Datasheet
Integrated Z-Wave RF Module
The ZM2102 Z-Wave Module is a fully integrated RF
communication module that uses the unlicensed Short-RangeDevice (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.

Overview
The ZM2102 Z-Wave Module is a fully integrated module containing all the HW and SW required to
Z-Wave enable OEM products. The ZM2102 Z-Wave Module contains the Z-Wave ZW0201 Single Chip,
System Crystal, RF Front-end and RF Supply Voltage Filtering. Only the antenna needs to be

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.

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 made 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

matching network must be implemented between the ZM2102 Z-Wave Module and the antenna. The

The integrated Reset pull up is not for external circuitry. An external pull up resistor should be implemented.
The transceiver is in transmit mode with the MCU running. The ADC is off. The crystal is 32MHz.
The transceiver is in receive mode with the MCU running. The ADC is off. The crystal is 32MHz.
The ADC, transceiver, MCU and flash are shut down. The chip can be woken by brownout, an external reset
pulse, external interrupt (if enabled) or periodical wakeup by WUT (if enabled). POR cannot be disabled.

Application PCB Layout Recommendation
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.

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).

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.

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.
