5 Hardware description CC2430DB
Figure 1: CC2430DB overview
5.1 Powering CC2430DB
The CC2430DB can be powered in three different ways:
•2.5 mm DC jack connector. This connector is placed under the board. The centre pin
is used for the positive voltage. A 4-10V DC power supply should be used. The
onboard voltage regulator supplies 3.3V to the board.
•USB power. If the CC2430DB is connected to a USB socket on a PC, it will draw
power from the USB bus. The onboard voltage regulator supplies 3.3V to the board.
•Battery power. The CC2430DB includes a battery clip for two AA type batteries
If several power sources are connected, the CC2430DB will be powered from the supply that
supplies the highest voltage. The USB MCU is only powered when USB or DC jack power is
used.

Figure 2: Power switch setting
The Power Switch S3 must be set according to what power source is used. If DC jack or USB
power is applied, the switch should be set to the USB position. If the board is powered from
batteries, the switch should be set to the BATT position as shown in Figure 2. When either
DC power or batteries are used to power the board, the switch can be used as an on/off
switch.
When powering the CC2430DB from batteries, the CC2430 will work down to 1.8V. Please
note that when using USB, the voltage range is limited to 3.0V – 3.6V. The CC2430DB has
been designed for a temperature range of –40°C to +85°C.
5.2 USB Interface
The USB interface is used to interface to a PC to run the In-Circuit Emulator in the IAR
Embedded Workbench (IAR EW) and using SmartRF®Studio. The IAR EW can also be used
to reprogram the CC2430DB (see the IAR EW manual for more details).
Furthermore, it is also possible to reprogram the CC2430DB via the USB interface with the
Chipcon programming software, or to use the board for the Chipcon packet sniffer.
When connected to the USB port the CC2430DB is powered from the USB and no other
voltage supplies are required.
Please refer to the Chipcon Flash Programmer User Manual installed with SmartRF®Studio
for a detailed description of how to reprogram the CC2430DB.
5.3 User interface
The CC2430DB includes a joystick and a push button as user input devices, and two LEDs as
user output devices.
5.4 EEPROM
A 32Kbit EEPROM is included for non volatile storage of data that is frequently updated. The
EEPROM has 1 Million guaranteed write cycles.
5.5 Accelerometer
The accelerometer can be used to measure movements in 2 axes. It can also be used for tilt
measurements by measuring the earth’s gravitation. The accelerometer has a 20 ms start-up
time after power on. See the Analog Devices ADXL321 datasheet for details about the
accelerometer.
5.6 Potentiometer
The potentiometer controls the voltage on the analog input pin P0_7 of the CC2430. The
voltage, and thus the potentiometer position, can be measured with the CC2430 A/D
converter.

SWRU125 Page 6
5.7 Light sensor
A light dependent resistor (LDR) measures light level and gives an analog signal that is
measured by the CC2430 A/D converter. The light sensor resistance ranges from 5KΩ(light)
to 20MΩ(dark).
5.8 I/O connectors
The I/O connectors bring out all the signals from CC2430. These connectors allow easy
access to all CC2430 I/O pins. External circuitry can be connected to these connectors for
prototyping.

5.10Signal flow
The signal lines from the I/O connectors and the CC2430 run via 0Ωresistors to the various
peripherals on the CC2430DB. The peripherals can be disconnected from the CC2430 signal
pins by removing the 0Ωresistors. Please refer to Table 6 for a list of what resistors
correspond to which signals.

Figure 6: CC2430DB Signal flow

SWRU125 Page 10
6 Using CC2430DB for prototyping
The CC2430DB can be used for prototyping by programming the CC2430 with custom
applications. All I/O ports on the CC2430 are available on pin row header at the edge of the
board, and the USB interface can be used as In Circuit Emulator (ICE) interface allowing real
time in circuit emulation of the CC2430.
Table 6 on page 13 shows what pins on the MCU are used for various functions.
P6 and P7 pin-row connectors can be used to connect the CC2430DB to other PCB or
prototyping boards. See page 6 for the pin-out of these connectors.
0Ωresistors are included to isolate the CC2430 from the external components on the
CC2430DB. By removing these resistors, signals can be accessed on the pin headers. Refer
to section 5.10 and Table 6 for information about which pin corresponds to which resistor.
6.1 Debugging using the USB interface
The most common way to use the CC2430DB for development is to use the USB interface to
control the CC2430 on-chip In-Circuit Emulator. The USB interface supplies power to the
board, so there is no need for additional DC power or batteries. The USB interface can also
be used to program the CC2430 in circuit using the Chipcon programming software.
6.2 Debugging CC2430DB with the CC2430 debug connector
The CC2430DB can be used with the Chipcon packet sniffer or other applications that require
USB interface for communication with PC and debugging with an emulator simultaneously. In
these cases the SoC debug connector can be used for connecting the ICE. The
SmartRF04EB can be used as emulator interface with a cable from P14 “SoC debug/flash” on
SmartRF04EB to P8 “2430deb” on CC2430DB. See Figure 7 below. The jumpers between
pin 1-2, 3-4 and 4-5 on header P5 must be removed.
CC2430DB must be powered from battery, USB or DC jack when debugged from
SmartRF04EB.
Figure 7: CC2430 Debug Connector

SWRU125 Page 11
6.3 Low power operation
CC2430DB is designed for low power operation when running from batteries. Only the
CC2430 is powered in this mode, the USB MCU is not powered. The voltage to the peripheral
functions connected to the CC2430 is controlled by an I/O pin P1.2 (VDD_SW_CTRL) on the
CC2430. Table 4 lists the current consumption for each of the peripherals.
To obtain minimum current consumption with the CC2430DB, the VDD_SW_CTRL (P1.2)
output must be configured as output.
Figure 8: Voltage supply distribution
Table 4 below shows the current consumption for all modules and operation modes with 3.3V
supply voltage

Table 6: Pinout CC2430
The joystick output is coded as an analog voltage. This has been done in order to save the
number of pins required on the MCU to interface with the joystick. The push function of the
joystick is connected to a digital input pin.
6.4 Using the UART interface on the CC2430DB
The CC2430 UART interface port is accessible on the header connectors as 3.3V signals. An
RS232 driver circuit is required to connect the UART interface on CC2430DB to a serial port
on a PC. The RS232 port on a SmartRF04EB can be connected to the CC2430DB to allow
applications to interface to a PC serial port.
Table 7 shows the connection between the CC2430DB and the SmartRF04EB. Both the P8
(10-pin) connector and the P6 (20-pin) connector on the CC2430DB can be used, but only
one of them should be connected at the same time.

Table 7: CC2430ZDK to SmartRF04EB serial port connections
A jumper must be placed between pin 7 and pin 9 on the USB MCU debug connector P301
on the SmartRF04EB board. This will ensure that the Silabs USB controller does not force
any pins to erroneous levels.
To use the serial port on CC2430DB USART1 must be used on alternative location 2 in the
CC2430. Please see the CC2430 datasheet for instructions how to select serial port and
location. Using the SmartRF04EB will only work if the Silabs USB controller on the
CC2430DB is powered, i.e. the CC2430DB must be powered from a USB or DC jack.
