Description

The RA4E2 entry-line microcontroller is 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.
