Product Attributes

Features

• High Performance RF-CMOS 2.4GHz radio transceiver targeted for IEEE 802.15.4, ZigBee, RF4CE, 6LoWPAN, and ISM applications
• Industry leading link budget:
  • Receiver sensitivity -101dBm
  • Programmable TX output power from -17dBm up to +4dBm
• Ultra-low current consumption:
  • DEEP_SLEEP = 0.02μA
  • TRX_OFF = 300μA
  • RX_ON (LISTEN) = 11.8mA
  • Smart Receiving Techniques enable further current reduction in LISTEN mode between 10 to 50% from 11.8mA
  • Desensitation will enable further reduction up to 1mA
• BUSY_TX = 13.8mA (at max. transmit power)
• Support for coin cell operation
• Optimized for low BoM Cost and ease of production:
  • Few external components necessary (crystal, capacitors and antenna)
• Easy to use interface:
  • Registers, frame buffer, and AES accessible through fast SPI
  • Only two microcontroller GPIO lines necessary
  • One interrupt pin from radio transceiver
  • Clock output with prescaler from radio transceiver
• Radio transceiver features:
  • 128-byte FIFO (SRAM) for data buffering
  • Fully integrated, fast settling PLL to support Frequency Hopping
  • Supports 500kHz channel spacing
  • Battery monitor and Fast Wake-Up Time <0.4 msec
• Special IEEE 802.15.4 2011 hardware support:
  • FCS computation and Clear Channel Assessment
  • RSSI measurement, Energy Detection and Link Quality Indication
• MAC hardware accelerator:
  • Automated acknowledgement, CSMA-CA and retransmission
  • Automatic address filtering
  • Automated FCS check
• Extended feature set hardware support:
  • Industrial and extended temperature range: -40°C to +85°C and -40°C to +125°C
