  • Page 13: Chapter 2: Hardware Description

    C H A P T E R 2 Hardware Description The IDM-SBC design uses a Stellaris® LM39B92 microcontroller to handle display functions, touch-screen control, Ethernet, USB, CAN, and other peripheral functions. Only a few additional ICs are necessary to complete the design. The entire circuit is built on a compact four-layer printed circuit board.
  • Page 14: Functional Description

    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.
  • Page 15: Power And Interface Terminal Block

    Stellaris® IDM Single-Board Computer Power and Interface Terminal Block Power, CAN, and I C interfaces are provided through 3.5 mm pluggable terminal blocks. For convenience, the RDK includes the plugs. See the BOM for complete part numbers. Figure 2-4. Pluggable Terminal Blocks 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.
  • Page 16: Power Supplies

    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.
  • Page 17: Table 2-1. Lcd-Related Signals

    Stellaris® IDM Single-Board Computer 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. Table 2-1. LCD-Related Signals Microcontroller Pin Board Function PE6/ADC1...
  • Page 18: I 2 S Audio

    Hardware Description S 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.

    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.
