New Renesas MCUs with Excessive-Decision Analog and Over-the-Air Replace Assist Assist Buyer Techniques Preserve Power

Low-Energy, Streamlined Units Goal Power Administration, House Home equipment, Constructing Automation and Medical Functions

Renesas Electronics Company, a premier provider of superior semiconductor options, right this moment launched the RA2A2 microcontroller (MCU) Group based mostly on the Arm Cortex-M23 processor. The brand new, low-power gadgets supply a 24-bit Sigma-Delta analog-to-digital converter (SDADC), and an revolutionary 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 supply a number of energy constructions and voltage detection {hardware} to understand energy-efficient, ultra-low energy operation as little as 100 µA/MHz in lively mode and 0.40µA in software program standby mode. An unbiased energy provide real-time clock extends battery life for purposes requiring lengthy lifetime administration in excessive circumstances. The brand new MCUs additionally supply 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 Optimized for Good Power Administration

RA2A2 MCUs contribute to the digitalization of standard methods with key options together with high-level analog sensing, FOTA help, 8KHz/4KHz hybrid sampling, and AES {hardware} accelerator features. When the end-systems are digitalized, it’s potential to research particular person methods standing seamlessly 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 based mostly on detailed evaluation of the present and voltage of the whole load. The adoption of sensible meters with NILM is essentially the most cost-effective and scalable answer for rising power effectivity and reducing power consumption.

“Renesas has labored intently with our clients to know their necessities for next-generation methods that may help essential power conservation targets,” stated Akihiro Kuroda, Vice President 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 offer this answer that can allow important power financial savings in a big selection of methods.”

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 permits sooner software 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 clients to combine their very own legacy code and selection of RTOS with FSP, thus offering full flexibility in software growth. Utilizing the FSP will ease migration of RA2A2 designs to bigger RA gadgets if clients want to take action.

Successful Combos

Renesas has mixed the brand new RA2A2 Group MCUs with quite a few appropriate gadgets from its portfolio to supply a big selection of Successful Combos, together with the 3-Part Good Electrical Meter. Successful Combos are technically vetted system architectures from mutually appropriate gadgets that work collectively seamlessly to carry an optimized, low-risk design for sooner time to market. Renesas presents greater than 400 Successful Combos with a variety of merchandise from the Renesas portfolio to allow clients to hurry up the design course of and produce their merchandise to market extra shortly. They are often discovered at


The RA2A2 Group MCUs can be found now, together with the FSP software program and the RA2A2 Analysis Package. Samples and kits will be ordered both on the Renesas web site or by means of distributors. Extra data on the brand new MCUs is on the market at

Renesas MCU Management

The world chief in MCUs, Renesas ships greater than 3.5 billion models per yr, with roughly 50% of shipments serving the automotive business, and the rest supporting industrial and Web of Issues purposes in addition to information heart and communications infrastructure. Renesas has the broadest portfolio of 8-, 16- and 32-bit gadgets, delivering unmatched high quality and effectivity with distinctive efficiency. As a trusted provider, Renesas has a long time of expertise designing sensible, safe MCUs, backed by a dual-source manufacturing mannequin, the business’s most superior MCU course of know-how and an enormous community of greater than 250 ecosystem companions.
