4.5. Silicon Labs Battery Life Estimator
The Battery Life Estimator is a system design tool for battery-operated devices. It allows the user to select the type
of battery they are using in the system and enter the supply current profile of their application. Using this
information, it performs a simulation and provides an estimated system operating time. The Battery Life Estimator
is shown in Figure 6.
Figure 6. Battery Life Estimator Utility
From Figure 6, the two inputs to the Battery Life Estimator are battery type and discharge profile. The utility
includes battery profiles for common battery types such as AAA, AA, A76 Button Cell, and CR2032 coin cell. The
discharge profile is application-specific and describes the supply current requirements of the system under various
supply voltages and battery configurations. The discharge profile is independent of the selected power source.
Several read-only discharge profiles for common applications are included in the pulldown menu. The user may
also create a new profile for their own applications.
To create a new profile:
1. Select the profile that most closely matches the target application or choose the "Custom Profile".
2. Click Manage.
3. Click Duplicate.
4. Click Edit.
Profiles may be edited with the easy-to-use GUI (shown in Figure 7).
Rev. 0.2

C8051F96x/Si102x
Figure 7. Battery Life Estimator Discharge Profile Editor
The Discharge Profile Editor allows the user to modify the profile name and description. The four text entry boxes
on the left hand side of the form allow the user to specify the amount of time the system spends in each power
mode. On the right hand side, the user may specify the supply current of the system in each power mode.
Since supply current is typically dependent on supply voltage, the discharge profile editor provides two columns for
supply current. The V2 and V1 voltages at the top of the two columns specify the voltages at which the current
measurements were taken. The Battery Life Estimator creates a linear approximation based on the input data and
is able to feed the simulation engine with an approximate supply current demand for every input voltage.
The minimum system operating voltage input field allows the system operating time to stop increasing when the
simulated battery voltage drops below a certain threshold. This is primarily to allow operating time estimates for
systems that cannot operate down to 1.8 V, which is the voltage of two fully drained single-cell batteries placed in
series.

C8051F96x/Si102x
The wakeup frequency box calculates the period of a single iteration through the four power modes and displays
the system wake up frequency. This is typically the "sample rate" in low power analog sensors.
Once the battery type and discharge profile is specified, the user can click the "Simulate" button to start a new
simulation. The simulation engine calculates the estimated battery life when using one single-cell battery, two
single-cell batteries in series, and two single-cell batteries in parallel. Figure 8 shows the simulation output window.
Figure 8. Battery Life Estimator Utility Simulation Results Form
The primary outputs of the Battery Life Estimator are an estimated system operating time and a simulated graph of
battery voltage vs. time. Additional outputs include estimated battery capacity, average current, self-discharge
current, and the ability to export graph data to a comma delimited text file for plotting in an external graphing
application.

5. UDP C8051F960/Si1020 MCU Card with Multiplexed LCD MCU Card
Overview
The C8051F96x MCU card enables application development on the C8051F960 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.
Figure 9 shows the C8051F96x MCU card.

5.1. UPPI Pico Board Connector (J5, J6, J7, J8)
The UPPI Pico Board connector accommodates a variety of C8051F96x and Si102x/3x UPPI Pico Boards. The
C8051F960 MCU and Si1020 Wireless MCU UPPI Pico Boards share a common form factor. This enables the
MCU card to support a wide variety of wired and wireless applications.
The supported UPPI Pico Boards include:
UPPI-F960
UPPI-Si1020GMxxxTR
The Si1020/30 UPPI Pico Boards include an EZRadioPRO® transceiver. The C8051F960 UPPI Pico Boards do not
include an RF transceiver; instead, these boards support most Silicon Labs 40-pin radio test cards when used with
the Unified Development Platform Motherboard.
Rev. 0.2

