Renesas Electronics Corporation announced the expansion of its 32-bit RA2 Series microcontrollers (MCUs) with 48 new RA2E1 Group MCUs. Based on the 48-MHz Arm® Cortex®-M23 core, the RA2E1 MCUs are entry-line, single-chip devices with up to 128-KB code flash and 16-KB SRAM memory. The RA2E1 Group MCUs support a 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. 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.
