5.1. Push-Button Switches and LEDs (S1-2, DS5-6)
The UDP C8051F850 MCU Card has two push-button switches and two LEDs. The two LEDs connect to P1.0 and
P1.1, and the two switches connect to P1.7 and P2.1. The switches are normally open and pull the pin voltage to
ground when pressed. The LEDs connect to VDD through a current-limiting resistor and turn on when the
corresponding port pin is low.
The header J27 can be used to disconnect the switches and LEDs from the GPIO pins.

5.3. Potentiometer (R13)
The potentiometer is available on P1.2 (ADC0.10). To use the potentiometer, install a shorting block on J27 pins 9
and 10 to connect P1.2 to the potentiometer.
5.4. Voltage and Ground Reference (J32)
The C8051F850 has options to use an external voltage reference on the P0.0 / VREF pin and an external analog
ground reference on the P0.1 / AGND pin. The J32 header allows an external supply to clip to pin 1 for AGND and
pin 2 for VREF. These signals can then be connected to the MCU by populating a shorting block between pins 3
and 5 for AGND and pins 4 and 6 for VREF. Populating this shorting block for VREF connects P0.0 to the required
capacitors for the external reference.

5.5. VDD Power Select Switch (SW1)
The VDD power supply has two power options: UDP motherboard (PWR_VDD_OUT) and on-board +3.3 V
regulator power. The VDD Power Select switch is used to select between the two options. The +3.3 V regulator
power option is the upper +3.3_VREG position and allows the board to be powered from a diode-OR of four power
sources: 9 V Power Adapter (J6), the USB connector labeled COM PORT (J5), the USB Debug Adapter (J23), or
from the UDP motherboard bulk supply (PWR_5.0V_BULK).
5.6. Power LED (DS9)
The blue power LED provides visual feedback when the board is powered through USB, the 9 V power adapter, the
USB Debug Adapter, or from the UDP motherboard. The power LED indicates that power is available on the board
and the VDD Power Select switch must be configured properly to power the MCU.
5.7. Imeasure Jumper (JP2)
The Imeasure jumper (JP2) allows for easy access to measure the VDD current of the MCU. The shorting block for
this header is populated by default, and the direction of current is shown with a silk screen arrow. To measure the
supply current, remove the corresponding shorting block and connect a current measurement device across the
unpopulated header.
The voltage supply prior to the Imeasure jumper is the VDD pre-measure (VDD_PM) net, which supplies all of the
external LEDs, switches, USB COM, and reset pull-up. The VDD after the Imeasure jumper only connects to the
MCU.
5.8. Debug Header (J23)
The shrouded 10-pin debug header supports the Silicon Labs USB Debug Adapter. This connector provides a C2
debug connection to the C8051F85x/86x on the MCU card.
5.9. Reset Button (S5)
The reset push-button switch is just below the debug header (J23). Pushing this button will always reset the MCU.
Note that pushing this button while the IDE is connected to the MCU will result in the IDE disconnecting from the
target.
5.10. UART Connection Options (J7, U2, U4, U5)
The MCU card features a USB virtual COM port (VCP) UART connection via the mini-B USB connector (J5)
labeled COM PORT. The VCP connection uses the CP210x USB-to-UART bridge chip (U2). The GPIO pins
connected to the CP210x device can be enabled or disabled through the J7 header. Table 4 shows the GPIO pins
that are routed to the CP210x.
In addition to the CP210x USB-to-UART connection, the MCU card can connect the C8051F850 UART signals
with the UDP Motherboard UART signals UART_TX_SYS and UART_RX_SYS using U5. The signals to switch
between the two interfaces are UART_VCP_EN and UART_SYS_EN and are controlled by the motherboard. The
default selection with or without the motherboard is the CP210x VCP interface using a pull-down resistor R20.

5.11. Port Pin Headers (J24, J24, J26)
All of the MCU port pins are available on the 0.100-inch headers on MCU card. Each connector provides
connections to each port, VDD, and ground. Any unused pins on the P2 header are not connected. Some of these
port pins are shared with other functions on the board and may be modified as explained in Section 5.13.
Rev. 0.3

5.12. Electronic Board ID (EBID) (U1, J35)
The MCU card has a unique ID that can be read out from the Silicon Labs C8051F990 MCU (U1). This MCU
enables software tools to recognize the connected hardware and automatically select the appropriate firmware
image.
The EBID device uses two I2C signals to communicate: UDPBUS_SDA_A and UDPBUS_SCL_A. These signals
are connected to P0.6 and P0.7 on the C8051F850 MCU through the J25 header. These signals can be
disconnected from the MCU during power measurements.

5.13. MCU Port Pin Connections
The MCU card has many UDP connections for use with different I/O cards and the UDP motherboard. Table 6
describes all functions connected to each pin on the C8051F850 MCU. All of the UDP connections are made with
populated 0  ohm resistors on the back of the MCU card. To disconnect a signal from the pin, remove the 0 
resistor.

5. Move the VDD Select switch (SW2) to the lower MB position.
6. Connect the negative terminal of a bench power supply to board ground.
7. Connect the positive terminal of a bench power supply to the positive side (left pin) of the Imeasure
jumper. This will ensure that the /RST pin pull-up is powered.
Note: The pull-up resistor on /RST is powered by the VDD pre-measure (VDD_PM) net, which is separated from the VDD net
with the Imeasure shorting block (JP2) removed. Powering the MCU using VDD without powering the VDD_PM net will
prevent the IDE from communicating with the MCU.
8. Download the code to the board.
9. Remove the debug adapter connection.
10. Measure the power of the device.
