What are the key features of MRF24J40-I/ML?
- IEEE 802.15.4 compliant 2.4 GHz transceiver with integrated hardware AES-128 security engine for ZigBee and MiWi mesh networks
- SPI interface at up to 10 MHz enables connection to any microcontroller family without dedicated RF bus hardware
- Compact QFN-40 package (6 mm × 6 mm) with integrated receive LNA and transmit PA simplifies RF PCB layout
What is MRF24J40-I/ML used for?
The MRF24J40 is the RF front-end of choice for ZigBee home-automation sensors, wireless building-control nodes, and industrial wireless mesh networks operating in the 2.4 GHz ISM band. Its SPI interface and hardware AES-128 engine allow any 8-bit or 32-bit MCU to implement a fully compliant IEEE 802.15.4 stack with minimal software overhead. Smart metering, agricultural sensor networks, and wireless HVAC controllers leverage its low-power receive mode to achieve multi-year coin-cell battery lifetimes.

Frequently Asked Questions
What wireless standard does the MRF24J40 support, and at what frequency band does it operate?
The MRF24J40 is fully compliant with IEEE 802.15.4-2003 and operates in the 2.4 GHz ISM band across 16 channels with 5 MHz spacing. It supports data rates up to 250 kbps and integrates hardware CSMA-CA and beacon management to reduce host MCU protocol overhead.
How does the integrated AES-128 hardware security engine in the MRF24J40 benefit ZigBee network designs?
The MRF24J40 includes an AES-128 hardware encryption/decryption block that processes a 16-byte block in under 1 µs, offloading security operations from the host MCU and enabling ZigBee AES-CCM* authenticated encryption at full 250 kbps air throughput without increasing CPU load above 10%.
How does the MRF24J40's SPI interface enable multi-vendor MCU integration, and at what clock speed does it operate?
The MRF24J40 uses a standard 4-wire SPI slave interface supporting clock rates up to 10 MHz, making it directly compatible with PIC, AVR, ARM Cortex-M, and MSP430 microcontrollers operating at 3.3 V. No dedicated RF bus or level translation is required for 3.3 V MCU systems.
For a battery-powered ZigBee end-device, what is the MRF24J40 receive current, and how does that affect coin-cell runtime?
The MRF24J40 draws approximately 19 mA in receive mode and less than 2 µA in sleep mode. In a duty-cycled ZigBee end-device that sleeps 99.9% of the time with 10 ms active windows every 10 seconds, average current drops below 25 µA — supporting over 2 years of operation from a CR2450 coin cell rated at 620 mAh.
