AT86RF233 Low Power, 2.4GHz Transceiver for ZigBee, RF4CE, IEEE 802.15.4, 6LoWPAN, and ISM Applications PRELIMINARY DATASHEET 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 = 0.02A TRX OFF = 300A RX ON = 11.8mA (LISTEN) 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) Ultra-low supply voltage (1.8V to 3.6V) with internal regulator 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 < 0.4msec 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: AES 128-bit hardware accelerator Antenna Diversity and RX/TX indication Supported PSDU data rates: 250kb/s, 500kb/s, 1000kb/s and 2000kb/s True Random Number Generation for security application Reduced Power Consumption modes Time and phase measurement support Industrial and extended temperature range: -40C to +85C and -40C to +125C I/O and
