RF Performance
• High sensitivity
o -116 dBm at 0.6 kBaud, 433 MHz, 1% packet error rate
o -112 dBm at 1.2 kBaud, 868 MHz, 1% packet error rate
• Low current consumption (14.7 mA in RX, 1.2 kBaud, 868 MHz)
• Programmable output power up to +12 dBm for all supported frequencies
• Excellent receiver selectivity and blocking performance
• Programmable data rate from 0.6 to 600 kbps
• Frequency bands: 300-348 MHz, 387-464 MHz and 779-928 MHz

Low-Power Features
• 200 nA sleep mode current consumption
• Fast startup time; 240 µs from sleep to RX or TX mode (measured on EM reference design[2] and[3])
• Wake-on-radio functionality for automatic low-power RX polling
• Separate 64-byte RX and TX data FIFOs (enables burst mode data transmission)

General
• Few external components; Completely on-chip frequency synthesizer, no external filters or RF switch needed
• Green package: RoHS compliant and no antimony or bromine
• Small size (QLP 4x4 mm package, 20 pins)
• Suited for systems targeting compliance with EN 300 220 (Europe) and FCC CFR
Part 15 (US)
• Suited for systems targeting compliance with the Wireless MBUS standard EN 13757-4:2005
• Support for asynchronous and synchronous serial receive/transmit mode for backwards compatibility with existing radio communication protocols
