Introduction The Unified Development Platform (UDP) provides a development and demonstration platform for Silicon Laboratories microcontrollers, short-range wireless devices, and software tools, including the Silicon Laboratories Integrated Development Environment (IDE). Figure 1. Unified Development Platform Block Diagram Rev. 0.1 2/12 Copyright © 2012 by Silicon Laboratories SiM3U1xx UPIO-M3U1xx 2. Relevant Documents This document provides a hardware overview for the Unified Development Platform (UDP) system SiM3U1xx I/O card. Additional information on the UDP system can be found in the documents listed in this section. 2.1. Motherboard User’s Guide The UDP Motherboard User’s Guide contains information on the motherboard features and can be found at www.silabs.com/udp. 2.2. Card User’s Guides The UDP MCU, I/O, and radio test card User’s Guides can be found at www.silabs.com/udp. 2 Rev. 0.1 UPIO-M3U1xx 3. Hardware Setup Refer to Figure 2 for a diagram of the hardware configuration 1. Connect an MCU card to the UDP motherboard slot. 2. Connect the I/O card to the UDP motherboard slot. 3. (Optional) Connect a radio test card to the radio test card slot in the UDP motherboard. 4. (Optional) Connect an EZLink card to the EZLink card slot in the UDP motherboard. 5. Connect the USB Debug Adapter to the 2x5 debug connector on the MCU card with the 10-pin ribbon cable. 6. Connect one end of the USB cable to the USB connector on the USB Debug Adapter. 7. Connect the other end of the USB cable to a USB Port on the PC. 8. Connect the ac/dc power adapter to power jack J20 on the UDP motherboard. The board can also be powered from the J16 USB or J1 mini USB connectors. 9. Move the S3 power switch on the UDP motherboard to the ON position. Notes: Use the Reset button in the IDE to reset the target when connected using a USB Debug Adapter. Remove power from the target board and the USB Debug Adapter before connecting or disconnecting the ribbon cable from the target board. Connecting or disconnecting the cable when the devices have power can damage the device and/or the USB Debug Adapter. The MCU card can be used alone without the motherboard. However, the motherboard must be powered if an MCU card is connected. USB Debug Adapter USB Connector (J16) Power Adapter (J20) Figure 2.

UPIO-M3U1xx I/O Card Overview The SiM3U1xx I/O card expands the development hardware of the SiM3U1xx or SiM3C1xx devices. The card connects to the I/O Card expansion slot on the UDP motherboard and provides complete access to the MCU resources. Each expansion board has a unique ID that can be read out of an EEPROM or MCU on the board, which enables software tools to recognize the connected hardware and automatically select the appropriate firmware image. Figure 3 shows the SiM3U1xx I/O card. Figure 3.

UPIO-M3U1xx I/O Card Features 4.1. 7-Segment Displays The I/O card has two 7-segment displays driven by a Silicon Labs C8051F990 MCU. The C8051F990 is powered by the UDP motherboard and communicates to a UDP MCU card via I2C through the UDP connector. Debug connections to the C8051F990 are available via the J8 header. Table 2 shows the header connections. Table 1.

Switches and LEDs The I/O card has two push-button switches (SW2 and SW3) and six LEDs (DS1-5 and D1). The switches are normally open and pull the port pin voltage to ground when pressed. DS5 integrates a red, green and blue LED into a single component. D1 is a bright white LED. Table 2 shows the port pin connections. Table 2.

Joystick Switch The I/O card has five-position joystick switch (SW1). The joystick is normally open and pulls a port pin voltage to ground when the joystick placed in one of the five positions. Table 3 show the port pin connections to the joystick. Table 3. Joystick Switch Connections Joystick Position GPIO Pin Center Up Down Left Right PB3.3 PB2.13 PB3.0 PB2.14 PB3.1 4.4. Piezo Buzzer The I/O card has a piezo buzzer (LS1) connected to PB4.4 that resonates audibly when the voltage input is toggled periodically. 4.5. External Regulator Circuit The I/O card has a BJT transistor connected to four port pins to implement a regulator circuit with the SiM3U1xx EXTVREG module. The positive supply to the circuit can be 5 V from the UDP motherboard or PB3.8. PB3.9 connects to the negative supply and the collector of the BJT. The positive and negative supply are used to create a voltage drop across R42 to regulate the collector current. PB3.10 is connected to the output of the regulator circuit and the emitter of the BJT. PB3.11 is connected the base of the BJT and enables and disables the regulator circuit. 4.6. EBID MCU The I/O card has a unique ID that can be read out from the Silicon Labs C8051F990 MCU (U2). This MCU enables software tools to recognize the connected hardware and automatically select the appropriate firmware image. 6 Rev. 0.1 UPIO-M3U1xx 5. Using the I/O Card with the UDP Motherboard 5.1. Current Measurement The power measurement circuitry on the UDP motherboard consists of a Silicon Labs C8051F351 8051 MCU that measures both input voltage and current consumption of the MCU card, I/O expander, and radio test card. When using the I/O card, install a shorting block on the UDP Motherboard J15 and J13 connecting the two left pins together.

I/O Card Header Connections The I/O card has four connectors with 100 pins each. These 400 pins are directly tied to the UDP motherboard and MCU cards. These signals are named and designed to support a wide variety of features and applications, and the UPIO-M3U1xx card implements a subset of these connections. The MCU cards and I/O cards are designed so that a maximum number of functions are shared between each card. This allows a particular type of I/O card to be shared amongst all MCU cards that connect to the same signals. The I/O card slot includes the following components: J1 J2 J3 J4 The UPIO-M3U1xx card Appendix. MCU card connector H1 MCU card connector H2 MCU card connector H3 MCU card connector H4 implements the signals described in Table 5, Table 6, and Table 7, Table 8 in the Rev. 0.1 7 UPIO-M3U1xx 5.3. Shorting Blocks: Factory Defaults The UPIO-M3U1xx I/O Card has a factory pre-installed shorting block on J5. Figure 6 shows the position of the factory default shorting block. Figure 6.
