EFR32ZG14 Z-Wave 700 Modem SoC Data Sheet
System Overview
3. System Overview
3.1 Introduction
The Z-Wave 700 EFR32ZG14 is a serial modem device which takes advantage of Silicon Labs EFR32 SoC technology to provide a
low-power, high-performance Z-Wave gateway. The EFR32ZG14 consists of a simple serial port to communicate with the host controller, and a sub-GHz radio for RF communications to Z-Wave end devices. The Z-Wave protocol stack is fully implemented on chip, and
a simple serial API is used for data and control.
3.2 Power Configuration
The EFR32ZG14 is powered from a single external supply voltage. An on-chip DC-DC converter provides energy efficiency for the radio
and digital subsystems. On-chip supply monitors safely manage power-up, power-down, and brown-out conditions.
Typical power supply circuitry for the EFR32ZG14 is shown below. The main system supply should be attached to VREGVDD, AVDD
and IOVDD, while the DC-DC regulates the digital (DVDD) and radio (RFVDD) supplies.

3.2.1 Power Modes
The EFR32ZG14 uses different power modes during operation to minimize the energy consumed by the system. When the radio is
active, either listening, receiving, or transmitting, the EFR32ZG14 manages these power modes automatically, without requiring instruction from the host controller.
The host can also place the device into a low power standby state using the SUSPENDn pin. When standby is active, the radio and
serial interfaces are shut down and any RF connections are terminated. The system will re-establish communication when standby is
released.

System Overview
Optionally, a SAW filter bank can be added and controlled via the SAW0 and SAW1 output pins for operation in different regions. Table
3.1 SAW Filter Selection on page 7 details the logic output levels for different SAW filters.

Note: The state 1, 1 for SAW1, SAW0 is undefined.
Consult with Z-Wave Global Regions frequency list to identify country specific frequency and corresponding SAW filter.
In systems where switchable filtering is not required, SAW0 and SAW1 should be left unconnected, and the appropriate RF filtering
should be used.
3.4 Embedded Interface
A host controller communicates with the EFR32ZG14 using a serial API over a standard 115,200 baud UART serial interface, shown in
Figure 3.4 Host Interface Connections on page 7. The RESETn signal is an active-low reset which brings the EFR32ZG14 back to
its initial power-on state. An optional active-low SUSPENDn signal may also be used to place the EFR32ZG14 modem in a low power
mode when radio functions are not required. PTI_SYNC and PTI_DATA are for packet trace interface. PTI_SYNC and SUSPENDn
share the same pin (PB13), and both PTI function and SUSPEND function are disabled by default. Either one of them can be enabled
using serial API at runtime. The host may also supply a programming interface to update EFR32ZG14 firmware.

image that may be installed through a standard ARM SWD interface. The binary is available for download at https://www.silabs.com.

4.1 Electrical Characteristics
All electrical parameters in all tables are specified under the following conditions, unless stated otherwise:
• Typical values are based on TAMB=25 °C and VDD= 3.3 V, by production test and/or technology characterization.
• Radio performance numbers are measured in conducted mode, based on Silicon Laboratories reference designs using output power-specific external RF impedance-matching networks for interfacing to a 50 Ω source or load.
• Minimum and maximum values represent the worst conditions across supply voltage, process variation, and operating temperature,
unless stated otherwise.
Refer to for more details about operational supply and temperature limits.
4.1.1 Absolute Maximum Ratings
Stresses above those listed below may cause permanent damage to the device. This is a stress rating only and functional operation of
the devices at those or any other conditions above those indicated in the operation listings of this specification is not implied. Exposure
to maximum rating conditions for extended periods may affect device reliability. For more information on the available quality and reliability data, see the Quality and Reliability Monitor Report at http://www.silabs.com/support/quality/pages/default.aspx.

Note:
1. The maximum limit on TA may be lower due to device self-heating, which depends on the power dissipation of the specific application. TA (max) = TJ (max) - (THETAJA x PowerDissipation). Refer to the Absolute Maximum Ratings table and the Thermal
Characteristics table for TJ and THETAJA.
2. VREGVDD must be tied to AVDD. Both VREGVDD and AVDD minimum voltages must be satisfied for the part to operate.
3. The minimum voltage required in bypass mode is calculated using RBYP from the DCDC specification table. Requirements for
other loads can be calculated as VDVDD_min+ILOAD * RBYP_max.
4. The system designer should consult the characteristic specs of the capacitor used on DECOUPLE to ensure its capacitance value stays within the specified bounds across temperature and DC bias.
5. VSCALE0 to VSCALE2 voltage change transitions occur at a rate of 10 mV / usec for approximately 20 usec. During this transition, peak currents will be dependent on the value of the DECOUPLE output capacitor, from 35 mA (with a 1 µF capacitor) to 70
mA (with a 2.7 µF capacitor).

Note:
1. All dimensions shown are in millimeters (mm) unless otherwise noted.
2. This Land Pattern Design is based on the IPC-7351 guidelines.
3. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder mask and the metal pad is to be 60 µm
minimum, all the way around the pad.
4. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used to assure good solder paste release.
5. The stencil thickness should be 0.125 mm (5 mils).
6. The ratio of stencil aperture to land pad size can be 1:1 for all perimeter pads.
7. A 3x3 array of 0.85 mm square openings on a 1.00 mm pitch can be used for the center ground pad.
8. A No-Clean, Type-3 solder paste is recommended.
9. The recommended card reflow profile is per the JEDEC/IPC J-STD-020 specification for Small Body Components.
Note: Above notes and stencil design are shared as recommendations only. A customer or user may find it necessary to use
different parameters and fine tune their SMT process as required for their application and tooling.
