Renesas unveils RA2A2 MCUs for energy-efficient IoT purposes

Renesas unveils RA2A2 MCUs for energy-efficient IoT purposes

Renesas Electronics Company launched the RA2A2 microcontroller (MCU) Group primarily based on the Arm Cortex-M23 processor. The brand new, low-power gadgets provide a 24-bit Sigma-Delta analog-to-digital converter (SDADC), and an progressive dual-bank code flash and financial institution swap perform that make it straightforward to implement firmware over-the-air (FOTA) updates for sensible power administration, constructing automation, medical gadgets, shopper electronics and different IoT purposes that may profit from firmware updates.

The RA2A2 gadgets provide a number of energy buildings and voltage detection {hardware} to grasp energy-efficient, ultra-low energy operation as little as 100 µA/MHz in energetic mode and 0.40µA in software program standby mode. An impartial energy provide real-time clock extends battery life for purposes requiring lengthy lifetime administration in excessive situations. The brand new MCUs additionally provide AES {hardware} acceleration, a high-precision (±1.0%), high-speed on-chip oscillator, a temperature sensor and a large working voltage vary from 1.6V to five.5V.

Function set optimised for sensible power administration

RA2A2 MCUs contribute to the digitalisation of standard techniques with key options together with high-level analog sensing, FOTA assist, 8KHz/4KHz hybrid sampling and AES {hardware} accelerator features. When the end-systems are digitalised, it’s attainable to analyse particular person techniques standing for additional energy-efficient, streamlining system operation. For instance, subsequent era sensible electrical energy meters with Non-Intrusive Load Administration (NILM) know-how allow power consumption monitoring primarily based on detailed evaluation of the present and voltage of the overall load. The adoption of sensible meters with NILM is probably the most cost-effective and scalable answer for growing power effectivity and reducing power consumption.

“Renesas has labored carefully with our prospects to grasp their necessities for next-generation techniques that may assist vital power conservation objectives,” mentioned Akihiro Kuroda, a vp of the embedded processing 2nd division at Renesas. “The RA2A2 Group MCUs are the results of that collaboration coupled with our world-leading technical experience. We’re proud to supply this answer that can allow vital power financial savings in a wide selection of techniques.”

Key options of the RA2A2 group MCUs

  • Core: 48MHz Arm Cortex-M23
  • Reminiscence: 512KB built-in, dual-bank Flash reminiscence and 48KB SRAM
  • Analog Peripherals: 24-bit Sigma Delta ADC with digital filter, 12-bit ADC, and temperature sensor.
  • Packages: 100-, 80- and 64-pin LFQFP

The brand new RA2A2 Group MCUs are supported by Renesas’ Versatile Software program Package deal (FSP). The FSP allows sooner utility growth by offering all of the infrastructure software program wanted, together with a number of RTOS, BSP, peripheral drivers, middleware, connectivity, networking and safety stacks in addition to reference software program to construct complicated AI, motor management and cloud options. It permits prospects to combine their very own legacy code and selection of RTOS with FSP, thus offering full flexibility in utility growth. Utilizing the FSP will ease migration of RA2A2 designs to bigger RA gadgets if prospects want to take action.

Profitable mixtures

Renesas has mixed the brand new RA2A2 Group MCUs with quite a few suitable gadgets from its portfolio to supply a wide selection of Profitable Combos, together with the 3-Part Good Electrical Meter. Profitable Combos are technically vetted system architectures from mutually suitable gadgets that work collectively to convey an optimised, low-risk design for sooner time to market. Renesas affords greater than 400 Profitable Combos with a variety of merchandise from the Renesas portfolio to allow prospects to hurry up the design course of and convey their merchandise to market extra shortly.


The RA2A2 Group MCUs can be found now, together with the FSP software program and the RA2A2 Analysis Package. Samples and kits might be ordered both on the Renesas web site or by distributors.
