Hardware DescriptionThe EK-LM3S9B92 evaluation kit contains two boards: the EK-LM3S9B92 evaluation board and the BD-ICDI JTAG debug board as described in more detail in this chapter.

Evaluation BoardThe EK-LM3S9B92 evaluation board uses the Stellaris® LM3S9B92 microcontroller and includes a 10/100 Ethernet port and a USB 2.0 full-speed OTG port. The board is intended for use with the ICDI board, but can be used as a standalone board as well. Figure 2-1 shows the block diagram.

Figure 2-1. EK-LM3S9B92 Evaluation Board Block Diagram

Functional DescriptionMicrocontroller, Reset, GPIO Pads, and JTAG (Schematic page 1)

MicrocontrollerThe evaluation board uses the Stellaris EK-LM3S9B92 microcontroller. A 16 MHz crystal provides the main oscillator clock which can directly drive the ARM core clock or can drive an internal PLL to increase the core clock up to 80 MHz. A 25 MHz crystal is used for the Ethernet clock.

The LM3S9B92 microcontroller has an internal LDO voltage regulator that supplies power for internal use. This rail requires only three capacitors for decoupling and is not connected to any other circuits.

Hardware Description

ResetA reset switch and R-C network connects to the microcontroller’s RSTn input. The reset signal is also connected to the JTAG/SWD connector J1 to allow reset control from the debugger.

GPIO PadsFour groups of oversized board pads with a 0.1” spacing provide access to GPIO signals and standard 0.1” pitch headers can be soldered to these pads. Pads are labeled with the corresponding GPIO signal, and pads with no labels are unconnected. Note that GPIO signals required for operation of the Ethernet port, USB port, and JTAG port are reserved for board use and are not available on these pads. Figure 2-2 shows the pad groups.

Figure 2-2. GPIO Pads

GPIO JumpersSome of the GPIO signals used by the board are connected to board jumpers and can be disconnected to provide additional user GPIOs. GPIOs PA0/PA1/PB4/PD0/PF2/PF3 are connected to jumpers JR1-JR6 respectively. Each signal can be freed by cutting the trace of the corresponding jumper (cut at white line on silkscreen). The jumper pads have the same footprint as an 0603 SMT resistor. To reconnect a previously cut jumper, solder a 0 ohm resistor to the corresponding jumper footprint.

JTAG/SWDThe JTAG/SWD connector J1 is used for program download and debug. This is a 2x5 fine pitch (0.050”) ARM JTAG connector, see (Figure 2-3) for signal definition. The LM3S9B92 microcontroller supports JTAG debug, Serial Wire Debug (SWD), and Serial Wire Out (SWO) trace with this connector. The ICDI board connects via a 10-wire ribbon cable to this connector.

PWR/UARTThe PWR/UART connector J2 is used to provide 5 V power from the ICDI board and also to connect the LM3S9B92 UART0 signals. This is a 2x4 fine pitch (0.050") connector, see (Figure 2-4) for signal definition. The UART0 signals are connected to GPIO jumpers JR1 and JR2 and can be disconnected from connector J2 if required, see “GPIO Jumpers” on page 14. The ICDI board connects via an 8-wire ribbon cable to this connector.

Figure 2-4. PWR/UART Connector

Ethernet, USB, Power and Miscellaneous (Schematic page 2)Page 2 of the schematics contains the Ethernet RJ45 connector, USB power switch and USB OTG connector, 3.3 V regulator, and power switch selector.

Ethernet PortThe on-board RJ45 connector provides a 10/100 base T Ethernet port. The RJ45 connector includes integrated LEDs and magnetics. The LEDs are connected to GPIO jumpers JR4 and JR5 and can be disconnected from the RJ45 connector if required, see GPIO Jumpers section.

USB PortThe on-board USB microAB connector provides a USB 2.0 full-speed port. To use as an On-The-Go (OTG) port, the power selector switch SW3 lever must be set to EXT. This selects an external 5 V power source to provide power to the board and the USB power switch. If the SW3 lever is set to USB, power to the board is received from USB, the on-board USB power switch output is disconnected from USB, and the board can only be used as a USB device. When using the USB-OTG port in Host mode, the current provided to a USB device should be limited to 100 mA or less when powered from the ICDI board. If powered from the 5 V test pad, then this can be increased to 500 mA.

Board PowerThe board requires 5 V for operation, and switch SW3 is used to select the power source. If the switch lever is moved towards the USB label on the board, power is received from the USB connector. If the switch lever is moved towards the EXTernal board label, the board is powered from the PWR/UART connector and the ICDI board provides power to this connector. DC regulator U2 generates 3.3 V for powering the board circuits and includes power indicator LED D1.

User DevicesPushbutton switch SW2 and LED D2 are available for the user and connected to PB4 and PD0 respectively. These GPIOs are connected to GPIO jumpers JR3 and JR4 and can be disconnected from SW2 and D2 if required, see GPIO Jumpers section.
