Renesas Expands RA Family with RA2E1 MCU for Cost-Sensitive, Space-Constrained Applications

Advanced semiconductor solutions supplier Renesas Electronics Corporation has expanded its 32-bit RA2 Series microcontrollers (MCUs) with 48 new RA2E1 Group MCUs. The RA2E1 MCUs, based on 48-MHz Arm® Cortex®-M23 core, are entry-line, single-chip devices with up to 128-KB code flash and 16-KB SRAM memory.

Advanced semiconductor solutions supplier Renesas Electronics Corporation has expanded its 32-bit RA2 Series microcontrollers (MCUs) with 48 new RA2E1 Group MCUs. The RA2E1 MCUs, based on 48-MHz Arm® Cortex®-M23 core, are entry-line, single-chip devices with up to 128-KB code flash and 16-KB SRAM memory.

The RA2E1 Group MCUs support wide operating voltage range of 1.6V to 5.5V and a large selection of packages such as LQFP, QFN, LGA, BGA and Wafer Level Chip Scale Package (WLCSP). They deliver optimized combinations of superior performance, ultra-low-power consumption, innovative peripherals and small package options.

These features make the RA2E1 Group ideal for cost-sensitive applications and other systems requiring high performance and low-energy consumption in space-constrained applications.

The new MCUs offer an upgrade path with hardware and software scalability, so they are the perfect entry point into the wide line-up of the Renesas RA family.

Commenting about the new addition, Roger Wendelken, Senior Vice President of Renesas’ IoT and Infrastructure Business Unit, said “the RA2E1 Group is an important addition to our RA Family.”

“These devices are outstanding for any designer, delivering a wide-range of popular features and options for applications, such as consumer products, appliances and industrial equipment. Additionally, they serve as an entry point into our RA2 Series, offering seamless upgrade to larger RA Family devices with hardware and software scalability,” Wendelken added.

The upgraded low power capability in the RA2E1 MCUs cover all on-chip peripherals, the flash memory and SRAM. This capability allows the smallest possible power consumption over the devices’ entire temperature and voltage range. System design flexibility is maximized across diverse applications via multiple low power modes. When benchmarked for power consumption, the RA2E1 MCU was certified with an EEMBC ULPMark™ score of 321 at 1.8V, verifying its best-in-class power rating. Users can now minimize active power consumption close to standby levels to extend battery life.

The RA2E1 MCUs also offer an IEC60730 self-test library and feature integrated safety functions that provide confirmation of normal operation. Customers can easily use these safety functions to perform MCU self-diagnostics. Meanwhile, the RA2E1 MCUs are available now from Renesas’ worldwide distributors.
