EM35x Breakout Board Technical Specification

Transcription

1 October B EM5x Breakout Board Technical Specification The Ember EM5x breakout board contains the hardware peripherals for the development and deployment of a low-data-rate, low-power ZigBee application on the EM00 series System-on-Chips (SoCs). The SoC is part of the four-layer (FR4-based) module that connects to the breakout board through the board-to-board connectors. The breakout board hardware stimuli include a temperature sensor, two buttons, a piezo buzzer, two LEDs, and a " x " through-hole prototyping area. In addition, the breakout board contains a USB transceiver with USB connector, a RS- transceiver with DB-9 connector, Data Emulation Interface (DEI), InSight Port (ISP) programming interface, and regulated power planes. You can obtain the breakout board voltage supply from one of four sources: InSight Adapter or ISA (via the InSight Port), external VDC supply, USB port, or AAA battery pack. The various voltage supplies offer a degree of flexibility when testing different network topologies. This document provides the technical specification for the EM5x breakout board. It describes the board-level interfaces as well as the key performance parameters. In addition, it provides the necessary information for developer to validate their application designs using the EM5x breakout board. Contents Breakout Board Features...

The first connection (Low Voltage) allows for a. to.5vdc external supply to be connected to J. (positive) and J (Ground). The power supply should be able to EM5x Breakout Board Technical Specification B

6 Page 6 source up to 50mA at the set voltage. When using a power supply in this mode, there should be no jumpers on J or J as shown in Table. The second connection (High Voltage) allows for a 4V to 0VDC external supply to be connected to J (positive) and J (Ground). The power supply should be able to source up to 00mA at the set voltage. When using a power supply in this mode, there should be a jumper connecting J. and J. as shown in Table. Battery connector (J8) The -pin, keyed battery connector (Hirose, P/N: DF-P-.5H(50)) allows for connection to a DC power supply or battery pack. The EM5x breakout board is shipped with a -AAA battery pack with appropriate mating connector for easy attachment. Batteries are sold separately. When using a battery pack, a jumper must be connected between J. and J. as shown in Table. InSight Port (J8) The EM5x breakout board can also be powered from an InSight Adapter (ISA). To enable this power supply, simply connect the ISA to the InSight Port (J8) and connect the power selection jumper between J and J. as shown in Table. In addition, the ISA selection toggle switch must be put in the INT position (as described in the InSight Adapter Technical Specification ( )). The ISA is able to source 50 ma of current at.0 V. Note: If the ISA is connected directly to the Insight Port on the Module, the jumper at J4 must be connected as well as the jumper across J and J.. USB Host (J5) The EM5x breakout board can also be powered by a USB Host (PC or Ember-supplied USB power supply). To operate in this mode, a USB Host must be connected to J5 and the power selection jumper must be connected between J. and J. as shown in Table. Module power supply To allow for accurate deep sleep current measurements, the EM5x breakout board isolates the module power supply from the regulated power domain on the breakout board. The only connection point between the module power supply and the breakout board supply is through the VMOD_EN header (J4). By isolating the module power supply in this manner, an ammeter can be placed across J4 to monitor the current sourced to the module. In addition an external power supply (. to.6vdc) can be connected to pin of J4 to supply power directly to the module. This connection scheme offers the highest degree of power supply flexibility. EM5x Breakout Board Technical Specification B

7 Page 7 ZigBee application peripherals As previously mentioned, the EM5x breakout board offers six peripherals to assist in ZigBee application development including: Temperature sensor Two () normally open buttons 4kHz piezo buzzer Two () LEDs Each peripheral connects to an EM5x GPIO through a two-pin peripheral header. Because each peripheral header on the EM5x breakout board ships with a jumper in place, the peripherals default to HW Enabled. If application development does not require the peripheral, simply remove the jumper. Note: Each peripheral consumes power. Be sure to factor this into the current consumption equations when testing the module in deep sleep mode or if using the battery pack to power the breakout board. Temperature sensor (U4) The temperature sensor is an off-the-shelf component from National Semiconductor (MFG P/N: LM0BIM7). The temperature sensor requires an enable signal to be asserted (active high) prior to generating an analog voltage proportional to the ambient temperature of the EM5x breakout board. Therefore, two EM5x GPIO signals, PC7 and PB5, are routed to pin of peripheral headers J and J5, respectively. PC7 enables the temperature sensor when asserted (active high), when a jumper is installed at J. PB5 contains the analog temperature information from the sensor, when it is enabled and a jumper is installed at J5. Due to the EM5x ADC voltage reference at.v, the temperature sensor output is scaled to between 0 and.v through a resistive voltage divider. If you want to connect a temperature sensor from a different manufacturer, scale the output in a similar manner. The EM5x breakout board is shipped with a jumper installed at J and J5. If the jumpers are removed, a different compatible device can be attached to pin of both J and J5. For more information on the temperature sensor, refer to its datasheet ( Buttons (EM, EM) Two programmable, normally-open buttons are provided for software debugging and application development. When either button is pressed, the connected net is driven low. A single-pole RC filter minimizes the effects of switching noise. EM5x Breakout Board Technical Specification B

