Circuit Description The module contains an IEEE 802.15.4 compliant RF transceiver, high speed oscillator, RC oscillator and RF FEM . The module is intended to running the Ember ZigBee software or other ZigBee network implementation, depending on the specific version. The application software together with the ZigBee protocol software stack can be programmed in Flash memory through SIF module, using an evaluation board from Ember InSight Desktop. To support user-defined applications, the module exposes the Ember Serial API over the SPI, which allows application development to occur on a Host microcontroller of choice. In addition to the four SPI signals, two additional signals, nHOST_INT and nWAKE, provide an easy-to-use handshake mechanism between the Host and the module. Also, an integrated voltage regulator, power-on-reset circuitry, sleep timer, and low-power sleep modes are available. The deep sleep mode draws less than 5μA allowing products to achieve long battery life.

CT-EM2606 ZigBee Ready RF Transceiver Modules Computime Ltd. All rights reserved Confidential 10 / 16 13. SIF Module Programming and Debug Interface SIF is a synchronous serial interface developed by Cambridge Consultants Ltd. It is the primary programming and debug interface of the CT-260. The SIF module allows external devices to read and write memory-mapped registers in real-time without changing the functionality or timing of the XAP2b core. The SIF interface provides the following:  IC production test (especially analog)  PCB production test  Firmware download  Product control and characterization The pins are:  SIF_LOADB  SIF_CLK  SIF_MOSI  SIF_MISO The maximum serial shift speed for the SIF interface is 48MHz. SIF interface accesses can be initiated even when the chip is in idle, deep sleep or power down modes. An edge on nSIF_LOAD wakes the chip to allow SIF cycles. 14. Power Management The module supports four different power modes: active, idle, deep sleep, and power down. Active mode is the normal, operating state of the module. While in idle mode, code execution halts until any interrupt occurs. All modules including the radio continue to operate normally. The EmberZNet stack automatically invokes idle as appropriate. Deep sleep mode and power down mode both power off most of the functions, including the radio, and leave only the critical chip functions powered. The internal regulator is disabled. All output signals are maintained in a frozen state. Upon waking from deep sleep or power down mode, the internal regulator is re_enabled. Deep sleep and power down result in the same sleep current consumption. The two sleep modes differ as follows: the module can wake on both an internal timer and an external signal from deep sleep mode; power down mode can only wake on an external signal.

RF Frequency Detail The following table shows the RF channels as defined by the IEEE 802.15.4 standard. RF channel Frequency 11 2405MHz 12 2410MHz 13 2415MHz 14 2420MHz 15 2425MHz 16 2430MHz 17 2435MHz 18 2440MHz 19 2445MHz 20 2450MHz 21 2455MHz 22 2460MHz 23 2465MHz 24 2470MHz 25 2475MHz 26 2480MHz The output power level of em250 can be configured in the range -32 to 3dBm and the gain of FEM is 17dB, So the module output can controlled in range -15 to 20dBm. The RF transceiver uses direct sequence spread spectrum (DSSS) with 2 Mchip/s chip rate, giving a raw data rate of 250 kbit/s. The modulation format is Offset – Quadrature Phase Shift Keying (O-QPSK). It is robust even under noisy environments when sharing the same frequency band with other applications. The use of RF frequencies and maximum allowed RF power should according to different national regulations. The CT-260 is complying with the applicable regulations for the world wide 2.4GHz ISM band. [Subject to final approval: Specifically it complies with the European Union R&TTE directive meeting EN 300 328 and EN300 440 class 2. It also meets the FCC CFR47 Part15 regulations for use in the US and the ARIB T-66 for use in Japan.]

An optional MMCX connector can be specified, enabling connection to a 50-ohm external antenna of the user’s choice.. The PCB antenna employs an F-Antenna topology that is compact and supports an omni-directional radiation pattern. To maximize antenna efficiency, an adequate ground plane must be provided on the host PCB. If positioned correctly, the ground plane on the host board under the module can contribute significantly to antenna performance. The position of the module on the host board and overall design of the product enclosure contribute to antenna performance. Poor design effects radiation patterns and can result in reflection, diffraction, and/or scattering of the transmitted signal. Here are some design guidelines to help ensure antenna performance: • Never place the ground plane or route copper traces directly underneath the antenna portion of the module. • Never place the antenna close to metallic objects. • In the overall design, ensure that wiring and other components are not placed near the antenna. • Do not place the antenna in a metallic or metallized plastic enclosure. • Keep plastic enclosures 1cm or more from the antenna in any direction.
