Hardware Description
Functional Description
This section describes the IDM-SBC’s hardware design in detail.
Microcontroller
The Stellaris LM39B92 is an ARM Cortex-M3-based microcontroller with 256-KB flash memory,
80-MHz operation, Ethernet, USB, EPI and a wide range of peripherals. See the LM39B92 data
sheet (order number DS-LM39B92) for complete device details.
The IDM-SBC’s LM39B92 microcontroller is factory programmed with a quickstart demo program.
The quickstart program resides in on-chip flash memory and runs each time power is applied,
unless the quickstart has been replaced with a user program.
Debugging
The microcontroller supports JTAG and SWD debugging as well as SWO trace capabilities. To
minimize board area, the IDM-SBC uses a 0.050” pitch header (J6) which matches ARM’s
fine-pitch definition (Figure 2-2). Some in-circuit debuggers provide a matching connector. Other
debuggers can be used with the MDL-ADA2 adaptor board included in the RDK.

Expansion Connector
UART0 signals from the microcontroller are available on J4, an internal expansion connector. The
pin-out of this connector is compatible with the power/UART cable used by the ICDI board
included in the EK-LM3S9B90 and EK-LM3S9B92 evaluation kits. This then provides a convenient
Virtual Com port interface to a PC. A pair of I2C signals are also available, however, jumpers
connecting SCL and SDA are normally omitted to avoid conflict with digital signals from the ICDI
board.

I2C is a short-distance intra-device bus that can be used to add capabilities such as an ADC (for
analog measurement) or digital inputs and outputs.
CAN is best suited for communication between devices. Refer to the CAN specification for
complete details on data rates and bus length.
Clocking
The IDM-SBC board uses a 16.0-MHz (Y2) crystal to complete the LM3S9B92 microcontroller's
main internal clock circuit. An internal PLL, configured in software, multiples this clock to higher
frequencies for core and peripheral timing.
A 25.0 MHz (Y1) crystal provides an accurate timebase for the Ethernet PHY.
Reset
The RESETn signal into the LM3S39B92 microcontroller connects to the JTAG/SWD debug
connector and to a simple R-C filter circuit to extend reset timing at power up.
The LCD Module has special Reset timing requirements requiring a dedicated control line from the
microcontroller.
SDRAM
The LM3S9B92 features an External Peripheral Interface (EPI) module, a high-speed 8/16/32-bit
parallel bus for connecting external peripherals or memory without glue logic. Supported modes
include SDRAM, SRAM and Flash memories, as well as Host-bus and FIFO modes.
On the IDM-SBC, the SDRAM device interfaces directly to the EPI and adds 8MB of memory (4M
x 16) which, once configured, becomes part of the LM3S9B92’s memory map at either
0x6000.0000 or 0x8000.0000.
The SDRAM interface multiplexes DQ00..14 and AD/BA0..14 without requiring external latches or
buffers. Of the 32 EPI signals, only 24 are used in SDRAM mode, with the remaining signals used
for non-EPI functions on the board.

Hardware Description
Power Supplies
The RDK-SBC has a wide input range switching-power supply that creates a 5V 1A rail for board
operation. The LM22672 step-down regulator switches at 500KHz with an efficiency of greater
than 90%. Board functions require only about 150 mA with the remaining capability available for
external interfaces such as USB host.
A low drop-out (LDO) regulator (U7) converts the +5V power rail to +3.3V to power digital devices
including the microcontroller and SDRAM.
USB
The LM3S9B92’s full-speed USB controller is configured for Host mode, allowing the SBC to
connect directly to USB Flash sticks and other USB devices.
U9, a fault-protected switch, controls and monitors power to the USB host port. USB_EPEN, the
control signal from the microcontroller, has a pull-down resistor to ensure host-port power remains
off during reset. The power switch will immediately cut power if the attached USB device draws
more than 1 Amp, or if the switches’ thermal limits are exceeded by a device drawing more than
500mA. USB_PFLT indicates the over-current status back to the microcontroller.
Ethernet
With its fully integrated 10/100 Ethernet MAC and PHY, the LM3S9B92 requires only a standard
Jack with integrated magnetics and a few passive components. The TX and RX signals are routed
to the jack as a differential pair. The PHY incorporates MDI/MDI-X cross-over, so the function of
the TX and RX pairs can be swapped in software.
The Ethernet jack incorporates two status LEDs that can be controlled directly by the Ethernet
PHY or by those same pins in GPIO mode.
Color QVGA LCD Touch Panel
The IDM-SBC features a TFT Liquid Crystal graphics panel with 320 x 240 pixel resolution. The
face of the panel is protected during shipping by a thin, protective plastic film which should be
removed before use.
The panel should be laid on a flat surface during evaluation, to protect it from damage and
maximize the sensitivity of the touch screen.
Features
Features of the LCD Panel include:
– Kitronix K350QVG-V1-F display
– 320 x RGB x 240 dots
– 3.5” 262K colors
– Wide temperature
– White LED backlight
– Integrated RAM
– Resistive touch panel

Control Interface
The Color LCD module has a built-in controller IC with a multi-mode parallel interface. The EVB
uses an 8-bit 8080 type interface with GPIO Port D providing the data bus.

