MRF24XA
Low-Power, 2.4 GHz ISM-Band IEEE 802.15.4⢠RF
Transceiver with Extended Proprietary Features
Features
⢠IEEE 802.15.4â¢-2003 and IEEE 802.15.4-2006
Standard Compliant RF transceiver
⢠Multiple air-data-rates:
- 250 kbps (IEEE 802.15.4)
- 125, 500, 1000, 2000 kbps, co-existence with
standard networks
⢠Configurable TX output power: -19 to 1 dBm
⢠Frame header duration scales with the selected
data rate
⢠On-the-fly, per frame air-data-rate detection
(link-by-link independent air-data-rates)
⢠Inferred destination addressing (to further save on
framing overheads; optional)
Full-Featured MCU Support
⢠Hardware frame parser
⢠Hardware CSMA-CA controller, automatic
Acknowledgment (ACK) and Frame Check
Sequence (FCS)
⢠Supports all Clear Channel Assessment (CCA)
modes
⢠Reports ED, RSSI, LQI, and CFO
⢠Channel Agility with acknowledgments
⢠Two independent 128 byte frame buffers
⢠Streaming mode to maximize throughput
⢠Automatic packet retransmit capability
⢠Hardware Security Engine (AES-128) and
configurable Encryption/Decryption mode
Low-Power
⢠Extreme minimization of radio ON time
- Highest channel-admissible data rate used
- 20%-70% overall reduction through framing
⢠2 Mbps frames can reduce radio ON time by a factor
of 4 to 8 with respect to 250 kbps frames
⢠27.5 mA TX current (typical at 0 dBm)
⢠13.5 mA RX current in RX Listen Power-Saving mode
⢠15.5-16.5 mA RX current in RX Packet Demodulation
mode (data rate and device Configuration dependent)
⢠Deep Sleep, Sleep, Crystal ON, and RX Listen
Power-Saving modes
⢠Memory retention in Deep Sleep mode (<40 nA typi-
cal)
⢠Automated functions minimize MCU ON time
General
⢠Low external component count
⢠Best-in-class battery life preservation
⢠Supply range: 1.5V to 3.6V
⢠Compact 32-pin 5x5 mm2 QFN package
⢠Temperature range: -40oC to +85oC
⢠Certified turnkey-ready solutions available
Applications
⢠IEEE 802.15.4/ZigBee® systems (RF4CE and
MiWiTM network)
⢠Industrial monitoring and control
⢠IEEE 1588 precise timing protocol networks
⢠Automatic meter reading
⢠Home building automation
⢠Low-power wireless sensor networks
⢠Consumer electronics, voice and audio
