MRF24J40 IEEE 802.15.4™ 2.4 GHz RF Transceiver

PublishTime：2021-06-15

●OVERVIEW
■The MRF24J40 is an IEEE 802.15.4™ Standard com-pliant 2.4 GHz RF transceiver. It integrates the PHY and MAC functionality in a single chip solution.Figure 1-1 shows a simplified block diagram of a MRF24J40 wireless node. The MRF24J40 creates alow-cost, low-power, low data rate (250 or 625 kbps) Wireless Personal Area Network (WPAN) device. TheMRF24J40 interfaces to many popular Microchip PIC® microcontrollers via a 4-wire serial SPI interface,interrupt, wake and Reset pins.
■The MRF24J40 provides hardware support for:
▲Energy Detection
▲Carrier Sense
▲Three CCA Modes
▲CSMA-CA Algorithm
▲Automatic Packet Retransmission
▲Automatic Acknowledgment
▲Independent Transmit, Beacon and GTS FIFO Buffers
▲Security Engine supports Encryption and Decryption for MAC Sublayer and Upper Layer
■These features reduce the processing load, allowingthe use of low-cost 8-bit microcontrollers.
■The MRF24J40 is compatible with Microchip's ZigBee®, MiWi™ and MiWi P2P software stacks. Each software stack is available as a free download, includ-ing source code.
Features:
■IEEE 802.15.4™ Standard Compliant RF Transceiver
■Supports ZigBee®, MiWi™, MiWi P2P and Proprietary Wireless Networking Protocols
■Simple, 4-Wire Serial Peripheral Interface (SPI)
■Integrated 20 MHz and 32.768 kHz Crystal Oscillator Circuitry
■Low-Current Consumption:
▲RX mode: 19 mA (typical)
▲TX mode: 23 mA (typical)-Sleep: 2 uA (typical)
■Small, 40-Pin Leadless QFN 6x6 mm2 Package
