 7About the Digi Connect Wi-ME Embedded ModuleCHAPTER 1OverviewThe Digi Connect Wi-ME 9210 b/g is a fully customizable and secure 802.11b/g wireless embedded module that provides integration flexibility in a variety of connection options. Built on the new Digi NS9210 processor in combination with a 802.11bgn Wi-Fi radio, it is 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" on page 8"Connectors: Antenna" on page 11"JTAG Jumper" on page 10"Module LEDs" on page 12

8 Types of ModulesThere 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 developmentDigi Connect Wi-ME ModulesModel Description FigureDC-WME-Y402-JT Used for development purposes onlyJTAG interfaceDC-WME-Y402-SDC-WME-Y402-CNo JTAG interfaceOrdered independently for use in your implementation.

 11Hard ResetThe 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: AntennaThe 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.

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.SDRAMThe 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.Mode Power Consumption1Normal Tx Operational Mode 1.7W (520mA peak)Normal Receive Operational Mode21.14W (346mA)Full Clock Scaling Mode3.613W (186mA)Sleep Mode4.469/w (146mA)

 37Grounding RecommendationIt 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.InputsSymbol Description Min Typ Max UnitVIH Input High Voltage 2 — VCC+0.3a a.)

38 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:3.3VDC @ 346 mA typical (1.14W)UART and Rx activatedSleep Mode (approximate)3.3VDC @ 142mA

 39Thermal SpecificationsThe 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.

40 Additional Design RecommendationsThe 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.MechanicalDimensions Digi ConnectWi-MELength 1.445 in.(36.703 mm)Width 0.75 in. (19.05 mm)Height 0.854 in.
