Datasheet

Integrated Z-Wave RF Module

The ZM2102 Z-Wave Module is a fully integrated RF

communication module that uses the unlicensed Short-Range-

Device (SRD) frequency band of 868.42MHz in Europe and

908.42MHz in US. The ZM2102 is dedicated for wireless control

and monitoring of residential products like lighting and appliance

control, energy management, access control, security and building

automation.

Together with the patented Z-Wave Protocol the ZM2102 Z-Wave

Module delivers a complete highly reliable RF communication

solution. The Z-Wave Protocol uses Frame Acknowledgement,

Retransmission, Collision Avoidance, Frame Checksum Check and

sophisticated Routing to assure reliable full home coverage.

The ZM2102 Z-Wave Module contains the integrated ZW0201

Z-Wave Single Chip, system crystal and RF front-end circuitry. The

ZW0201 Single Chip is an integrated chip containing RF

Transceiver, 8051 MCU core, SRAM, Flash Memory for Z-Wave

Protocol and OEM Application software storage, Triac Controller

and a wide range of HW interfaces.

This complete RF solution makes it very easy for OEM customers

to RF enable their products without having to do the time

consuming work of designing, verifying and optimizing the RF

design and thereby enables faster time to market.

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 interferen ce from neighboring networks.

The Z-Wave Protocol has a well-defined Application-Programming-Interface (API) enabling easy and fast

Application SW development.

the ZW0201 Z-Wave Single Chip on the ZM2102 Z-Wave Module. A detailed description of these signals

is given in the ZW0201 Z-Wave Single Chip datasheet [1].

receive and transmit operations.

The RF input/output on the ZW0201 is a single ended input/output that is internally matched to 50 ohm.

1.3.2 Antenna Matching

The ZM2102 Z-Wave Module is using an antenna placed on the Application Module, the matching of the

external antenna to 50 ohm (SAW filter impedance) must be ma de on the Application Module.

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

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.

Figure 6 Recommended Reflow Temperature Profile

2.9 Application PCB Layout Recommend ation

2.9.1 Supply Voltage

As the ZM2102 Z-Wave Module contains a RF transceiver good supply voltage decoupling is important.

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.

Zensys A/S Specifications Page 12 of 14

CONFIDENTIAL

2.9.2 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 t he 50ohm trace (either Microstrip or Stri pline).

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.

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 sho wn in Figure 8.
