Overview
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.
Features
- 100MHz Arm Cortex-M33 with TrustZone
- 128KB Flash memory and 40KB SRAM
- 4KB Data Flash to store data as in EEPROM
- 1KB Standby SRAM
- Scalable from 32-pin to 64-pin packages
- USB 2.0 Full Speed
- CAN FD, I3C
- HDMI CEC, SSI
- 12-bit A/D Converter
- 12-bit D/A Converter
- General PWM Timer

How to check if RA4E2 interrupt timing is correct or not?
Hi, I want to have GTP0 trough interrupt. FSP5.5.0 seems only allowing it if I also enable the crest (cycle end) interrupt, is this behavior correct? Below is fine with both Underflow and overflow interrupts enabled. However, if I disable the overflow, I can't have the underflow ...
