Renesas Introduz Série RA MCU Segura para Industrial IoT e Edge Applications

A Renesas Electronics Corp. introduziu sua família Renesas Advanced (RA) de microcontroladores (MCUs) 32-bit Arm Cortex-M — nova linha engineered para secure IoT endpoint e edge device development. Os RA MCUs combinam industry-leading security, optimized connectivity, rich peripheral IP e user-friendly Flexible Software Package (FSP) que streamlines embedded solution design. Complementando hardware está robust partner ecosystem que supplies compatible software e hardware building blocks.

Target Applications e Organização

Os RA MCUs target wide spectrum de aplicações, de industrial e building automation a metering, healthcare e smart home appliances. A família holds PSA Certified Level 1 status e é organizada em RA2 Series (até 60 MHz), RA4 Series (até 100 MHz), RA6 Series (até 200 MHz) e forthcoming dual-core RA8 Series.

Especificações Iniciais

Os iniciais cinco RA MCU groups abrangem 32 scalable devices que feature Arm Cortex-M4 e Cortex-M23 cores. Pin counts range de 32 a 176 pins, code flash memory spans 256 KB a 2 MB, e SRAM scales de 32 KB a 640 KB. Connectivity options incluem USB, CAN e Ethernet, dando designers flexibilidade para migrate seamlessly within RA family.

Segurança Hardware

Segurança é built into hardware: RA MCUs house Renesas' Secure Crypto Engine IP — certified by NIST CAVP — Arm TrustZone para Armv8-M, e tamper-detection circuitry. Additional capabilities como Renesas' HMI capacitive touch technology enhance user interaction.

Flexible Software Package

Developers podem kick-start projects com FSP, que suporta Amazon FreeRTOS, ThreadX e outros RTOS/middleware stacks. ThreadX RTOS e middleware são slated para release early 2020. A open architecture lets teams reuse legacy code e integrate Renesas e ecosystem examples, accelerating implementation de complex functions como connectivity e security.

Roadmap 2020

Roadmap da Renesas para 2020 expande RA lineup com PSA-Certified e Trusted Firmware-M (TF-M) API-compliant devices, incluindo Cortex-M33 MCUs, low-power Cortex-M23 variants e BLE/IEEE 802.15.4 wireless IoT solutions.

Os primeiros cinco RA MCU groups estão now available através dos distributors da Renesas. Unit prices range de $2,50 a $7,00 para orders de 10.000 pieces. O comprehensive development environment inclui on-chip debugging, IDEs, compilers, support tools, evaluation kits, design files, schematics, PCB layouts e BOMs.