Backlight
The white LED backlight must be powered for the display to be clearly visible. U9 (FAN5331B)
implements a 20mA constant-current LED power source to the backlight. The backlight is
controlled by the microcontroller using GPIO PJ7. The timer connected to this pin could be
configured to provide a modulated dimming signal
Because the FAN5331B operates in a constant current mode, its output voltage will jump up if the
LCD should become disconnected. To prevent over-voltage failure of the IC or diode D5, a zener
(D6) clamps the voltage. The current will limit to 20mA, but the total board current will be higher
than when the LCD panel is connected. If the LCD is not connected, avoid over-heating the
backlighting circuit, by setting PJ7 low to completely shut-down the circuit.
Power
The LCD module has internal bias voltage generators and requires only a single 3.3V dc supply.
Resistive Touch Panel
The 4-wire resistive touch panel interfaces directly to the microcontroller, using 2 ADC/GPIO
channels and 2 GPIO-only signals. The microcontroller creates a resistive divider by driving Y+
and Y- with 3.3V (VOH) and 0V (VOL) respectively. A voltage representing the Y-axis position is
then read on the X+ terminal. The process then repeats for the other axis. Note that when the
screen is not being touched, the X+ or Y+ sense inputs are floating. The software implements a
special state to discharge the capacitor (C10 or C15) to 0V and detect this condition.
Refer to the StellarisWare® source code for additional information on touch panel implementation.

Hardware Description
I2S Audio
The IDM-SBC has advanced audio capabilities using an I2S-connected Wolfson WM8510
CODEC. The CODEC’s integrated amplifier can directly drive an 8 Ω speaker. Although the
CODEC supports a microphone input, pin count limits on the LM3S9B92 result in this feature
being unconnected. The Microphone signals are still routed to connector J8 in-case the user
wishes to wire the ADCDAT signal to the LM3S9B92.

The Audio CODEC has a number of control registers which are configured using the I2C bus
signals. CODEC settings can only be written, but not read, using I2C. Refer to the StellarisWare®
example applications for programming information and to the WM8510 data sheet for complete
register details.
In the default configuration, the LM39B92 provides the master Bit Clock (BCLK) and System Clock
(MCLK) to the CODEC. Since the CODEC has only one set of clock I/Os for both audio-out and
audio-in functions, only the LM39B92 I2S module transmit clocks are connected.
DriverLib provides I2S source code, with most examples showing Audio Output.
Controller Area Network (CAN)
Controller Area Network (CAN) is a multicast, shared serial bus standard for connecting
automotive or industrial systems. The IDM-SBC board includes a CAN transceiver (U5) capable of
communicating at up to 1Mb/s. The end-points of the CAN bus should be properly terminated with
120? resistors.

Software Development
This chapter provides general information on software development as well as instructions for
Flash memory programming.
Software Description
The software provided with the IDM-SBC provides access to all of the peripheral devices supplied
in the design. The Stellaris Peripheral Driver Library is used to operate the on-chip peripherals, the
Stellaris Graphics Library is used to render graphical displays on the touch screen, and a set of
board-specific drivers are provided to access the off-chip functionality on the IDM-SBC.
The Stellaris Graphics Library provides two levels of support for rendering graphical elements. In
the lowest level, basic drawing primitives are provided, such as lines, circles, rectangles, and text
rendering. Each primitive supports clipping to a single clipping rectangle, allowing only a portion of
the display to be affected by the drawing primitives. Building upon the drawing primitives is a
widget set, which combines the drawing of graphical elements with reactions to pointer events (in
this case, presses on the touch screen). The widget set includes push buttons, check boxes, radio
buttons, sliders, listboxes, and drawing canvases. By using the widget set, complex interactive
graphical displays can be constructed quickly.
A set of drivers for the on-board peripherals is also provided. This includes a driver for the touch
screen, the audio codec, the USB, CAN, and the microSD card. Ethernet is supported by TCP/IP
stacks and example applications, all within the StellarisWare® libraries.
The IDM-SBC is also supplied with a set of example applications that utilize the Stellaris Peripheral
Driver Library and the Stellaris Graphics Library, along with the board-specific drivers for the
on-board peripherals. These applications demonstrate the capabilities of the IDM-SBC, and
provide a starting point for the development of the final application for use on the IDM-SBC. All
example applications are integrated with the Stellaris boot loader to allow automatic firmware
updates to be performed over the serial port using the LM Flash Programmer application.
Source Code
The complete source code for the IDM-SBC is included on the RDK-IDM-SBC CD. See the
Quickstart Guide for a detailed description of initial RDK hardware set up and how to install the
source code. The source code and binary files are installed in the DriverLib tree.
Tool Options
The source code installation includes directories containing projects and/or makefiles for the
following tool-chains:
November 28, 2011
•
Keil™ RealView® Microcontroller Development Kit (MDK-ARM)
•
IAR Embedded Workbench
•
Code Sourcery GCC development tools
•
Code Red Technologies development tools
•
Texas Instruments’ Code Composer Studio™ IDE

