must fetch the cursor. As provided by the example
above, this is the only time host needs fetch data from slave without issuing a command.
The Host will initiate a SPI cycle (lower SSN) and clock out 0x0A (Line Feed) until the
CMD/DATA READY pin lowers signaling the end of the Data Phase. The data received will be
0x0d (CR) 0x0A (LF) 0x3E (>) 0x20 (SP).
The next rising edge of the CMD/DATA READY pin signals the Command Phase.
8.2.2 SPI Command Phase:
The Command Phase indicates the eS-WiFi module is ready to accept a AT Command. The
command must include all delimiters and data for the command.
Ex.
S3=0010\r0123456789
The command must also be sent as one continuous SPI cycle, that is SSN must stay low for the
complete command, delimiters, and data.
The Host will initiate a SPI cycle (lower SSN) and clock out the command, delimiters and
associated data and raise the NSS signal to indicated that the all data has be sent. As result of the
NNS raising the eS-WiFi module will lower the CMD/DATA READY pin to signal the end
Command Phase.
The data that will be clocked back to the Host will be 0x15 (NAK).

ISM43362-M3X Product Specification
8.2.3 SPI Data Phase:
The Data Phase indicates the eS-WiFi module has data ready for the Host to read. The eS-WiFi
module will raise CMD/DATA READY and the Host will initiate a SPI cycle (lower SSN) and
clock out 0x0A (Line Feed) until the CMD/DATA READY pin lowers signaling the end of the
Data Phase.
8.2.4 SPI Asynchronous Messages:
There are certain situations in which the eS-WiFi will issue asynchronous messages:
Soft AP (AO/AD Commands), when a device connects to the Soft AP a DHCP assigned
message will issued.
Ex. [DHCP ] Assigned 00:00:00:00:00:00 has 192.168.10.100
TCP/UDP Communication Servers (P5=1), when a client connects to the server a
connected message will be issued.
Ex. [TCP SVR] Waiting on connection...
[TCP SVR] Accepted 192.168.10.100:2000
[UDP SVR] Accepted 192.168.10.100:2000
With the SPI host interface being synchronous the Host must poll for these messages. This can
be done by using the MR (Message Read) command or when a Communication connection the
issuing of a R0 command will read all asynchronous message and the result of the R0 command.
The asynchronous messages are delineated by the Start Of Message Asynchronous ([SOMA])
and End Of Message Asynchronous ([EOMA]) markers.

14 Product Compliance Considerations
RoHS: Restriction of Hazardous Substances (RoHS) directive has come into force since
1st July 2006 all electronic products sold in the EU must be free of hazardous materials,
such as lead. Inventek is fully committed to being one of the first to introduce lead-free
GPS products while maintaining backwards compatibility and focusing on a
continuously high level of product and manufacturing quality.
EMI/EMC: The Inventek module design embeds EMI/EMC suppression features and
accommodations to allow for higher operational reliability in noisier (RF) environments
and easier integration compliance in host (OEM) applications.
FCC/CE: The module will be in compliance test for FCC/CE
15 Reflow Profile

16.2 Device baking requirements prior to assembly
Boards must be baked prior to rework or assembly to avoid damaging moisture sensitive
components during localized reflow. The default bake cycles is 24 hours at 125C.
Maintaining proper control of moisture uptake in components is critical.
Before opening the shipping bag and attempting solder reflow, you should maintain a
minimal out-of-bag time and ensure the highest possible package reliability for the final
product.
Module’s Assembly Instructions
Board Placement: The ISM43362-M3G-L44 has an optional on board Wi-Fi antenna.
The board is designed to be a stuffing option. If you elect to use the on board antenna,
then board placement is critical in your system. Several key things to consider when
placing the module are:
Ensure that the antenna portion of the design is placed so that the antenna has
no ground plane under, above or near the antenna. Ideally, the antenna requires
clear sky for optimal performance. If you have shields or other material around
the antenna, please test for interference and loss of signal strength.
