Silicon Labs SI4432-V2-FM

240MHz ~ 930MHz20dBm（最大）

Overview

Silicon Laboratories’ Si4432 devices are highly integrated, single chip wireless ISM transceivers. The high-performance EZRadioPRO® family includes a complete line of transmitters, receivers, and transceivers allowing the RF system designer to choose the optimal wireless part for their application.The Si4432’s high level of integration offers reduced BOM cost while simplifying the over all system design. The extremely low receive sensitivity (–121 dBm) coupled with industry leading +20 dBm output power 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.The Si4432 offers advanced radio features including continuous frequency coverage from 240–960MHz in 156Hz or 312Hz steps allowing precise tuning control. Additional system features such as an automatic wake-up timer, low battery detector, 64 byte TX/RX FIFOs, automatic packet handling, and preamble detection reduce overall current consumption and allow the use of lower-cost system MCUs. An integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost and size.The Si4432’s digital receive archit ecture features a high-performance ADC and DSP based modem which performs demodulation, filtering, and packet handling for increased flexibility and performance. The direct digital transmit modulation and automatic PA power ramping ensure precise transmit modulation and reduced spectral spreading ensuring compliance with global regulations including FCC, ETSI, ARIB, and 802.15.4d regulations.An easy-to-use calculator is provided to quickly configure the radio settings, simplifying customer's system design and reducing time to market.Applications:• Remote control• Home security & alarm• Telemetry• Personal data logging• Toy control• Tire pressure monitoring• Wireless PC peripherals• Remote meter reading• Remote keyless entry• Home automation• Industrial control• Sensor networks• Health monitors• Tag readers
