Renesas is expanding 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 are able to deliver optimised combinations of performance, ultra-low-power consumption, innovative peripherals and small package options. These devices are intended 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.
