SPI Ctrl SFR Modem I/O Interfaces Figure 1 ZM2102 Z-Wave Module Block Diagram The ZM2102 Z-Wave Module contains a system crystal, why no external crystal is needed. In order to get a high reliable and high performance RF communication, the RF Front-end has an optimized and throughout tested matching circuitry, a narrow band SAW filter dedicated for Z-Wave communication and there are filtering of the RF circuitry supply voltage. The ZM2102 Z-Wave Module is connector-less using Castellation Notches for easy mounting of the module to an OEM Application PCB. The ZM2102 Z-Wave Module has a top shield that improves noise immunity of the module and enables the module to be mounted by a standard pick-and-place machine on the production line. The Z-Wave Protocol is designed to enable automatic network address assignment at installation, and simple inclusion/exclusion of nodes. These protocol-handling techniques ensure easy installation, expansion, and management of the Z-Wave control network. Furthermore each Z-Wave network has its own unique Network Identifier preventing control problems or interference from neighboring networks. The Z-Wave Protocol has a well-defined Application-Programming-Interface (API) enabling easy and fast Application SW development.

A detailed description of these signals is given in the ZW0201 Z-Wave Single Chip datasheet [1]. 1.3 1.3.1 RF Front-End RF input/output The ZM2102 Z-Wave Module is equipped with a SAW filter that rejects the unwanted frequencies both in receive and transmit operations.

As the ZM2102 Z-Wave Module is integrated into various products, different types of antennas can be implemented to get the best RF performance, i.e. range and reliability. In [4], a good overview of the Zensys A/S Product Description CONFIDENTIAL Page 5 of 14 DSH10229-11-11 ZM2102 Z-Wave Module Datasheet 2006-11-10 different antennas is given as well as their pro's and con's. In the case the antenna is not 50ohm a matching network must be implemented between the ZM2102 Z-Wave Module and the antenna. The matching network can for example be a "pi" or a "T" structure as shown in Figure 4.

Two decoupling capacitors should be placed at the VCC pin (EP11) a 4.7uF and a 100nF capacitor is recommended. The two capacitors should be placed as close EP11 as possible and the capacitor should be placed between the ZM2102 Z-Wave Module and the via that goes to the power plane as shown in Figure 7. Figure 7 Placement of decoupling capacitor (power pin, EP11) Zensys A/S Specifications CONFIDENTIAL Page 11 of 14 DSH10229-11-11 2.9.2 ZM2102 Z-Wave Module Datasheet 2006-11-10 Ground Plane In order to minimize any noise coupling from noisy signals (typically power products) it is recommended to insert as much ground cobber below the ZM2102 Z-Wave Module as possible on the Application PCB. 2.9.3 Antenna Interconnection As the RF signal (EP18) is 50ohm the trace from the EP18 to the matching circuitry (see 1.3.2) must be 50ohm. The Application PCB designer must therefore take the PCB layer structure and thickness into account when designing the 50ohm trace (either Microstrip or Stripline). Zensys A/S Specifications CONFIDENTIAL Page 12 of 14 DSH10229-11-11 ZM2102 Z-Wave Module Datasheet 2006-11-10 3 SOFTWARE 3.1 SPI Interface The signals `P1.2/MISO', `P1.4/SCK' and `P1.3/MOSI' signals are in some SW API's used by the protocol to store Routing Tables and HomeID in an external EEPROM. When these SW API's are used, the Application SW must not use these three signals. Table 9 shows the available SW API's and in which the SPI interface is used by the protocol. SW API SPI interface used by Protocol Slave No Routing Slave No Enhanced Slave Yes Controller Yes Static Controller Yes Installer Yes Bridge Yes Table 9 SW API / SPI availability 3.2 EEPROM Some SW API's require an external EEPROM to be implemented on the Application PCB for protocol information storage (like routing table, HomeID etc.). The SPI interface is used to access the EEPROM and the `P1.5' signal (EP5) is used by the Z-Wave Protocol as EEPROM Chip Select. To assure proper control of the EEPROM chip select signal during reset and power-up a pull up resistor on the P1.5 should be implemented as shown in Figure 8. +3.3 R1 10k +3.3 U1 P1.5 MOSI MISO SCK 8 1 3 7 5 2 6 4 VCC CS WP HOLD SI SO SCK GND C1 33nF AT25128N Figure 8 External EEPROM Only a part of the EEPROM is used for protocol data storage, the Application SW can use the remaining memory area using an API call (see [3]). For the EEPROM memory area requirements of the protocol API please refer to the documentation for the Z-Wave Controller code selected (see [3]).