Software Development
Evaluation versions of these tools may be downloaded from www.ti.com/stellaris. Note that, due to
code size restrictions, the evaluation versions of the tools may not build all example programs for
the IDM. A full license is necessary to re-build or debug all examples.
Instructions on installing and using each of the evaluation tools can be found in the Quickstart
guides (for example, Quickstart-Keil, Quickstart-IAR) which are available for download from the
evaluation kit section of our web site at www.ti.com/stellaris.
For detailed information on using the tools, refer to the documentation included in the tool chain
installation or visit the website of the tools supplier.
Programming the IDM-SBC
The IDM-SBC software package includes pre-built binaries for each of the example applications. If
you installed DriverLib to the default installation path of C:\STELLARISWARE, you can find the
example applications for the IDM in “C:\STELLARISWARE\BOARDS\RDK-IDM-SBC”.
The Stellaris LM Flash Programmer is a free tool for programming Stellaris microcontrollers. It can
be used in two modes to update the firmware on the IDM-SBC. Most IDM-SBC example
applications are designed for use with the Stellaris boot loader which supports updating of the
main application firmware over Ethernet (this requires a board with Rev C or later of the LM39B92
microcontroller). Alternatively, the LM Flash Programmer utility can be used in conjunction with
any Stellaris evaluation board to program the IDM-SBC. The Stellaris evaluation board acts as a
USB-to-JTAG/SWD hardware interface and should be used in cases where the boot loader image
is not present or where the main application image is not behaving correctly and cannot transfer
control to the boot loader. However, in normal operation, it is more convenient to program via
Ethernet.
To program example applications into the IDM-SBC using the Ethernet-based firmware update
(this requires a board with Rev C or later of the LM39B92 microcontroller):
1. Install the LM Flash Programmer utility on a Windows PC.
2. Ensure that the IDM is connected to the same subnet of your Ethernet as the Windows PC
that will be used to program the device.
3. Apply power to the IDM.
4. Run LM Flash Programmer.
5. In the Configuration tab, select “Manual Configuration - see below” in the “Quick Set” list.
6. Select “Ethernet Interface” in the list below “Interface” and fill in the IP and MAC addresses for
the IDM you are trying to program. Each example application shows this information
somewhere on the IDM display. Note that it may take several seconds for the IP address to be
allocated.
7. If your PC has multiple network adapters, select the appropriate adapter in the “Ethernet
Adapter” list.
8. Move to the Program tab and click the Browse button. Navigate to the example applications
directory (the default location is “C:\STELLARISWARE\BOARDS\RDK-IDM-SBC””.
9. Each example application has its own directory. Navigate into the example directory that you
want to load and then go to the /gcc directory which contains the binary (*.bin) files. Select the
application binary file and click Open. Files that start with a “bl_” prefix are boot loader images
and cannot be updated using this method.
10. Click the Program button to start the download process.
11. The program starts once the download is complete.

November 28, 2011
Stellaris® IDM Single-Board Computer
To replace the boot loader image or to program example applications into the IDM-SBC using a
Stellaris evaluation board to provide JTAG/SWD functionality:
1. Install LM Flash Programmer on a Windows PC.
2. Connect the MDL-ADA2 10-pin to 20-pin adapter (included in the RDK) to the evaluation
board ribbon cable. This converts the standard 20-pin ARM header on the evaluation board to
a fine pitch ARM header.
3. Carefully connect the socket of the adaptor board to J1 on the IDM.
4. Apply power to the IDM and connect the evaluation board (available separately) to a USB port.
5. Run LM Flash Programmer.
6. In the Configuration Tab use the Quick Set control to select LM39B92.
7. Move to the Program Tab and click the Browse button. Navigate to the example applications
directory (the default location is “C:\STELLARISWARE\BOARDS\RDK-IDM-SBC).
8. Each example application has its own directory. Navigate into the example directory that you
wish to load and then into the /gcc directory which contains the binary (*.bin) files. Files named
with a “bl_” prefix are Stellaris boot loader images while those without the prefix are main
application images. Select the binary file and click Open.
9. Set the “Erase Method” to “Erase Necessary Pages” and check the “Verify After Program” box.
NOTE: Setting “Erase Entire Flash” when attempting to replace a main application image will
erase the boot loader image and result in a hang when the IDM next boots. If this occurs,
reflash a boot loader image using these instructions.
10. If flashing a boot loader image, set the “Program Address Offset:” value to 0x0000. If
programming a main application image, set this value to 0x1000.
11. Next, click on the Program button to start the Erase, Download, and Verify process.
12. Program execution will start once Verify is complete.
The Debuggers in each of the tool-chains also include Flash programming capabilities, including
support for high-performance in-circuit debug interfaces.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
