1 INTRODUCTION 1.1 PURPOSE The purpose of this document is to provide the product manual and Design Specifications for low power ZigBee (LPZigBee) module. 1.2 SCOPE The scope of this document is to produce the detail design of LPZigBee module. 1.3 INTENDED AUDIENCE This document is intended primarily for the EE Hardware Design. 1.4 DEFINITIONS AND ABBREVIATIONS Term Meaning ADC Analog to Digital Converter GPIO General Purpose Input/Output I2C Inter Integrated Circuit JTAG Joint Test Action Group FEM Front-end module SPI Serial Peripheral Interface UART Universal Asynchronous Receiver Transmitter NF Noise figure LPZigBee Low power Zigbee Module
2 OVERVIEW LPZigBee module mainly consists of three sections: the microcontroller ATXmega256D3 and periphery, the radio transceiver AT86RF231 and the RF front-end with power amplifier and low-pass filtering. The ATXmega256D3 controls the AT86RF231 radio transceiver and serves as an SPI master. The radio transceiver handles all actions concerning RF modulation/demodulation, signal processing, frame reception and transmission. MAC hardware acceleration functions are implemented in the radio transceiver, too. Further information about the radio transceiver and the microcontroller are available in the appropriate datasheets, refer to 1.5 references. The RF front-end incorporates signal amplification and filtering of the transmit signal. The degree of filtering depends on operating conditions as well as regional aspects. Switching between reception and transmission is directly controlled by the radio transceiver.

5 BLOCK DIAGRAM AND PORT FUNCTION 5.1 UART PORT LPZigBee Module provides four signals (RX, TX) of standard RS-232 protocol to support user applications. The UART port is set the DCE port and connected with other devices by D-Sub-9 Female connector. But the RX, TX connection between RS-232 Transceiver and D-Sub-9 Female connector can be reversed by Jumpers, allowing use of connecting straight-though or cross-wires cable. 5.2 PROGRAMMING AND DEBUG PORT The LPZigBee module can be programmed and debugged by JTAG port. It is a 20 pins header and connects with Atmel’s debugging tool. 5.3 GPIO PORT The GPIO connectors provide the SPI, I2C, UART and GPIO interface for external system testing. The recommended operation voltage is +3.3Vdc.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The transmitter module may not be co-located with any other transmitter or antenna, As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users. The final end product must be labeled in a visible area with the following: “Contains FCC ID: ZAR-TGPBA0010290”. Manual Information To the End User The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
