Renesas Electronics Company 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 straightforward to implement firmware over-the-air (FOTA) updates for sensible vitality administration, constructing automation, medical units, client electronics and different IoT applications that may profit from firmware updates.
The RA2A2 units 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 lively 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 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.
Characteristic set optimised for sensible vitality administration
RA2A2 MCUs contribute to the digitalisation of standard methods with key options together with high-level analog sensing, FOTA help, 8KHz/4KHz hybrid sampling and AES {hardware} accelerator capabilities. When the end-systems are digitalised, it’s attainable to analyse particular person methods standing for additional energy-efficient, streamlining system operation. For instance, subsequent technology sensible electrical energy meters with Non-Intrusive Load Administration (NILM) expertise allow vitality consumption monitoring based mostly on detailed evaluation of the present and voltage of the entire load. The adoption of sensible meters with NILM is essentially the most cost-effective and scalable resolution for rising vitality effectivity and reducing vitality consumption.
“Renesas has labored intently with our prospects to know their necessities for next-generation methods that may help important vitality conservation objectives,” mentioned Akihiro Kuroda, a vice chairman 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 resolution that can allow important vitality financial savings in a wide 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 allows quicker software improvement by offering all of the infrastructure software program wanted, together with a number of RTOS, BSP, peripheral drivers, middleware, connectivity, networking and security 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 software improvement. Utilizing the FSP will ease migration of RA2A2 designs to bigger RA units if prospects want to take action.
Successful combos
Renesas has mixed the brand new RA2A2 Group MCUs with quite a few appropriate units from its portfolio to supply a wide selection of Successful Mixtures, together with the 3-Section Sensible Electrical Meter. Successful Mixtures are technically vetted system architectures from mutually appropriate units that work collectively to convey an optimised, low-risk design for quicker time to market. Renesas affords greater than 400 Successful Mixtures 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 rapidly.
Availability
The RA2A2 Group MCUs can be found now, together with the FSP software program and the RA2A2 Analysis Package. Samples and kits could be ordered both on the Renesas web site or by way of distributors.
