MRF24XA
Low-Power, 2.4 GHz ISM-Band IEEE 802.15.4™ RF
Transceiver with Extended Proprietary Features
Features
• IEEE 802.15.4™-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: -17.5 to 0 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
acknowledgement (ACK) and Frame Check
Sequence (FCS)
• Supports all Clear Channel Assessment (CCA)
modes
• Reports ED, RSSI, LQI, and CFO
• Channel Agility with acknowledgements
• 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
• 25 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, RX Listen
Power-Saving modes
• Memory retention in Deep Sleep (<40 nA typical)
• Automated functions minimize MCU ON-time
