MCHPMRF24J40MA-I/RM
Overview
The MRF24J40MA-I/RM is a surface-mountable IEEE 802.15.4 compliant radio transceiver module with an integrated PCB trace antenna. It operates in the 2.4 GHz frequency band and is designed for low-power wireless networking using Zigbee, MiWi, or other proprietary protocols. The module simplifies RF design by integrating the crystal, internal voltage regulator, and matching circuitry into a single shielded package.
Why Choose This Part
This module is pre-certified for FCC, IC, and ETSI, which significantly reduces the cost and complexity of regulatory testing for the final product. It features a simple 4-wire SPI interface that is compatible with most microcontrollers and includes a low-power sleep mode drawing only 2 uA.
Applications
Key Specifications
Getting Started
Engineers can begin development using the MRF24J40MA-I/RM PICtail Plus Daughter Board (AC163022-1) designed to plug into Microchip Explorer 16/32 development kits. Software development is supported through the Microchip MiWi protocol stack and MPLAB X IDE, providing a structured framework for building 802.15.4 mesh or star networks.
