Low-Energy, Streamlined Units Goal Vitality Administration, Residence Home equipment, Constructing Automation and Medical Purposes

Renesas Electronics Company, a premier provider of superior semiconductor options, as we speak launched the RA2A2 microcontroller (MCU) Group based mostly on the Arm Cortex-M23 processor. The brand new, low-power units provide a 24-bit Sigma-Delta analog-to-digital converter (SDADC), and an modern dual-bank code flash and financial institution swap operate that make it simple to implement firmware over-the-air (FOTA) updates for sensible vitality administration, constructing automation, medical units, client electronics and different IoT functions that may profit from firmware updates.

The RA2A2 units provide a number of energy constructions and voltage detection {hardware} to appreciate 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 functions requiring lengthy lifetime administration in excessive circumstances. 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 Optimized for Sensible Vitality Administration

RA2A2 MCUs contribute to the digitalization of typical techniques with key options together with high-level analog sensing, FOTA assist, 8KHz/4KHz hybrid sampling, and AES {hardware} accelerator capabilities. When the end-systems are digitalized, it’s doable to investigate particular person techniques standing seamlessly for additional energy-efficient, streamlining system operation. For instance, subsequent technology sensible electrical energy meters with Non-Intrusive Load Administration (NILM) know-how allow vitality consumption monitoring based mostly on detailed evaluation of the present and voltage of the full load. The adoption of sensible meters with NILM is probably the most cost-effective and scalable resolution for growing vitality effectivity and reducing vitality consumption.

“Renesas has labored intently with our clients to grasp their necessities for next-generation techniques that may assist important vitality 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 resolution that can allow vital vitality financial savings in a big 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 Bundle (FSP). The FSP allows quicker utility improvement 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 advanced 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 utility improvement. Utilizing the FSP will ease migration of RA2A2 designs to bigger RA units if clients want to take action.

Profitable Combos

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

Availability

The RA2A2 Group MCUs can be found now, together with the FSP software program and the RA2A2 Analysis Equipment. Samples and kits might be ordered both on the Renesas web site or by way of distributors. Extra info on the brand new MCUs is obtainable at renesas.com/RA2A2.
