SILICON LABS SI4330-B1-FM

Si4330 is a highly integrated, single chip wireless ISM receiver. The Si4330 offers advanced radio features including continuous frequency coverage from 240–960 MHz. The Si4330’s high level of integration offers reduced BOM cost while simplifying the overall system design. The extremely low receive sensitivity (–121 dBm) ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can be used to further extend range and enhance performance.

Additional system features such as an automatic wake-up timer, low battery detector, 64 byte RX FIFO, automatic packet handling, and preamble detection reduce overall current consumption and allow the use of a lower-cost system MCU. An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size.

An easy-to-use calculator is provided to quickly configure the radio settings, simplifying customer's system design and reducing time to market.

The Si4330’s digital receive architecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling or increased flexibility and performance.
