Renesas Electronics Company launched the RA2A2 microcontroller (MCU) Group primarily based 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 progressive dual-bank code flash and financial institution swap operate that make it straightforward to implement firmware over-the-air (FOTA) updates for sensible power administration, constructing automation, medical units, client electronics and different IoT purposes that may profit from firmware updates.
The RA2A2 units provide a number of energy buildings and voltage detection {hardware} to understand energy-efficient, ultra-low energy operation as little as 100 µA/MHz in energetic 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 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 power administration
RA2A2 MCUs contribute to the digitalisation of standard programs 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 digitalised, it’s doable to analyse particular person programs standing for additional energy-efficient, streamlining system operation. For instance, subsequent technology 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 whole load. The adoption of sensible meters with NILM is probably the most cost-effective and scalable resolution for growing power effectivity and reducing power consumption.
“Renesas has labored carefully with our clients to know their necessities for next-generation programs that may assist essential 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 resolution that may allow important power financial savings in a wide selection of programs.”
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 permits sooner software 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 software improvement. Utilizing the FSP will ease migration of RA2A2 designs to bigger RA units if clients want to take action.
Successful combos
Renesas has mixed the brand new RA2A2 Group MCUs with quite a few suitable units from its portfolio to supply a wide selection of Successful Mixtures, together with the 3-Part Sensible Electrical Meter. Successful Mixtures are technically vetted system architectures from mutually suitable units that work collectively to deliver an optimised, low-risk design for sooner time to market. Renesas gives greater than 400 Successful Mixtures 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 shortly.
Availability
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 means of distributors.