C8051F96x/Si102x
5.2. Multiplexed LCD Display (DS1)
The C8051F960 MCU Card with Multiplexed LCD includes a 4-mux, 128-segment alphanumeric LCD. The LCD
has eight 14-segment characters and includes decimal points and apostrophes. The large display is easy to read
from a distance.
The LCD display uses all of the C8051F960/Si1020 common and segment LCD pins, leaving 21 pins available on
the C8051F960 for other purposes. For applications that do not require an LCD and need additional I/O, the UDP
C8051F960 MCU card with EMIF (UPMP-F960-EMIF) has 57 available I/O pins when used with the C8051F960
UPPI Pico Board.
The provided example code makes using the alphanumeric display by calling a custom ANSI C printf function.
5.3. Push-Button Switches and LEDs (SW1-SW4, LED1-LED4)
The UDP C8051F960/Si1020 MCU Card with Multiplexed LCD has four push-button switches. The four switches
connect to P0.0 through P0.3. The switches are normally open and pull the pin voltage to ground when pressed.
When using P0.3 for SW4, install a shorting block on J16 connecting P0.3 to SW4/LED4.
Port pins P0.0 through P0.3 also connect to four LEDs: LED1 through LED4. The LEDs connect to VIO through a
current limiting resistor.
This multiplexing arrangement reduces the number of port pins used from eight to four. Firmware may easily use
either the LED or the switch for each port pin. When using both the LED and the switch on the same port pin,
firmware must momentarily toggle off the LED by writing a 1 to the pin’s port latch to read the push-button switch
status.
5.4. VBAT Selection Switch (SW5)
The UDP C8051F960/Si1020 MCU Card with Multiplexed LCD has many power options. The VBAT selector switch
(SW5) selects the power source for the main C8051F960/Si1020 VBAT supply pin.
The center VREG position selects the output of the on-board 3.3 V regulator (U1). 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.
The power sources for the on-board regulator (U1) are as follows:
9
V DC Wall Adapter power receptacle (P1).
USB receptacle (J17).
10-pin Debug connector (J13).
UDP motherboard +5 V (when connected).
The BATT position selects the ultra long life 3.6 V lithium thionyl chloride battery (BT1). This battery is a typical
power source for metering applications. The on-board regulator should be used primarily for development because
the battery has a limited peak current capacity.
Mini-B
The UDP position on the VBAT selector selects the UDP motherboard programmable supply (PWR_VDD_OUT) as
the power source for the UPPI Pico Board. Use this position when using the programmable power supply under
software control.
The UDP motherboard can also provide power to the on-board regulator. The VREG position will always work with
the motherboard, while the UDP switch position requires some motherboard configuration. The UDP motherboard
User’s Guide contains additional information.
The VBAT voltage and ground are available on test points in the top-left corner of the MCU card. Use these test
points to power the board from an external lab power supply. When using a lab supply, the VBAT selector switch
should be in the BATT position with the battery removed.
14
Rev. 0.2
C8051F96x/Si102x
5.5. Debug Header (J13)
The standard 10-pin debug header supports the Silicon Labs USB Debug Adapter. This connector provides a C2
debug connection to C8051F960/Si1020 on the UPPI Pico Board. 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.
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 VBAT switch must be in the VREG position. Additionally, select the Power Target
after the Disconnect check box in the Silicon Labs IDE connections options dialog to ensure the MCU always has
power.
5.6. Reset Button (SW6)
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 IDE disconnecting from the target.
5.7. Pin Power Supply Select Switches
The C8051F960/Si1020 MCU has two VIO pins: VIO and VIORF. These VIO pins set the logic level and drive
voltage for the MCU port pins. The VIORF pin sets the level for the port pins normally supporting radio functionality:
P1.5 through P2.3. The Si1020 P2.0-2.3 pins are connected internally to the EZRadioPRO. The VIO pin sets the
level for all other port pins.
5.7.1. VIORF Select Switch (SW12)
When using the dc-dc buck converter to power the radio, set the VIORF selector switch to the VDC position. This
connects the output of the buck converter to the VIORF pin. When using the Si1020, this switch also selects the
power source for the radio. In this position, firmware controls the voltage on the VDC pin. The C8051F960/Si1020
buck converter also has a bypass switch that can power the radio from the full supply voltage. The dc-dc buck
converter and bypass switch are off by default after an MCU reset, so the VDC pin voltage is floating until firmware
turns on the bypass switch or configures the dc-dc converter.
When the VIORF selector switch is set to the VBAT position, the VIORF pin connects via hardware to the VBAT
pin. In this position, the dc-dc buck converter cannot power the radio.
The VBAT position powers the VIORF pin without any firmware. This position is more convenient for simple code
examples. Use this position for the code examples provided unless otherwise indicated.
5.7.2. VIO Select Switch (SW7)
The VIO selector switch provides the same functionality as the VIORF switch for the main VIO pin. Normally this
switch should be in the VBAT position, which will set the drive and input levels of the pins to VBAT.
Setting the switch to the VDC position connects the VIO pin to the output of the buck converter. In this position, the
battery powers the MCU, and all of the I/O ports operate at a lower voltage set by the buck converter. This option is
best if most of the I/O pins connect to a low voltage radio or other low-voltage peripherals. Most applications should
use the VBAT position.
The C2 connection requires a VIO power source and VDC is not powered by default, so the VBAT position must be
used for initial development.
5.8. UART VCP Connection Options
The MCU card features a USB virtual COM port (VCP) UART connection via the mini-B USB connector (J17). The
VCP connection uses the CP2102 USB-to-UART bridge chip.
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 enables 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 P12 to connect P0.4 to MCU_TX and P0.5 to MCU_RX.
Rev. 0.2
15
C8051F96x/Si102x
If desired, install shorting blocks for hardware handshaking on P0.6 and P0.7 on the P12 header. Hardware
handshaking is not required for most applications. Firmware must implement hardware handshaking on the target
MCU using P0.6 and P0.7. The potentiometer and IREF current reference cannot be used on P0.6 and P0.7 if
firmware assigns these pins to hardware handshaking, and the shorting blocks on J18 and J19 should be removed.
The MCU card includes provisions to facilitate ultra-low power measurements. The UART pins of the target MCU
are completely disconnected from the USB-to-UART bridge by removing all the shorting blocks on P2. The VIO
supply powers the level translator. To remove the level-shifter current from the ultra-low power measurement, cut
the trace on the bottom of the board between the two pins of header J20. This will completely disconnect the level
translators from VIO. After cutting this trace, a shorting block is required on J20 to use the USB-to-UART bridge or
UDP UART connection.
5.9. Potentiometer (R34)
The potentiometer is available on P0.6. To use the potentiometer, install a shorting block on J18 to connect P0.6 to
POT. To facilitate a low-power potentiometer, P1.4 connects to bottom of the potentiometer as a potentiometer
enable (POT_EN). Drive P1.4 low to enable the potentiometer. Alternatively, install a 0 resistor for R35 to
continuously enable the potentiometer.
5.10. Pulse Counter Terminals (J14)
The MCU card includes a 4-position screw terminal connection. These field-wiring terminals will accept large wire
for a commercial water or gas meter. The PC0 and PC1 signals connect to P1.0 and P1.1 on the target MCU.
These are dedicated pins for the C8051F960/Si1020 low-power pulse counter. The VIO and ground connections
are also available for Form C meters. Refer to the C8051F960 data sheet for additional information about the pulse
counter.
5.11. Port Pin Headers (J9–J12)
All of the MCU port pins are available on the 0.100 inch headers on either side of the UPPI Pico Board.
Pins P1.2 and P1.3 are normally used for the RTC and are not connected by default to the P1.2 and P1.3 headers.
To use P1.2 and P1.3 for other purposes, remove the RTC crystal on the UPPI Pico Board and populate the two
small adjacent resistors with 0 resistors.
When using the Si1020 UPPI Pico Board, the SPI1 pins are connected internally and do not connect to the header
pins.

