Renesas RA4 Microcontrollers

With the release of new microcontrollers, Renesas Electronics has expanded its RA microcontroller family offering optimal value with balanced low power performance and feature integration. The RA4E1 MCUs are the first Entry-Line Group in the 100-MHz RA4 Series ideal for cost-sensitive applications and other systems requiring an optimal combination of performance and low power consumption.

Based on Arm Cortex-M33 Core, the new devices in the RA family enable fast design cycles and easy upgrades to other RA Family devices. The RA group includes four different parts ranging from 48-pin to 64-pin packages, 256kB to 512kB flash memory, and 128kB SRAM. The RA4E1 devices use only 60µA / MHz while executing from Flash at 100MHz. Innovative peripherals, connectivity options, and system cost-saving features are the added features.

Ranging from 48MHz to 200MHz, there are now 150 parts in the RA family of microcontrollers. These MCUs offer the best power consumption specifications, a wide range of communications options, and best-in-class security options, including Arm TrustZone technology. The devices are supported by the Renesas Flexible Software Program (FSP) that includes highly efficient drivers and middleware for easy implementation of communications and security. 

Key Features of the RA4E1 Group of Microcontrollers

  • 100 MHz Arm Cortex-M33 CPU core

  • Integrated flash memory options from 256KB to 512KB; and 128KB RAM

  • Support for wide temperature range: Ta = -40/85°C

  • Package options from 48- to 64-pin

  • Low power operation: 60µA / MHz in active mode while executing at 100MHz; 81µA / MHz executing the CoreMark algorithm from Flash

  • Integrated USB 2.0 Full-Speed Device, Serial Communication, CAN and QSPI

  • System costs reduction with on-chip high precision (±0.25%) internal oscillator using FLL, abundant GPIO, advanced analog, low-voltage detection, and internal reset function

The RA4E1 MCUs with complementary analog and power offerings create Winning Combinations for a variety of applications like smart IoT air purifiers and smart coffee machines for the RA4E1 MCUs. The new RA4E1 MCUs are available on the company website. Also, the customers can get FPB-RA4E1 fast prototype board with an on-chip debugger priced in the 20 USD range which will help them get started with these new devices for their next development project.
