RF6555EM357 Reference Design The RF6555EM357 reference design builds upon the partnership between Figure 1. Top and Bottom view of RF6555EM357 Reference Design RFMD and Ember by presenting a complete 2.4GHz IEEE 802.15.4-2003 Top View compliant wireless solution based upon Ember’s EM35x SOC and RFMD’s RF6555 FEM. Ember presents a fully integrated system-on-chip (SoC) with ® 32-bit ARM CortexTM-M3 microprocessor, flash memory, and RAM memory, delivering unmatched performance and EmberZNet PRO network protocol stack to designers of ZigBee-based systems. RFMD presents a world class front end module (FEM) for efficient extended output power at 18dBm with harmonic filtering, diversity switch, and LNA option for "bypass mode". This Bottom View document briefly describes the RF6555EM357 reference design and how it is set up and configured for Engineering Evaluation of the RF6555 FEM using Ember's nodetest application firmware, pre-flashed on the EM357 SoC. Snapshots of Tx and Rx data are included. RF Micro Devices Inc. 7628 Thorndike Road, Greensboro, NC 27409-9421 For sales or technical support, contact RFMD at +1.336.678.5570 or [email protected].

Block Diagram of PER Test Setup Evaluation and Configuration The RF6555EM357 reference design is evaluated on the Ember EM35x breakout board (EM35x-BBRD) using an RS232interface or USB interface with onboard RS-232 conversion. Power is provided using a USB supply, external supply, or external battery pack. Figure 6.

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 EM357 SoC and configuration of the RF6555 FEM can now occur. Figure 7.

The max input signal level for the EM35x alone is 0dBm. A signal larger than this can damage the EM35x. In order to avoid incorrect receive operation of the EM35x the RF6555 should be placed in bypass mode for incoming signals greater than 0dBm to +6dBm. The EM35x has an ADC interrupt built inside which can generate a flag when the incoming RF signal exceeds the limits for a signed 16-bit number (gain saturation).
