Introduction to Z-Wave 800 Series - Silicon Labs (2024)

The Z-Wave 800 series is the latest edition of the world’s most popular Z-Wave wireless IoT mesh protocols for smart homes. The Z-Wave 800 series enables device makers to develop exceptional smart home experiences through reliable Sub-GHz wireless, robust security, battery friendly power consumption, and easy Smart Start commissioning. The Silicon Labs ZG23 and ZGM230S hardware are the most secure Sub-GHz wireless solution featuring the Z-Wave 800 wireless mesh protocol. The Z-Wave 800 series is designed to meet the demands of smart home, hospitality, and multi-dwelling unit (MDU) IoT segments today and in the future. It is an optimal wireless protocol for applications where long-range, high performance, low power, and increased device security are vital – these include smart lighting, thermostats, door locks, garage door openers, switches, home cameras, sensors and more.

Z-Wave 800 Series Hardware

The sub-GHz solutions from Silicon Labs provide long-range connectivity that can penetrate walls, effectively reducing interference. The solution enhances IoT end node performance by optimizing power consumption, processing, and wireless range.

The ZG23 SoCs and ZGM230S modules provide the most secure sub-GHz wireless solutions featuring Z-Wave S2 and Silicon Labs’ proprietary Secure Vault™ security suite, enabling the first wireless solutions with the highest PSA Certification Level 3 security. This ensures protection of connected smart home products, data, IP, and users against constantly evolving security threats.

Some other key highlights are:

  • Low sleep and active currents for MCU and radio, enabling 50% longer battery life than Z-Wave 700 series.
  • Up to 10 years of coin cell battery life.
  • Industry-leading ARM Cortex-M33 microprocessor delivering ~20% more processing power than Cortex-M4.
  • Z-Wave Long Range (LR), enabling wireless range beyond 1.5 miles.

The ZG23 and ZGM230S series are backward compatible with their predecessor Z-Wave protocol editions

ZG23 SoC

The Silicon Labs ZG23 SoC is a single-die solution that comes with a 78 MHz ARM Cortex-M33 with a high-performance sub-GHz radio providing low power, low cost, long-range, and secure wireless SoC solution. The ZG23 wireless SoCs offer ultra-low transmit current (9.8 mA @ 0 dBm) and ultra-low receive current (4.0 mA), resulting in drastically increasing battery life up to 10 years. The SoCs also offer the best-in-class RF output power of up to +20 dBm and RX sensitivity of -110 dBm (100 kbps O-QPSK), allowing the IoT end nodes to achieve a wireless range of over 1.5 miles.

ZG23 wireless SoCs add the highest level of device security with Secure Vault™ and Z-Wave S2. Secure Vault helps protect connected products, data, and intellectual property against evolving security threats. It also provides future proofing for coming security regulations. Secure Vault technology combines best-in-class security software, and hardware technology features like a physically unclonable function (PUF) secure key storage mechanism to significantly reduce the risk of IoT security breaches. Secure Vault Attestation and Secure Boot can be used to ensure the Silicon Labs product in the customer end device is not cloned or tampered with, and that it is running secure code at any point in the lifecycle. ZG23 also supports UL-1023 Certification which is a standard for household burglar-alarm system units.

The Silicon Labs ZGM230S is a small form-factor (6.5mm x 6.5mm) System-in-Package (SiP) module for Z-Wave 800 connectivity and networking. It delivers robust RF performance, long-range, industry-leading security features, low-current consumption, and a rich set of MCU peripherals.
