Based on Arm Cortex-M33 core, the RA4 series delivers optimised combination of 100MHz performance with low active power consumption
Based on the latest Arm Cortex-M33 core, here’s presenting the new 100-MHz RA4E1 group of 32-bit microcontrollers (MCUs) by Renesas Electronics. It has best-in-class power consumption along with high performance and optimised feature integration, enabling fast design cycles and easy upgrades to 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. Delivering an optimised combination of innovative peripherals, connectivity options and low-cost system features, the RA4E1 Group is ideal for cost-sensitive applications and other systems requiring an optimal combination of performance and low power consumption.
Key Features
- 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 analogue, low-voltage detection and internal reset function
With the addition of the RA4E1, 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 that 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. Designers using FSP also have access to the extensive Arm ecosystem, offering a wide range of tools that help speed time-to-market, as well as Renesas’ extensive partner network.
“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 extends 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 has combined the RA4E1 MCUs with complementary analogue and power offerings that work together seamlessly to create Winning Combinations for a variety of applications. Examples of these Winning Combinations include a Smart IoT Air Purifier and a Smart Coffee Machine for the RA4E1 MCUs.
All the new RA4E1 MCUs are available today from Renesas Electronics Corporation. To help engineers get started with the RA4E1 MCUs, the company is also offering the FPB-RA4E1 fast prototype board with an on-chip debugger.
