Description
The Renesas RA4E1 group of 32-bit microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M33 core with TrustZone®. The RA4E1 is built on a highly efficient 40nm process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP) —and is the perfect entry point into the RA Family of microcontrollers. The RA4E1 is suitable for entry IoT applications requiring value-optimized features and connectivity integration, total system cost reduction, and an optimized mixture of high performance with 100MHz Cortex-M33 core in combination with the lowest active power consumption down to 81µA/MHz running the CoreMark® algorithm from Flash.
