RC220x Quick Product Introduction The RC220x series of modules are specially designed to meet the IEEE 802.15.4 standard used by ZigBee and a variety of proprietary network protocols. Using the module together with the Chipcon / Figure 8 Wireless Z-stack or any other ZigBee network implementation makes it a powerful platform to build any ZigBee profile and application.

RC220x Frequently Asked Questions What is IEEE 802.15.4? It is a standard for low data rate wireless Personal Area Networks (PAN) focusing on low power, low cost and robustness. It defines a Physical layer (PHY) and a Medium Access Control layer (MAC) and is the basis for the open ZigBee protocol or proprietary protocols. What is ZigBee? ZigBee is an open global standard aimed for wireless network communication between devices in home control, industrial and building automation applications.

RC220x IEEE 802.15.4 The IEEE 802.15.4 standard, approved in May 2003, provides a worldwide standard for Personal Area Networks or short distance wireless networks for low data rate solutions with long battery life and very low complexity. It defines a Physical layer (PHY) and a Medium Access Control layer (MAC) and is the basis for the open ZigBee protocol or proprietary protocols.
PAGE 8
RC220x JTAG Interface The module offers a JTAG interface for Flash and EEPROM programming, as well as for debugging. Programming through the JTAG interface requires control of the four JTAG specific pins: TCK, TMS, TDI, and TDO. Control of the reset and clock pins is not normally required. To be able to use the JTAG interface, the JTAGEN Fuse must be programmed. The device is default shipped with the fuse programmed. For further information, please refer to the respective MCU data sheet.
PAGE 9
RC220x Power Management The ZigBee protocol allows End Devices to be powered down, while Routers must be powered all the time in order to handle packet routing. Battery operated devices should be End Devices in order to reduce the power consumption to a minimum. The module can be set in several sleep modes using the features of the MCU and turning off the RF transceiver. Sleep modes enable the application to shut down unused modules in the MCU, thereby saving power.

PAGE 11
RC220x Antenna and Range Considerations As an option the module is delivered with an integrated antenna (RC220xAT). This is highly recommended for most applications, as this gives a very compact solution containing all the critical RF parts within the module.
PAGE 12
RC220x The simplest antenna to use is the quarter wave whip antenna. A quarter wave whip antenna above a ground plane yields 37 Ohm impedance and a matching circuit for 50 Ohm are usually not required. A PCB antenna can be made as a copper track where the ground plane is removed on the back side. The rest of the PCB board should have a ground plane as large as possible, preferably as large as the antenna itself, to make it act as a counterweight to the antenna.
PAGE 13
RC220x PCB Layout Recommendations The recommended layout pads for the module are shown in the figure below (top view, pin 1 is in upper left corner, see pin assignment at page 4). All dimensions are in thousands of an inch (mil). The circle in upper left corner is an orientation mark only, and should not be a part of the copper pattern. The area underneath the module should be covered with solder resist in order to prevent short circuiting the test pads on the back side of the module.
