RA4M3 32-Bit Microcontroller Group

Renesas Electronics RA4M3 32-Bit Microcontroller Group is a family of MCUs based on the 100MHz Arm® Cortex®-M33 core. The RA4M3 MCUs feature up to 1MB code flash memory with background and SWAP operation, 8KB Data flash memory, and 128KB SRAM with Parity/ECC. These highly-integrated devices also include USB 2.0 Full-Speed, SDHI, Quad SPI, a Capacitive Touch Sensing Unit (CTSU), and advanced analog peripherals. Secure element functionality is provided by an integrated Secure Crypto Engine with cryptography accelerators, key management support, tamper detection, and power analysis resistance in concert with Arm TrustZone®.
