Labs by presenting a complete 2.4GHz IEEE
802.15.4-2006 compliant wireless solution based
upon Silicon Labs EM35xx SOC and Qorvo’s
Top View
RFFM6204 FEM. Silicon Labs presents a fully
integrated system-on-chip (SoC) with a 32-bit
ARM® CortexTM-M3 microprocessor with flash
memory, and RAM memory, delivering unmatched
performance and EmberZNet PRO network
protocol stack to designers of ZigBee-based
systems. Qorvo presents the RFFM6204 world
class front end module (FEM) for efficient
extended output power at +14 dBm with harmonic
filtering, a low noise amplifier (LNA), a bidirectional
through mode path and a single balanced TDD
access. This document briefly describes the
RFFM6204EM357 reference design and how it is
set up and configured for Engineering Evaluation
of the RFFM6204 FEM using Silicon Labs nodetest application firmware, pre-flashed on the EM35xx SoC.
Reference Design Features:
 2.4 GHz IEEE 802.15.4-2003 transceiver & lower MAC
 +14 dBm transmit output power
 Small footprint 41.5mm x 21.59mm
 -104.5dBm Rx Sensitivity
Applications:

RFFM6204EM357 Reference Design
Board and Layout Descriptions
The RFFM6204EM357 reference design board is designed using FR-4 material. The RF section is coplanar with ground
(CPW) and the microstrip line target impedance is 50 Ω +/-5%. The target frequency is 2.5GHz and the dielectric constant is
4.26. The vias are thru-hole from layers 1 – 4. The stiching vias around the transmission line and antenna are nececssary to
prevent RF leakage and to improve isolation. The dimensions are 1634.858 x 851mils. It is highly recommended to follow
the reference design layout and PCB material and stack up for optimum performance. Please see the RFFM6204 (4) and
EM35x data sheets for the Stencil, Metal Land pattern and solder paste recommendations.

Evaluation and Configuration
The RFFM6204EM357 reference design is evaluated on the Ember EM35x breakout board (EM35X-BBRD) using an RS232 interface or USB interface with onboard RS-232 conversion. Power is provided using a USB supply, external supply, or
external battery pack. RF communications is made either over-the-air via the ceramic chip antenna (AT1) or J2 the coaxial
connector and switch (Murata P/N MM8130-2600RA2). A 2-megabit DataFlash® is provided for external serial-interface
Flash memory EEPROM. A 10-pin Insight port is provided for JTAG debugging.

RFFM6204EM357 Reference Design
With the RFFM6204EM357 reference design powered and connected to a PC, a terminal emulator can establish
communication with the appropriate RS-232 COM Port or USB interface, depending on which type of connection is in use. If
you do not have the proper FTDI drivers installed, please go to www.ftdichip.com/FTDrivers.htm and install the drivers for
your operating system. These drivers are needed to establish communication. Note that these drivers may have to be
installed twice to ensure proper operation. After connection is established with that port, set field values as follows:
After choosing the appropriate COM port the bits per second field should be 115,200; the data bits field should be 8; the
parity field should be none and the stop bits should be 1 with flow control set to Hardware. Pressing "Enter" will then
establish a response from the EM35xx SoC and configuration of the RFFM6204 FEM can now occur.
TOKEN_MFG_PHY_CONFIG Programming.
Before custom firmware is downloaded onto the EM35xx be sure to update the CIB token “TOKEN MFG PHY CONFIG”
from 0xFFFF to 0xFFFB.
1. Connect the SiLabs ISA3 box to a PC via USB.
2. Connect the InSightPort on the ISA3 box to the Insight Port on the RFFM6204EM357 board via the ribbon.
3. Connect the RFFM6204EM357 board to the EM35xx Breakout Board and set the Target Power switch on
the ISA3 to INT.

6. Next, disconnect the USB cable from the ISA3 box and also the ISA3 box from the RFFM6204EM357
board.
7. Finally, connect the USB cable from the PC to the EM35xx Breakout Board, open the proper COM port, set
the Baud Rate to 115200 and press the enter key. This token change indicates that an external PA is
connected to the bi-directional RF path (3). See Figure

FEM Shutdown
When the nodetest command “shutdown” is entered, the system goes into a full deep sleep state. If only the FEM needs to
be shutdown then the FEM’s shutdown pin is controlled by EM357 (pin 36 – PB0). The below steps describe how to
shut down the FEM only.
Step
