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
R
ec
om
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:
N

R
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.
N
ot
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.

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.

C8051F96x/Si102x
5.2. Push-Button Switches and LEDs (SW1–SW4, LED1–LED4)
The UDP C8051F960/Si1020 MCU Card with EMIF has four push-button switches. The four switches connect to
P3.0 through P3.3. The switches are normally open and pull the pin voltage to ground when pressed.
es
ig
ns
Port pins P3.0 through P3.3 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.
5.3. VBAT Selection Switch (SW5)
D
The UDP C8051F960/Si1020 MCU Card with EMIF has many power options. The VBAT selector switch (SW5)
selects the power source for the main C8051F960/Si1020 VBAT supply pin.
N
ew
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
m
en
de
d
fo
r
V DC Wall Adapter power receptacle (P1).
Mini-B 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.
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.
om
5.4. Debug Header (J13)
ec
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.
N
ot
R
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 Disconnect check box in the Silicon Labs IDE connections options dialog to ensure the MCU always has
power.
5.5. 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 the IDE disconnecting from the target.

5.6. Pin Power Supply Select Switches
es
ig
ns
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.
D
5.6.1. 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.
N
ew
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.
5.6.2. 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.
fo
r
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.
m
en
de
d
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.
5.7. 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.
om
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.
ec
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. These pins also connect to the 40-pin radio card I2C signals by default. If necessary,
disconnect these signals by cutting the traces on R9 and R10.
N
ot
R
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 P12. 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.

5.8. Potentiometer (R50)
The potentiometer is available on P1.4. To facilitate a low-power potentiometer, P2.7 connects to bottom of the
potentiometer as a potentiometer enable (POT_EN). Drive P2.7 low to enable the potentiometer. Alternatively,
install a 0 resistor for R51 to continuously enable the potentiometer.
es
ig
ns
5.9. 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.

The C8051F96x MCU card has many default and optional connections for use with different radios and the UDP
motherboard. The default connections have shorting jumpers consisting of a 603 resistor footprint with a trace
between the pads. To disconnect a default connection, cut the trace between the pads. 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 to EZRadioPRO port pins by default.
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.

5.11.1. P0.0 through P0.3
Pins P0.0 through P0.3 connect to the UDP SPI_LCD signals (SPI_LCD_SCK, SPI_LCD_MISO, SPI_LCD_MOSI,
SPI_LCD_NSS) by default. These signals support the optional Graphical LCD display I/O card when used with the
UDB motherboard. To disconnect these default connections, cut the traces on R1 through R4. Optionally, these
signals can also connect to the EBID SPI on the 40-pin radio card. R8 provides an option to use P0.0 as a voltage
reference.
fo
r
5.11.2. P0.6
Pin P0.6 connects to EZRP_I2C_SDA by default. This signal supports I2C radios and EZRadio transceivers using
the 40-pin radio connector on the UDP motherboard.
m
en
de
d
5.11.3. P0.7
Pin P0.7 connects to EZRP_I2C_SCL by default. This signal supports I2C radios using the 40-pin radio connector
on the UDP motherboard. The MCU card provides optional connections to connect P0.7 to EZRP_RX_CLKOUT or
use P0.7 as the IREF current reference pin.
5.11.4. P1.4
Pin P1.4 normally connects to the potentiometer. Optionally, P1.4 can connect to EZR_ARSSI. This signal supports
an analog RSSI measurement using an EZRadio 40-pin test card.
5.11.5. P1.5
Pin P1.5 connects to GPIO_1 via R15 and R29 by default. To disconnect this signal, cut the trace on R15. This
signal supports the clear-to-send (CTS) signal for EZRadioPRO.
om
5.11.6. P1.6
Pin P1.6 normally connects to nIRQ using R17. Cut the trace on R17 to disconnect these signals. Note that P1.7
also connects to nIRQ on the UPPI Pico Board, so a trace on the UPPI Pico Board must also be cut.
ec
5.11.7. P1.7
Pin P1.7 connects to SDN via R18. To disconnect these signals, cut the trace on R18. P1.7 also connects to SDN
on the UPPI Pico Board, so it is necessary to also cut a trace on the UPPI Pico Board.
R
5.11.8. P2.4
P2.4 normally connects to the PIEZO signal. This signal drives a piezo transducer on the graphical LCD I/O card.
N

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
es
ig
ns
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
N
ew
D
The C8051F96x 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 EMIF 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:
