Renesas Expands RA MCU Portfolio with New Line Group

Renesas Electronics has broadened its 32-bit RA Family of microcontrollers (MCUs) family with a new Group based on the latest Arm® Cortex®-M33 core.

RenesasThe new 100-MHz RA4E1 Group has best-in-class power consumption balanced with high performance and optimized feature integration. It enables fast design cycles and easy upgrades to other RA Family devices.

“Our RA Family continues to exceed expectations by delivering market-leading performance, features, ease-of-design and value,” said Roger Wendelken, Senior Vice President in the IoT and Infrastructure Business Unit at Renesas. “The new RA4E1 Group was developed to meet the requests of our customers to extend the already-wide RA product family with an Entry-line option. We’re confident that these parts will hit the sweet spot for a wide range of applications, and that many designers will find that the RA family meets their needs for current and future developments.”

Renesas’ RA Family now boasts over 150 parts ranging from 48MHz to 200MHz.

The RA Family MCUs offer industry-leading power consumption specifications, a very wide range of communications options, and best-in-class security options, including Arm TrustZone® technology.

All RA devices are supported by the Renesas Flexible Software Program (FSP) that includes highly efficient drivers and middleware to ease the implementation of communications and security. The FSP’s GUI simplifies and accelerates the development process.

It enables flexible use of legacy code as well as easy compatibility and scalability with other RA Family devices.

The RA4E1 MCUs are the first Entry-Line Group in the 100-MHz RA4 Series. The group includes four different parts, spanning from 48-pin to 64-pin packages, and from 256kB to 512kB of flash memory along with 128kB of SRAM. The RA4E1 devices offer the lowest active power consumption in their class, using only 60µA / MHz while executing from Flash at 100MHz.

Key Features of RA4E1 Group

  • 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
