MCHPATMEGA128RFR2
Overview
The ATMEGA128RFR2 is an integrated 8-bit AVR microcontroller combined with a high-performance 2.4 GHz wireless transceiver. It is designed specifically for low-power wireless applications, featuring 128 KB of Flash, 16 KB of RAM, and hardware-assisted power consumption reduction to optimize battery life in sensor networks.
Why Choose This Part
This SoC reduces PCB footprint and system cost by integrating the RF front-end directly with a 16 MIPS AVR core. It offers specialized hardware support for Multiple PAN Address Filtering and features a Deep Sleep mode with current consumption as low as 0.7 microamps to maximize deployment longevity.
Applications
Key Specifications
Getting Started
Developers can use the Microchip Studio IDE and the AVR GCC compiler to write firmware, while the Atmel-ICE or JTAGICE3 provides debugging via the JTAG interface. Hardware evaluation is typically performed using the ATmega256RFR2-XSTK Xplained Pro kit, which shares the same architecture and radio core.
