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.

4. 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 4. 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.

4.2. 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.

4.3. 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.

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.

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.

5.2. 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:
