APEX/APEX LT DATASHEET

ZigBee Ready Modules

1 Product Description

The LS Research APEX and APEX LT modules are 2.4 GHz 802.15.4 data transceivers

providing a cost-effective solution for data links and wireless networks.

The APEX module is based on the Ember EM250 802.15.4/Zigbee platform and supports

point to point, point to multi-point, and EmberZNet applications. It provides a true Zigbee

module combining an IEEE 802.15.4 compliant radio transceiver with a 16-bit microprocessor.

The APEX LT module is based on the Ember EM260 Zigbee network processor providing an

IEEE 802.15.4 compliant radio transceiver with a SPI based interface to an application

microprocessor, giving the flexibility to choose the external microprocessor size to best fit the

application.

Both APEX and APEX LT utilize a 100mW power amplifier, providing for enhanced range

performance over standard 802.15.4/Zigbee implementations. The APEX modules offer a

standard integrated PCB trace antenna. Alternatively, each module has the option to be

populated with a MMCX connector for use with an external cabled antenna.

The hardware design files can be licensed from LS Research or LS Research can modify the

hardware to accommodate specific application requirements. The APEX modules provide a

low cost, best in class performance, in a compact form factor.

APEX/APEX LT The APEX module contains 16 GPIO ports that are shared with other peripheral or alternate functions. The alternate functions can be utilized on a variety of different GPIOs as detailed in the following table of pin assignments and definitions. All the GPIO pads are selectable as input, output, or bi-directional and have an internal pull-up or pull-down. The integrated Serial Controller SC1 can be configured for SPI (master-only), I2C (masteronly), or UART functionality.

APEX/APEX LT 9 Antenna The APEX and APEX LT modules include an integrated PCB trace antenna. An optional configuration with a MMCX connector is also available. This will enable connector to a 50ohm external antenna of the user’s choice. The integrated PCB antenna topology is an F-antenna. This antenna is used because it is reasonably compact, has a fairly omni-directional radiation pattern, good efficiency, and is very simple. An adequate ground plane is necessary to provide good efficiency.

APEX/APEX LT Keep out areas APEX/APEX LT The footprint recommends the APEX/APEX LT module is to be mounted so the antenna is overhanging the board edge. This will provide the best antenna performance for the PCB trace antenna. It is also recommended to have a ground plane on the host board underneath the rest of the module, up to the recommended PCB edge. This will only improve the antenna performance by increasing the overall ground plane.

APEX/APEX LT 12 Agency Certifications FCC Part 15.247 Module Certified (Mobile) The APEX and APEX LT modules comply with Part 15 of the Federal Communications Commission rules and regulations. To meet the FCC Certification requirements, the user must meet these regulations. • The text on the FCC ID label provided with the module is placed on the outside of the final product. • The modules may only use the antennas that have been tested and approved with this module.
PAGE 14
APEX/APEX LT is responsible for passing the additional FCC part 2.1093 rules (SAR) and FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields, OET Bulletin and Supplement C. The labeling requirements for Industry Canada are similar to those of the FCC. A visible label on the outside of the final product must display the IC labeling. The user is responsible for the end product to comply with IC ICES-003 (Unintentional radiators).

APEX/APEX LT 13 Shipment, Handling, and Storage 13.1 Shipment The LS Research APEX Modules are delivered in single piece, or 50 piece cartons in individual anti-static bags. 13.2 Handling The APEX/APEX LT Module is designed and packaged to be processed in an automated assembly line. ! Warning - The Modules contain highly sensitive electronic circuitry. Handling without proper ESD protection may destroy or damage the module permanently.

APEX/APEX LT 14.2 Reflow Soldering A convection soldering oven is recommended over the infrared radiation type oven. Convection ovens allow more precise temperature control, and more even heating of parts regardless of material composition, thickness, or color. Consider the IPC-7530 Guidelines for temperature profiling for mass soldering processes, reflow and wave, published 2001. 14.2.1 Preheat Phase Initial heating of component leads and solder paste balls, for removal of residual humidity.
PAGE 17
APEX/APEX LT The final choice of the soldering paste depends on individual factory approved manufacturing procedures. Stencil Thickness: 150 µm for host boards Note: The quality of the solder joints on the castellations (‘half vias’) where they contact the host board should meet the appropriate IPC specification. See IPC-A-610-12.2.4. 14.4 Cleaning In general, cleaning the populated modules is strongly discouraged. Residuals under the module cannot be easily removed with any cleaning process.
PAGE 18
APEX/APEX LT 14.9 Rework The APEX & APEX LT Module can be unsoldered from the host board. Use of a hot air re-work tool and hot plate for pre-heating from underneath is recommended. Avoid overheating. ! Warning - Never attempt a rework on the module itself, e.g. replacing individual components. Such actions will terminate warranty coverage. 14.
