ZM5101A-CME3R

Overview

The ZM5101A-CME3R is a fully integrated Z-Wave System-in-Package (SiP) module from Silicon Labs, designed for sub-GHz wireless communication. It operates within the frequency range of 865.2 MHz to 926.3 MHz, supporting multiple regional bands including 868 MHz, 908 MHz, and 921 MHz. The module integrates an 8051 core MCU with 128 kB of program memory and 16 kB of SRAM. Key electrical parameters include a maximum output power of 6 dBm and a receiver sensitivity of -104 dBm to -105 dBm. It supports data rates up to 100 kbps and functions on a supply voltage of 2.3 V to 3.6 V.

Feature Summary

• Integrates a Z-Wave RF transceiver with an 8051 microcontroller in a compact System-in-Package form factor.
• Supports global sub-GHz frequency bands compliant with Z-Wave Long Range and standard protocols.
• Provides high receiver sensitivity and configurable output power for reliable mesh network connectivity.

Applications

• Smart home lighting and switch automation
