Renesas Electronics unveils RA Family of 32-bit Arm® Cortex®-M microcontrollers (MCUs) with superior performance and advanced security for intelligent IoT edge applications. The RA family consists of four product series of MCUs, ranging from small mobile devices to larger, high-performance, calculation-intensive embedded system controllers. The RA Family is supported by an open and flexible middleware concept called Flexible Software Package (FSP), based on FreeRTOS. The FSP can be expanded or replaced by any other RTOS or middleware. A common DNA makes these MCUs feature and pin-compatible.