Rev. 0.2
C8051F96x/Si102x
5.12. MCU with Muxed LCD Board Default and Optional Connections
The MCU card has many default and optional connections for use with different radios and the UDP motherboard.
The default connections are via shorting jumpers. The shorting jumpers are a 603 resistor footprint with a cut trace
between pads. To disconnect, cut the trace with a sharp utility knife. To reconnect, install a 0 603 resistor or
connect the two pads with solder. The optional connections are non-populated (no-pop) resistor footprints. To
connect, install a 0 603 resistor or connect the two pads with solder.
When using the Si1020 UPPI Pico Board, some of the MCU port pins connect by default to EZRadioPRO port pins.
Note that plugging the UPPI Pico Board into the MCU card will connect some pins together.
Table 1 shows a summary of the default and optional connections for each pin.

UDP Motherboard Signal
Default
Optional
Optional
5.12.1. P0.0
Pin P0.0 connects to LED1/SW1 by default. Optionally, P0.1 can connect to the VREF capacitor. To use the VREF
instead of LED1/SW1, cut the trace on R1 and install a 0 resistor on R2.
5.12.2. P0.1
P0.1 normally connects to LED2/SW2. P0.1 can optionally connect to EZRP_TX_DATA_IN. To use
EZRP_TX_DATA_IN instead of LED2/SW2, cut the trace on R3 and install a 0 resistor on R4.
5.12.3. P0.2
Pin P0.2 normally connects to LED3/SW3. Optionally, P0.2 connects to EZRP_RX_CLK_IN. To use
EZRP_RX_CLK_IN instead of LED2/SW2, cut the trace on R5 and install a 0 resistor on R6.

