ZGM230S Z-Wave 800 SiP Module Data Sheet

System Overview

3. System Overview

3.1 Block Diagram

The ZGM230S module is a highly-integrated, high-performance system in a package with all the hardware components needed to ena-

ble Sub-GHz wireless connectivity and support robust networking capabilities via the Z-Wave protocol.

Built around the EFR32ZG23 Wireless Gecko SoC, the ZGM230S includes a 50 Ω RF pin to attach an external antenna, a matching

network optimized for transmit power efficiency, supply decoupling and filtering components, an LC tank for DCDC conversion, and a

39 MHz crystal.

3.2 EFR32ZG23 SoC

The EFR32ZG23 SoC features a 32-bit ARM Cortex M33 core, a Sub-GHz high-performance radio, 512 kB of Flash memory, a dedica-

ted core for security, a rich set of MCU peripherals, and various clock management and serial interfacing options. Consult the

EFR32xG23 Reference Manual and the EFR32ZG23 Data Sheet for details.

3.3 Antenna

The ZGM230S modules include a 50 Ω-matched RFIO pin to attach an external antenna to the module.

3.4 Power Supply

The nominal supply level of the ZGM230S is 3.3 V, but due to its integrated DCDC converter and built-in LDOs, the device can operate

over a supply range of 1.8—3.8 V.

Only a few external decoupling capacitors are required (see Reference Diagrams). Since all smaller caps are integrated in the module,

there is no need for fast decoupling externally. L and C for the DCDC converter are integrated in the module as well.

3.5 Security

ZGM230S modules support one of two levels in the Security Portfolio offered by Silicon Labs: Secure Vault Mid or Secure Vault High.

Secure Vault is a collection of technologies that deliver state-of-the-art security and upgradability features to protect and future-proof

IoT devices against costly threats, attacks and tampering. A dedicated security CPU enables the Secure Vault functions and isolates

cryptographic functions and data from the Cortex-M33 core. ZGM230SB part numbers support Secure Vault High and ZGM230SA part

numbers support Secure Vault Mid.
