C8051F85x/86x MCU Card Overview The C8051F850 MCU card enables application development on the C8051F85x/86x MCU device family. The card connects to the MCU 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. The target MCU card can also be detached from the UDP and used alone as a development or demonstration tool. Figure 6 and Figure 7 highlight the C8051F850 MCU card features.

C8051F850 MCU Card Features—Back Rev. 0.2 9 C8051F850-DK-UG 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. Table 1. Switch and LED Pin Descriptions MCU Pin Function PB1.0 PB1.1 PB1.7 PB2.1 Red LED DS5 (LED1) Red LED DS6 (LED2) Switch S1 Switch S2 5.2. Analog Terminals (J34) Several of the C8051F850 port pins used for analog functions are connected to the J34 terminal block. Refer to Table 2 for the J34 terminal block connections. Table 2. Terminal Block Pin Descriptions (J34) Terminal Pin MCU I/O 1 2 3 4 5 6 VREF / P0.0 GND ADC0.9 / P1.1 ADC0.12 / P1.4 ADC0.10 / P1.2 ADC0.13 / P1.5 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. Table 3. Terminal Block Pin Descriptions (J25) 10 MCU Pin Analog Signal Description P0.0 VREF P0.1 AGND Clip external source to J32 pin 2, apply shorting block between pins 4 and 6 to connect to the MCU Clip external ground to J32 pin 1, apply shorting block between pins 3 and 5 to connect to the MCU Rev. 0.2 C8051F850-DK-UG 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. Table 4. CP210x Controlled GPIO Pins MCU Pin COM Function P0.4 P0.5 VDD UART Transmit UART Receive COM VIO 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. 0.2 11 C8051F850-DK-UG 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. Table 5. Terminal Block Pin Descriptions (J25) MCU Pin EBID / UDP Signal P0.6 P0.7 UDPBUS_SDA_A UDPBUS_SCL_A 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. Table 6.

Using the C8051F850 MCU Card with the UDP Motherboard 6.1. 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. Install a shorting block on the UDP Motherboard J13 and J15 and connect the two left pins together when using the motherboard with the C8051F850 MCU card.

Power Measurement Diagram with Shorting Blocks 6.2. MCU Card Header Connections The MCU card has four connectors with 100 pins each. These 400 pins are directly tied to the UDP motherboard and I/O cards. These signals are named and designed to support a wide variety of features and applications, and the C8051F850 MCU 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 MCU card slot includes the following components: J1 MCU card connector H1 J2 MCU card connector H2 J3 MCU card connector H3 J4 MCU card connector H4 The C8051F850 MCU card implements the signals described in Table 8, Table 9, Table 10, and Table 11 in the Appendix. Rev. 0.2 13 C8051F850-DK-UG 7. Shorting Blocks: Factory Defaults The C8051F850 MCU card comes from the factory with pre-installed shorting blocks on several headers. Figure 9 shows the positions of the factory default shorting blocks. Figure 9. Shorting Blocks: Factory Defaults A shorting block is installed across the JP2 Imeasure header to enable power to the MCU. Shorting blocks are installed on J7 to enable the virtual COM port. Shorting blocks are also installed on J27 to enable the switches, LEDs, and potentiometer to be connected to GPIO pins. 14 Rev. 0.2 C8051F850-DK-UG 8. Power Measurement The C8051F850 MCU card includes a JP2 Imeasure jumper for MCU power measurement purposes. The VDD supply on pin 2 of the header connects only to the MCU on the board. The VDD pre-measure (VDD_PM) supply on pin 1 of the JP2 header powers the external LEDs, switches, reset switch, potentiometer, and VCP COM. 8.1. Measuring Power with Fixed VDD To measure the power of the C8051F850 MCU using the MCU card at a fixed 3.3 V: 1. Connect a USB Debug Adapter to the 10-pin shrouded debug connector (J23). 2. Remove the three shorting blocks from J7. 3. Remove the JP2 Imeasure shorting block. 4. Connect a multimeter across (positive side on the left pin, current flow indicated by the silk screen arrow). 5. Move the VDD Select switch (SW2) to the upper +3.3V_VREG position. 6. Connect the 9 V power adapter to POWER (J6). 7. Download the code to the board. 8. Remove the debug adapter connection. 9. Measure the power of the device. 2 6 USB Debug Adapter 1 4 8 +000.500 3 µADC 5 Figure 10. C8051F850 MCU Card Power Measurement Configuration— Fixed VDD Rev. 0.2 15 C8051F850-DK-UG 8.2. Measuring Power with Varying VDD To measure power with a varying VDD: 1. Connect a USB Debug Adapter to the 10-pin shrouded debug connector (J23). 2. Remove the three shorting blocks from J7. 3. Remove the JP2 Imeasure shorting block. 4. Connect a multimeter across the JP2 Imeasure jumper (positive side on the left pin, current flow indicated by the silk screen arrow). 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. 2 USB Debug Adapter 1 4 +000.500 µADC 2.8 V 9 3 6 5 7 Figure 11. C8051F850 MCU Card Power Measurement Configuration—Varying VDD 9.
