The Silicon Labs ZM5304 Modem is a fully integrated Z-Wave modem module in a small 27mm x 15.2mm x 5.5mm form factor. It is an ideal solution for home control applications such as access control, appliance control, AV control, building automation, energy management, lighting, security, and sensor networks in the “Internet of Things”.

A baseband controller, sub-1 GHz radio transceiver, crystal, decoupling, SAW filter, matching, and the antenna is included to provide a complete Z-Wave solution to an application executing in an external host microcontroller. The ZM5304 Modem is certified with the FCC modular transmitter approval, ready to be used in any product without additional testing and license costs.

The ZM5304 Modem is based on an 8-bit 8051 CPU core, which is optimized to handle the data and link management requirements of a Z-Wave node. The UART0 or USB interface can be used to access the Z-Wave stack available in the on-chip Flash memory, or to easily upgrade the modem firmware.
