Overview

The Si4460-C2A-GMR is a high-performance, low-current EZRadioPRO sub-GHz RF transceiver designed by Silicon Labs. It offers a wide operating frequency range and high sensitivity of -126 dBm, making it suitable for long-range wireless links in the license-free ISM bands. The device is optimized for battery-powered applications with a shutdown current of only 0.03 uA and a standby current of 0.05 uA.

Why Choose This Part

The Si4460 excels in power efficiency, drawing only 18mA during +10 dBm transmission and featuring a 0.9 uA sleep mode. Its wide supply voltage range of 1.8V to 3.6V and compact 4x4mm QFN-20 package simplify integration into space-constrained, battery-operated designs. The high sensitivity and +13 dBm maximum output power enable a superior link budget compared to standard low-power transceivers.

Applications

Smart Metering
Ideal for wireless automated meter reading (AMR) in gas, water, and heat meters due to its ultra-low power sleep modes.
Home Security and Automation
Used in wireless door sensors, window contacts, and PIR motion detectors that require reliable sub-GHz penetration through walls.
Industrial Remote Control
Provides robust wireless links for industrial telemetry and remote operation in harsh RF environments.
Agricultural Monitoring
Supports long-range sensor networks for soil moisture and environmental monitoring in large-scale farming.

Getting Started

Developers can begin by using the Silicon Labs Wireless Development Suite (WDS) to generate configuration headers for the SPI interface. For hardware evaluation, the 4460-PCE10D868-EK or similar PicoBoard evaluation kits provide a reference layout and RF matching circuit. Firmare development is typically performed in Simplicity Studio, which includes drivers and example code for the EZRadioPRO family.

Also Consider

SX1276 Semtech - Consider this if LoRa long-range modulation is required instead of the standard FSK/GFSK supported by the Si4460.
Si4463 SiLSilicon Labs - A pin-compatible higher-power alternative offering up to +20 dBm output power for increased range.
