Single chip 433/868/915MHz Transceiver
Product Specification
Key Features
Applications
• True single chip GFSK transceiver in a small 32 pin
package (32L QFN 5x5mm)
• ShockBurst™ mode for low power operation
• Power supply range 1.9 to 3.6 V
• Multi channel operation – ETSI/FCC Compatible
• Channel switching time <650µs
• Extremely low cost Bill of Material (BOM)
• No external SAW filter
• Adjustable output power up to 10dBm
• Carrier detect for "listen before transmit" protocols
• Data Ready signal when a valid data packet is
received or transmitted
• Address Match for detection of incoming packet
• Automatic retransmission of data packet
• Automatic CRC and preamble generation
• Low supply current (TX), typical 9mA @ -10dBm out-
put power
• Low supply current (RX), typical 12.5mA
• Wireless data communication
• Alarm and security system
• Home automation
• Remote control
• Surveillance
• Automotive
• Telemetry
• Keyless entry
• Toys
