SI4355-B1A-FM

The Silicon Labs SI4355-B1A-FM is a versatile, low-current sub-GHz EZRadio receiver designed for a wide array of applications. It covers major frequency bands and provides plug-and-play simplicity with the flexibility required for diverse designs. Its compact 3x3 mm 20-QFN package and low external component count make it both space-efficient and cost-effective.

Key electrical specifications include a frequency range of 283–960 MHz, a receive sensitivity of -116 dBm, and a maximum data rate of 500 kbps. The device operates from a power supply of 1.8 V to 3.6 V and consumes only 10 mA in active mode and 50 nA in standby, ensuring superior battery life. It supports OOK, (G)FSK modulation.

Designed for ease of integration, the Si4355 receiver includes features like Auto Frequency Control (AFC) and Automatic Gain Control (AGC). It also has packet handling capabilities, including preamble, sync word detection, and CRC. The device is suitable for applications such as remote control, home security, telemetry, garage and gate openers, remote keyless entry, home automation, industrial control, sensor networks, and health monitors.

The Si4355-B1A-FM is a surface-mount device housed in a 20-QFN package. It is designed for ease of use and rapid development, with simplified programming options available through Silicon Laboratories' Wireless Development Suite (WDS).
