Low-Price RA0E2 Units Goal Client Electronics, Small Home equipment, Industrial System Management and Constructing Automation
Renesas Electronics Company, a premier provider of superior semiconductor options, at the moment launched the RA0E2 microcontroller (MCU) Group primarily based on the Arm Cortex -M23 processor. The brand new, cost-competitive units provide extraordinarily low energy consumption, prolonged temperature vary, and all kinds of peripheral capabilities and security options.
Renesas launched the RA0 MCU collection in 2024 and it has shortly turn into very fashionable with a variety of consumers because of its affordability and low energy consumption. RA0E1 units have already been adopted in shopper electronics, equipment and white items, energy instruments, industrial monitoring and different functions.
RA0E2 MCUs are totally appropriate with RA0E1 units, providing pin-expansion whereas sustaining the identical peripherals and ultra-low energy. This compatibility lets prospects re-use current software program property. The brand new units ship industry-leading energy consumption of solely 2.8mA present in energetic mode, and 0.89 mA in sleep mode. As well as, an built-in Excessive-speed On-Chip Oscillator allows the quickest wake-up time for this class of microcontroller. The quick wake-up allows the RA0 MCUs to remain in Software program Standby mode extra of the time, the place energy consumption drops to a minuscule 0.25 µA.
Renesas’ RA0E1 and RA0E2 ultra-low energy MCUs ship a super answer for battery-operated shopper electronics units, small home equipment, industrial system management and constructing automation software.
Function Set Optimized for Low Price
The RA0E2 units have a function set optimized for cost-sensitive functions. They provide a large working voltage vary of 1.6V to five.5V so prospects don’t want a degree shifter/regulator in 5V methods. The RA0 MCUs additionally combine timers, serial communications, analog capabilities, security capabilities and safety performance to cut back buyer BOM value. A variety of packaging choices can also be accessible, together with a tiny 5mm x 5mm 32-lead QFN.
As well as, the brand new MCU’s high-precision (±1.0%) HOCO improves baud fee accuracy and allows designers to forego a standalone oscillator. In contrast to different HOCOs within the {industry}, it maintains this precision in environments from -40°C to 125°C. This vast temperature vary allows prospects to keep away from expensive and time-consuming “trimming,” even after the reflow course of.
“The market reception for our RA0 Sequence has exceeded even our personal excessive expectations,” mentioned Daryl Khoo, Vice President of the Embedded Processing Advertising Division at Renesas. “The RA0E2 Group MCUs ship the identical ultra-low energy and value level which have been so in style with our prospects. The addition of prolonged temperature vary and extra reminiscence opens up much more functions and use circumstances. We plan to additional develop the RA0 product lineup, delivering optimum options for 8-16 bit MCU customers transitioning to 32-bit MCUs.”
Key Options of the RA0E2 Group MCUs

- Safety: Distinctive ID, TRNG, AES libraries, Flash learn safety
- Packages: 32- and 48-lead QFNs, 32-, 48-, and 64-pin LQFP
The brand new RA0E2 Group MCUs are supported by Renesas’ Versatile Software program Bundle (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 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 software improvement. Utilizing the FSP will ease migration of RA0E1 designs to bigger RA0E2 units.
