Entry-Line 100MHz Arm® Cortex®-M33 General Purpose
Microcontroller
The RA4E2 group is the newest entry-line microcontroller in the RA4 series
based on the 100 MHz Arm® Cortex®-M33 core with TrustZone.
RA4E2 MCUs offer high-performance and optimized peripheral functions
along with the smallest package options including space saving 36-pin BGA
and 32-pin QFN packages. These satisfy the needs of both cost-sensitive
and space-constrained applications.
The RA4E2 provides an entry point to the wider RA family due to its well-
balanced performance, advanced peripheral functions, and scalability.

Software Package
The Renesas Flexible Software Package (FSP) is designed to provide easy-to-use,
scalable, high-quality software for embedded system designs using the Renesas RA
family. The FSP is based on an open software ecosystem of production-ready drivers,
supporting Azure® RTOS, FreeRTOS™ or bare-metal programming. It also includes
a selection of other middleware stacks, providing great exibility for migrating code
from older systems or developing new applications from scratch.
Tools and Support
The e² studio IDE provides support with intuitive congurators and intelligent code
generation to make programming and debugging easier and faster.
