Product Description

Silicon Labs Si4464-B1B-FM is a highly integrated low IF/ISM wireless RF transceiver designed for sophisticated ISM band and sub-1GHz applications requiring robust and flexible communication capabilities. This device supports multiple modulation schemes including GMSK, 4GFSK, GFSK, and OOK, enabling reliable data transmission at rates up to 1Mbps over a wide frequency spectrum ranging from 119MHz to 1050MHz.

Housed in a compact 20-pin QFN package measuring 4mm length and width and 0.85mm height, it is optimized for surface mount technology in industrial, commercial, and communication module designs. The transceiver operates efficiently within a supply voltage range of 1.8V to 3.6V making it suitable for battery-powered and low power applications.

Additional integrated features include a wake-up timer to optimize power consumption, low-battery detection circuits, and transmit and receive FIFO buffers for seamless data handling. The device complies with RoHS standards and supports SPI interfacing for easy integration into microcontroller systems.

This series supports three operating bands enabling versatile deployment. Its wide temperature operation (-40°C to 85°C) ensures reliability in harsh environments such as industrial automation, smart metering, IoT networks, and remote sensing.

Operates across 119-1050MHz frequency bands ensuring multi-band compatibility. High output power capability of up to +20dBm and receiver sensitivity down to -126dBm enhances communication range. Incorporates industry features like power-on reset and general purpose digital I/Os.

Provides compatibility for IEEE 802.15.4g and wireless M-Bus standards for IoT connectivity. Compact QFN package allows for space-saving designs in embedded systems. Suitable for applications in industrial control, smart grid, home automation, and agriculture monitoring.

The Silicon Labs Si4464-B1B-FM RF transceiver is a robust solution for advanced wireless communications requiring configurable modulation, low power consumption, and high integration.