Rev. 0.2
C8051F96x/Si102x
5.12.4. P0.3
Pin P0.3 connects to either LED4/SW4 or SPI_LCD_NSS, selected by J16. SPI_LCD_NSS is the SPI slave select
when using the Graphic LCD I/O card with the UDP Motherboard and this C8051F96x MCU card.
5.12.5. P0.6
P0.6 connects to either the potentiometer (POT) or EZRP_I2C_SDA, selected by J18. This signal supports I2C
radios using the 40-pin radio connector on the UDP motherboard. Removing the shorting jumpers from J18 and
populating R7 connects P0.6 to the EZR_ARSSI signal. This signal supports EZRadio transceivers using the 40pin radio connector on the UDP motherboard.
5.12.6. P0.7
Pin P0.7 connects to either the IREF0 current reference or EZRP_I2C_SCL, selected by J19. This signal supports
I2C radios using the 40-pin radio connector on the UDP motherboard. Removing the shorting jumpers from J19
and populating R8 connects P0.7 to the EZR_CLK_IN signal. This signal supports EZRadio transceivers using the
40-pin radio connector on the UDP motherboard.
5.12.7. P1.4
P1.4 normally connects to the potentiometer enable (POT_EN) signal. P1.4 can optionally connect to
RF_EBID_NSS, which allows the C8051F960 UPPI Pico Board to access the EBID on the 40-pin radio card. To
use RF_EBID_NSS instead of LED2/SW2, cut the trace on R9 and install a 0 resistor on R10.
5.12.8. P1.5
Pin P1.5 connects to GPIO_1 via R11 and R21 by default. To disconnect these signals, cut the trace on R11. This
signal supports the clear-to-send (CTS) signal for EZRadioPRO.
5.12.9. P1.6
P1.6 normally connects to nIRQ through R12. Cut the trace on R12 to disconnect these signals. P1.6 also
connects to nIRQ on the UPPI Pico Board, so a trace must also be cut on the UPPI Pico Board.
5.12.10. P1.7
Pin P1.7 normally connects to SDN via R13. To disconnect these signals, cut the trace on R13. Note that P1.7 also
connects to SDN on the UPPI Pico Board. Therefore, it is necessary to also cut a trace on the UPPI Pico Board.
5.12.11. P2.0 through P2.2
P2.0 through P2.3 connect internally on the Si1020.
For the C8051F960 UPPI Pico Board, pin P2.0 connects to SPI_LCD_SCK via R14, P2.1 connects to
SPI_LCD_MISO via R15, and P2.2 connects to SPI_LCD_MOSI through R16 by default. When the MCU card is
connected to a UDP motherboard, these signals support the Graphic LCD I/O card.
In addition to the Graphic I/O LCD signals, these pins also support the EZRadioPRO SPI interface on the UDP
motherboard.
These pins can also optionally be used as SPI connections for reading the 40-pin radio test card EBID by
populating the R17, R18, and R19 pads with 0 resistors.
5.12.12. EZRadio GPIO Signals
When using a Si1020 UPPI Pico Board, the four EZRadioPRO GPIO signals connect to the SMA connectors on
the motherboard.
GPIO_0 connects to EZRP_TX_DATA_IN via R20. This signal supports direct mode TX input data from an external
source using the SMA connector.
GPIO_1 connects to EZRP_RX_DOUT via R21. This signal supports direct mode RX data out of the SMA
connector. Normally, the RX data out is used with the RX clock out.
GPIO_2 connects to EZRP_RX_CLK_OUT via R22. This signal supports direct mode RX data out of the SMA
connector.
ANT_A connects to EZR_CLK_IN using R23. This provides a connection to the forth SMA connector. Cut the trace
on R23 when using an external 10 MHz clock with EZRadio.

6. Using the C8051F96x with the UDP Motherboard
6.1. VBAT Selector Switch
When used with the UDP Motherboard, the motherboard can power the C8051F96x 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
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 UDP C8051F960/Si1020 MCU Card with Multiplexed LCD 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 UDP C8051F960/Si1020 MCU Card with Multiplexed LCD card implements the signals described in Table 3,
Table 4, Table 5, and Table 6 in the Appendix.

6.3. Shorting Blocks: Factory Defaults
The UDP C8051F960/Si1020 MCU Card with Multiplexed LCD MCU Card comes from the factory with preinstalled shorting blocks on several headers. Figure 11 shows the positions of the factory default shorting blocks.
Figure 11. Shorting Blocks: Factory Defaults
Shorting blocks are installed on P2 to connect P0.4 to MCU_TX and P0.5 to MCU_RX. A shorting block is installed
on J16 to connect P0.3 to LED4/SW4/LED4. Shorting blocks are installed on J19 to connect P0.7 to IREF and on
J18 to connect P0.6 to POT.