8 Page 8 These buttons map to the backchannel button commands as follows: EM: controlled by the button 0 command EM: controlled by the button command For information about the button command, see the EM5x User Guide ( ). Two EM5x GPIO signals, PB6 and PC6, are routed from the EM5x Module to pin of peripheral headers J9 and J0, respectively. In the default configuration of the EM5x breakout board, jumpers are positioned across J9 and J0 to enable buttons EM and EM, respectively. If the jumpers are removed, different compatible devices can be attached to pin of breakout headers J9 and J0 instead of the buttons. Buzzer (SPK) A programmable buzzer is provided for software debugging and application development. An EM5x GPIO signal, PB7, is routed to pin of peripheral header J7. In the default configuration of the EM5x breakout board, a jumper is positioned across J7 to enable use of the buzzer. The buzzer installed on the EM50 breakout board is from CUI (MFG P/N: CEP-60). For more information on the buzzer, refer to its datasheet ( LEDs (DS6 and DS7) The EM5x breakout board contains two LEDs for software debugging and application development. Each LED is buffered (non-inverting) to allow for connection to any EM5x GPIO. One EM5x GPIO, PC5, is routed to pin of header J. To turn on DS7 (RED) from the EM5x RCM, install a jumper at J, configure PC5 as an output and drive it low. To turn on DS6 (GREEN), make a physical connection between an unused EM5x GPIO and J (single pin header). Once this is done, then that GPIO must be configured as an output and driven low to illuminate DS6. Serial communication for EM5x SC UART To enhance the software development experience, access to the EM5x SC UART is available directly from the EM5x breakout board or by telnetting into port 490 of an ISA connected to an Ethernet network. On the EM5x breakout board, it is available as RS-, USB and TTL-compliant signal levels. To minimize current consumption and allow for the different configuration options, the EM5x breakout board individually routes the EM5x SC UART signals TXD (EM5x PB), RXD (EM5x PB), nrts (EM5x PB), and ncts (EM5x PB4) to pin of headers J, J4, J5 and J6 respectively. To route the UART signals to the USB transceiver, connect the jumpers between pins and to each of the headers. Placing the jumpers across pins and route the UART signals to the RS- transceiver. To access the EM5x UART SC with an ISA, remove the jumpers on J, J4, J5 and J6 and place them on the InSight DEI jumper connector (J7) as summarized below and shown in Figure. RXD: J7. to J7. TXD: J7.5 to J7.6 ncts: J7.7 to J7.8 nrts: J7.9 to J7.0 Each jumper configuration is shown in Table. EM5x Breakout Board Technical Specification B

When connected to the InSight Adapter, the connector provides additional debug features to software developers. One feature involves the port 490 UART connection via ISA. To enable the UART connection to the EM50 UART signals, install four jumpers on J7 as shown in Figure. Another feature involves manipulation of BUTTON0 and BUTTON GPIO signals. To enable GPIO manipulation of BUTTON0 and BUTTON, install jumpers on J7 at PB6 and PC6, respectively. EM5x Module interface connector (J) Two single-row, 0.05 pitch, connectors make up the EM5x module interface to the EM5x breakout board. In addition, two single-row, guide connectors assist with connecting the EM5x module to the EM5x breakout board. The board-to-board connector scheme allows access to all EM5x GPIO as well as nreset and the JCLK signals. The connector is illustrated in Figure. EM5x Breakout Board Technical Specification B
