5 SmartRF04EB

This chapter includes overall information that applies to SmartRF04EB. In the following SoC

means Chipcon System on Chip, i.e. CC1100, CC2510, or CC2430.

Figure 1: Main components

Figure 1 shows the main components on the SmartRF04EB. A USB cable from a PC is

connected directly to the Silabs USB controller. When a SoC evaluation module is pulged

into the SmartRF04EB, the only purpose of the USB controller is to “translate” USB signals to

the SoC 2-wire debug interface. This interface includes Debug Clock (DC) and Debug Data

(DD). The USB controller also controls the reset_n line connected to the SoC.

Most of the peripherals on the SmartRF04EB are connected to both the Silabs USB controller

and to the SoC. This means that I/O ports on both controllers can drive the same pin. When

the Silabs controller detects that a SoC is connected, it will therefore set all the I/O in three-

state (high impedance) mode. The connection to the Silabs USB controller may anyhow

somewhat influence these I/O lines.

5.1 Silabs USB MCU

5.1.1 Bootloader

The Silabs USB controller is programmed with a bootloader when it is shipped from the

factory. The bootloader allows programming of new code into the USB MCU without the

Silicon Labs’ serial adapter. The bootloader communicates with SmartRF®Studio or a custom

program via USB.

5.1.2 Programming Silabs USB controller

If it is required to update the firmware of the USB MCU, this can be done using the

SmartRF04 programming software (Chipcon Flash Programmer or SmartRF Studio). For use

of Chipcon Flash Programmer please refer to Chipcon Flash Programmer user manual for

instructions. The Silabs controller can only be updated via USB when no EM is connected to

the SmartRF04EB.

To download firmware to the Silabs USB MCU without using the bootloader or to download

the bootloader in the first place, a Silicon Labs’ EC2 serial adapter (Figure 2) is required. This

adapter should be connected to P301, marked “USB MCU debug”, on the SmartRF04EB.

As mentioned in the table, the joystick output is coded as an analogue voltage. This has been

done in order to save the number of pins required on the MCU to interface with the joystick.

The SoC software libraries contain functions to decode the ADC values and indicate in what

direction the joystick is moved. The push function of the joystick is treated as a separate

digital signal.

Figure 3: SmartRF04DK overview

The figure above shows the major parts of the SmartRF04EB. The SmartRF04EB serves as

main platform in the development kit.

CC1110/CC2430/CC2510

6.1 Powering SmartRF04EB

If several power sources are connected to SmartRF04EB the board will be powered from the

supply that supplies the highest voltage.

Figure 4: Power switch setting

The Power Switch S3 must be set according to what power source is used. If 3.3V is applied

using the power terminal block, the switch should be set to the left position. In all other cases,

the switch should be set to the right position for power to be applied to the SmartRF04EB.

This switch can be used to turn off the SmartRF04EB by switching it to the opposite position

of that used to turn it on.

Figure 5: Power connector

The 4-10V input is used for powering the SmartRF04EB using the on-board voltage regulator.

0V is the ground connection. The 3.3V terminal is used for powering the SmartRF04EB,

bypassing the on-board voltage regulator. A voltage between 2.7 and 3.6V can be used when

USB is not active, when using USB the voltage should be limited to 3.0-3.6V.

The SmartRF04EB can be powered in several different ways:

•DC jack connector with standard DC jack power connectors with a 2.5mm centre pin. 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.

•Laboratory power supply. Ground should be connected to the 0V terminal on the power

connector (see Figure 5). A 4-10V supply can be connected to the “4-10V” terminal, or a

3.3V supply can be connected to the “3.3V” terminal (the on-board voltage regulators will

be bypassed in this case). If a 3.3V supply is used, the supply selection switch should be

set to the “3V” position, otherwise the “4-10V” position should be used. If the “4-10V”

position is selected, a voltage regulator supplies the circuitry on the SmartRF04EB;

otherwise the 3.3V supply is applied directly to the SmartRF04EB.

•USB power. If the SmartRF04EB 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 evaluation board includes a 9V-type battery connector on the bottom

side of the PCB. A 9V battery or a battery pack that uses a 9V-type connector can be

SWRU039B Page 9 of 28

CC1110/CC2430/CC2510

connected to this battery connector. The onboard voltage regulator supplies 3.3V to the

board.

Please note that while the SmartRF04 devices have a wide supply range, the components on

the SmartRF04EB limit the total voltage supply range to 2.7V – 3.6V (3.0V – 3.6V while the

USB is active). The SmartRF04EB has been designed for a temperature range of –40°C to

+85°C (excluding the LCD display). The EM is designed for a temperature range of -40°C to

+85°C.

6.2 USB Interface

The USB interface is used to interface to a PC to run SmartRF®Studio and for programming

and debugging using the PC debugging tools and programmers. If SmartRF®Studio connects

to the SmartRF04EB and detects an old version of the USB MCU firmware, the USB MCU will

be upgraded via this interface. The SmartRF04EB can be bus-powered from the USB

interface.

6.3 RS-232 interface

The RS-232 can be used by custom applications for communication with other devices. The

RS-232 interface utilises a voltage translation device so that the RS-232 port is compatible

with bipolar RS-232 levels.

Note that this RS-232 level converter contains a charge-pump power supply that generates

electric noise.

6.4 User interface

The SmartRF04EB includes a joystick and a push button as user input devices, and four

LEDs and a 2x16 character LCD display as user output devices. The display and user

interface is by default controlled by the factory firmware in the SoC.

6.5 Audio interface

The SmartRF04EB includes a microphone input and headphone output.

The audio output section consists of a volume control, followed by a 4th order Chebychev

filter. This filter serves to attenuate frequencies above 6 kHz, and so converts the PWM signal

to an analogue audio signal. A headphone amplifier IC (TPA4411 from Texas Instruments) is

used to drive the headphones.

Note that the headphone amplifier IC uses switch-mode power supply techniques to generate

negative voltages, and this may cause electrical noise. The headphone amplifier can be

disabled by driving a pin on the USB MCU low (the same pin is used to disable the RS-232

voltage converter).

The audio input section consists of a microphone amplifier that also includes a low-pass anti-

aliasing filter.

A standard PC-type headset with separate microphone and headphone mini-jacks can be

connected directly to the audio interface.

6.6 SPI interface swap jumpers on SmartRF04EB

Due to a bug in early revisions of some of the SoC’s, the MISO and MOSI pins changed

directions when switching between SPI slave and master modes. For newer revisions of the

chip, the SPI jumper should always be in master mode position. The default settings of the

jumpers are SPI master mode, see Figure 6. SPI slave mode is used by the Chipcon packet

sniffer.
