Debug and Release build configurations. The IDE can be used to manage multiple projects in a collection called a
workspace. Workspace settings are applied globally to all projects within the workspace. This can include settings
such as key bindings, window preferences, and code style and formatting options. Project actions, such as build
and debug are context sensitive. For example, the user must select a project in the Project Explorer view in order
to build that project.

The C8051F39x/F37x MCU cards enable application development on the C8051F390 or C8051F370 MCU. 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.

5.1. VDD Selection Switch (SW1)
The UDP C8051F390/F370 MCU Card has two power options. The VDD selector switch (SW1) selects the power
source for the C8051F39x/F37x VDD supply pin and the supply for the external peripheral circuits, VDD2.
The power sources for the on-board regulator (U1) are as follows:
9
es
ig
ns
The left VREG position selects the output of the on-board 3.3 V regulator (U5) for VDD and VDD2. This is the
primary supply option for development. The on-board regulator has multiple 5 V and 9 V power sources connected
via Schottky diodes to the regulator input. The highest voltage power source will supply power to the regulator.

receptacle (P2).
10-pin Debug connector (J2).
The UDP MB position on the VDD selector selects the UDP motherboard programmable supply (PWR_VDD_OUT)
as the power source. Use this position when using the programmable power supply under software control. The
UDP motherboard bulk 3.3 V supply (UDP_PWR_3.3V_BULK) supplies VDD2.
D
USB
N
ew
The VDD voltage is available on the J1 header. Ground is accessible at various test points on the MCU card, such
as header J3, J4, and J5. Use these test points to power the board from an external lab power supply. When using
a lab supply, the VDD selector switch should be in the UDP MB position with the MCU card disconnected from the
UDP motherboard.
The MCU card facilitates measurement of the MCU supply current by removing the R1 0 resistor and placing a
current meter in series with the two terminals of the J1 header.

r
5.2. Push-Button Switches and LEDs (SW3, D7)
The UDP C8051F390/F370 MCU Card has one push-button switch. Connect to switch to port pin P1.0 by placing a
shorting block on J8: SW - P1.0. The switch is normally open and pulls the pin voltage to ground when pressed.
m

de
d
Port pin P1.1 connects to one LED: D7 when a shorting block is placed on J8: LED - P1.1. The LEDs connect to
VDD2 through a current limiting resistor.
5.3. Debug Header (J2)
The standard 10-pin debug header supports the Silicon Labs USB Debug Adapter. This connector provides a C2
debug connection to C8051F39x/F37x. The USB Debug Adapter supports two types of debug connections: C2 and
JTAG. When using this MCU card with the Silicon Labs IDE, select C2 in the connection options dialog before
connecting.
om
The USB Debug Adapter also provides a 5 V power source that can power the regulator. When powering the MCU
from the debug connector, the SW1 switch must be in the VREG position. Additionally, select the Power Target
after Disconnect check box in the Silicon Labs IDE connections options dialog to ensure the MCU always has
power.
5.4. Reset Button (SW2)
N
ot
R
ec
The reset push-button switch is in the lower-right corner. 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.

C8051F39x/F37x
5.5. UART VCP Connection Options
The MCU card features a USB virtual COM port (VCP) UART connection via the USB connector (P2). The VCP
connection uses the CP2102 USB-to-UART bridge chip.
es
ig
ns
The UART pins on the target MCU either connect to the CP2102 USB-to-UART bridge chip or to the UDP
motherboard. The MCU card has level translators with enable pins that normally route the UART connections to
the on-board USB-to-UART bridge chip. However, the UDP motherboard can drive the enable pins to route the
UART connections to the UDP motherboard instead of the on-board USB-to-UART bridge chip. There are two
enable signals: one with a default pull-down (UART_VCP_EN) and one with a default pull-up (UART_SYS_EN).
When using the UART with either the on-board USB-to-UART bridge or the UDP motherboard, install shorting
blocks on header J14 to connect P0.4 to MCU_TX and P0.5 to MCU_RX.
D
If desired, install shorting blocks for hardware handshaking on P0.6 and P0.7 on the J14 header. Hardware
handshaking is not required for most applications. Firmware must implement hardware handshaking on the target
MCU using P0.6 and P0.7.
N
ew
5.6. Potentiometer (R36)
The potentiometer is available on P0.7 when a shorting block is placed on J13. To enable the potentiometer, place
a shorting block on J12 to connect the top terminal of the potentiometer to VDD2.
5.7. Screw Terminal (TB1)
fo
r
The MCU card includes a 5-position screw terminal connection capable of accepting large wires in the field. P0.6,
P0.1/IDAC0, P0.2/IDAC1, ground, and P0.0/VREF are available.
Before the VREF output can be observed on TB1, place a shorting block on J9 which connects P0.0/VREF to
4.7 µF and 0.1 µF decoupling capacitors.
m
en
de
d
Before the IDAC0 output can be observed on TB1 with an oscilliscope, place a shorting block on J10 which
connects P0.1/IDAC0 to a 1 k resistor to ground.
Before the IDAC1 output can be observed on TB1 with an oscilliscope, place a shorting block on J11 which
connects P1.2/IDAC1 to a 1 kresistor to ground.
5.8. Port Pin Headers (J3-J5)
All of the MCU port pins are available on the 0.100 inch headers.
N

om
Shorting blocks are placed on J6 and J7, connecting pins P0.2 and P0.3 to the P0.2 and P0.3 headers on J3. Pin
P0.2 and P0.3 can also connect to an external oscillator circuit. When using an external oscillator driver circuit,
remove the shorting block on J6 and J7.

5.9. C8051F39x Board Default and Optional Connections
es

ns
The C8051F39x MCU card has many default and optional connections for use with the UDP motherboard. The
default connections have shorting jumpers consisting of a 402 resistor footprint with solder connecting the two
pads. To disconnect a default connection, remove the solder between the pads. To reconnect, install a 0 402
resistor or connect the two pads with solder. The optional connections are non-populated (no-pop) resistor
footprints. To connect, install a 0 402 resistor or connect the two pads with solder.
Table 1 shows a summary of the default and optional connections for each pin. Further explanation of the UDP
motherboard signals can be found in Section 6.2.

6. Using the C8051F39x with the UDP Motherboard
6.1. VBAT Selector Switch
es
ig
ns
When used with the UDP motherboard, the motherboard can power the C8051F39x MCU card. With the VBAT
selector switch in the VREG position, the motherboard powers the regulator on the card. With the VBAT selector
switch in the UDP position, the UDP motherboard powers VBAT directly. This position supports software control of
the variable voltage power supply and current measurements.
The S1 switch on the UDP motherboard selects between the fixed or programmable voltage. The variable supply is
controlled by the C8051F384 board control MCU through the U1 digital potentiometer. Use the fixed supply when
the variable supply is not under software control.
6.2. MCU Card Header Connections
D
The C8051F39x 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 UDP C8051F390/F370 MCU Card card implements a subset of these connections.
The MCU card slot includes the following components:
N
ew
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
