SI24R1 2.4 GHz RF Wireless SPI Transceiver chip QFN20

Description

Introduction: Si24Ri is a single chip radio transceiver for the world wide 2.4 – 2.5 GHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and Enhanced ShockBurst™ protocol engine. Output power, frequency channels, and protocol setup are easily programmable through a SPI interface. Current consumption is very low, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode. Built-in Power Down and Standby modes makes power saving easily realizable. Key Features: True single chip GFSK transceiver • Complete OSI Link Layer in hardware • Keyless entry • Enhanced ShockBurst™ • Auto ACK & retransmit • Address and CRC computation • On the air data rate 1 or 2Mbps • Digital interface (SPI) speed 0-8 Mbps • 125 RF channel operation • Short switching time enable frequency hopping • Fully RF compatible with nRF24XX • 5V tolerant signal input pads • 20-pin package (QFN20 4x4mm) • Uses ultra low cost +/- 60 ppm crystal • Uses low cost chip inductors and 2-layer PCB • Power supply range: 1.9 to 3.6 V Datasheet
