Renesas Electronics Corporation

The RA2E1 group is the RA Family’s entry-level single-chip microcontroller based on the 48MHz Arm®Cortex®-M23 core and up to 128KB code flash and 16KB SRAM memory. The optimized processing and Renesas’ low power process technology make it the industry's most energy-efficient ultra-low power MCU. The RA2E1 group supports a wide operating voltage range of 1.6V to 5.5V and a large selection of packages such as LQFP, QFN, LGA, BGA, and WLCSP. The RA2E1 provides pin and peripheral compatibility with the RA2L1 group and is ideal for battery-operated applications and other systems requiring high performance and low-energy consumption in space-constrained applications.

The Renesas RA4M2 group of 32-bit microcontrollers (MCUs) uses the high-performance Arm®Cortex®-M33 core with TrustZone®. In concert with the secure crypto engine, it offers secure element functionality. The RA4M2 is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA4M2 is suitable for IoT applications requiring vast communication options, future proof security, large embedded RAM, and low active power consumption down to 81µA/MHz running the CoreMark®algorithm from Flash.
