pin-compatible with the existing Digi Connect Wi-ME 802.11b module allowing customers
to easily migrate to the next-generation version of the product.
The NS9210 processor provides a host of features such as an ARM926EJ-S core running at
speeds from 75-150MHz, on-chip AES encryption engine, one PICs, a serial port, SPI and
I2C interfaces, PWM, and others. Most importantly, it is a “drop-in” replacement for the
NS7520, which means that is the ideal upgrade vehicle to deliver a next-generation design.
The integrated FIM on the NS9210 processor offer interface flexibility allowing the
modules to provide high performance interface functionality and unique software-driven
configuration flexibility by dynamically loading software support for application specific
interfaces, e.g. UART, CAN, USB device, 1-Wire, SDIO, and others.
The Digi Connect Wi-ME 9210 embedded module offers freedom and flexibility of
professional embedded software development provided by the easy-to-use, cost-effective
and complete Digi JumpStart Kits™ for NET+OS and Microsoft.NET Micro Framework.
From medical systems to building control and industrial automation, in virtually any
application where embedded device connectivity over a wireless network is needed,
embedded modules are the ideal choice, delivering high-performance functionality.
Note:
Unless mentioned specifically by name, the products will be referred to as the
embedded modules or modules. Individual naming is used to differentiate product
specific features.
This chapter provides information about the modules hardware and contains the following
topics:

Types of Modules
There are two types of modules. One module utilizes Digi Plug-and-Play Firmware, while
the second is customizable with the option to develop a firmware application in .NET MF
or NET+OS. If you are developing your firmware application in NET+OS, you will be
using a module with a JTAG interface.
Note:
JTAG is a commonly used term that is also referred to as IEEE 1149.1, an industry
standard test protocol. JTAG is an abbreviation for the European Joint Test Action
Group, which invented the first versions of the IEEE 1149.1 interface. The JTAG
interface, along with the other development tools, enables you to download, run
and debug programs on the module.
The following figures show the two types of modules.
Note:
-S: No JTAG for use with Digi Plug-and-Play Firmware
-C: No JTAG for use with custom NET+OS applications
-JT: With JTAG for use with custom firmware development

Hard Reset
The embedded modules support a hardware reset on pin 8 of the 14-pin header. Pulling pin
8 low with an open drain driver will force the module into a hard reset state. The module
will remain in the reset state as long and pin 8 is held low and will leave this reset state
~250mS after pin 8 goes high. Do not actively drive pin 8 high and do not allow the rise
time of the pin 14 to be longer than 100uS. When used with the development board, this pin
is wired to reset button SW4, which means it acts as a hard reset button.
Connectors: Antenna
The Digi Connect Wi-ME is available with 1 RP-SMA connector. The antenna is
connected to the module with a reverse polarity SMA connector (sub-miniature size A).
The antenna only fits on the module one way to ensure a proper connection.

Reset
Hard Reset
The Wi-ME 9210 module supports a hardware reset via pin 8 of the 14-pin header. The unit
is forced into a hard reset when pulling the pin to ground, or less than 0.8v, for one
microsecond. When plugged into a development board, this pin is wired to the push button
at SW4. As a result, this switch acts as a hard reset button.

Flash
Depending on the variant, the Digi Connect Wi-ME 9210 has 8 or 16MB of flash memory.
The Digi Connect Wi-ME 9210/ARM9 family, the flash memory is controlled by chip
select 2 (default=st_cs1) and is located at 0x50000000.
SDRAM
The Digi Connect Wi-ME 9210’s SDRAM is controlled by chip select 1.
Depending on the variant, the module will have either 8 or 16MB of SDRAM memory.
The following table illustrates typical power consumptions using these power management
mechanisms. These measurements were taken with all Digi NS9210 processor’s I/O clocks
disabled except UART A, UART C, I/O Hub and Memory Clock0 using a standard module
plugged into a Digi JumpStart Kit development board, with nominal voltage applied:
Note 1: The current measurement was taken from the R6 current sense resistor using a 0.025 ohm shunt on the
JumpStart Kit development board. The supply voltage was 3.3V.
Note 2: This is the default power consumption mode when entering applicationStart(), as measured with the
napsave sample application. The value of the NS9210 Clock Configuration register (A090017C) is 0001200B
hexadecimal.
Note 3: This measurement was produced by selecting the “Clock Scale” menu option in the napsave sample
application.
Note 4: This measurement was produced by selecting the “Deep Sleep/Wakeup with an External IRA” menu
option in the napsave sample application.

Grounding Recommendation
It is recommended that you connect the tabs on the chassis of the Digi Connect ME / Wi-
ME, and the ground pins directly to the logic ground plane. It is also recommended that you
connect the Digi Connect ME / Wi-ME to the metal chassis of your enclosure. The idea is
to provide the shortest path or a path away from circuitry for ESD to travel to ground.

Power Management (Digi Connect ME 9210 only)
Using the Digi NET+OS development environment, applications on the Digi Connect Wi-
ME 9210 are capable of operating the module in several reduced power consumption
modes. These reduced power operating modes utilize the power management mechanisms
for the NS9210 processor for CPU clock scaling and sleep.
In the Clock Scaling mode, the system itself continues to execute instructions, but at a
different clock rate, which can be changed on-the-fly, using Digi’s patented circuitry inside
the NS9210 processor. The clock speed is changed programmatically to lower or raise the
system clock speed, thus reducing or increasing the module’s power footprint, respectively.
Additionally, a Sleep mode is available in which the system stops executing instructions.
Based on the application needs, wake-up triggers can be set up programmatically to
activate the processor back to wherever it left off. In this mode, a drastic power reduction is
realized by reducing the power consumption of the NS9210 processor and the on-module
PHY.
For sample power consumption figures for normal (typical) and power management related
operation of the Digi Connect Wi-ME 9210, see below:

Thermal Specifications
The table below shows the standard operating temperature ranges for the entire Digi
Connect ME family of embedded modules..
The lower standard operating temperature ranges are specified without restrictions, except
condensation must not occur.
The upper operating temperature limit depends on the host PCB layout and surrounding
environmental conditions. To simplify the customer’s design process, a maximum case
temperature has been specified.
The maximum case temperature must remain below the maximum, measured at the
location shown in the figure below.

Additional Design Recommendations
The following list provides additional design guidance with respect to thermal management
in applications with operating temperatures at the high end or beyond the specified standard
ambient temperature range.
Providing air movement will improve heat dissipation.
The host PCB plays a large part in dissipating the heat generated by the module.
A large copper plane located under the Digi Connect Wi-ME 9210 and soldered
to the module’s mounting tabs will improve the heat dissipation capabilities of
the PCB.
If the design allows, added buried PCB planes will also improve heat
dissipation. The copper planes create a larger surface to spread the heat into the
surrounding environment.
Adding a thermal pad or thermal compound, such as Sil-Pad®, Gap Pad® or
Gap Filler products made by the Bergquest Company
(www.bergquistcompany.com), between the host PCB and the underside of the
module will significantly increase the thermal transfer between the module’s
enclosure and the host PCB. Limit the fill area to the folded metal portion of the
module’s underside.
