Scalable MCUs deliver leading-edge security, easy development, excellent balance of power and performance
The competitively priced Family of scalable Renesas RA MCUs are powered by Arm® Cortex®-M33, -M23 and -M4 processor cores. These Platform Security Architecture (PSA) Certified™ MCUs deliver a superior combination of security, optimized power/performance, connectivity, peripheral IP and an easy-to-use Flexible Software Package (FSP) to accelerate the development and delivery of next-generation embedded solutions.
Key advantages:
Leading-edge secure connectivity
The RA Family of MCUs delivers advanced security capabilities that include a Secure Crypto Engine (SCE) IP and an extra layer of embedded hardware security that enables tamper detection and resistance to side-channel attacks. Arm TrustZone provisioning employs a system-wide approach with hardware-enforced isolation built directly into the CPU. All RA MCUs supports standard encryption protocols including AES, RSA, ECC, DSA, TRNG and UID. Connectivity options include BLE, 802.15.4, LoRa, NB-IoT, UWB and Wi-Fi.
Excellent balance of power and performance
The RA Family are based on the powerful and energy efficient Arm® Cortex®-M core processors. The low power RA2 series delivers clock speeds up to 60Mhz while providing advanced low power operations that conserve energy. The RA4 and RA6 series deliver performance gains with balanced energy efficiency.
Ease of development
Simplicity boosts efficiency. The 32-bit Renesas RA MCU Family comes complete with a suite of development tools and capabilities that help accelerate your designs and speeds time to value. The Renesas fast-start development tools are part of the Flexible Software Package (FSP) that features extensive support for open architecture, legacy code and third-party ecosystems that will get your solution up and running in no time.
