The Renesas Flexible Software Package (FSP) is an enhanced software package designed to provide easy-to-use, scalable, high-quality software for embedded system designs using the Renesas RA Family of Arm Microcontrollers. With the support of new Arm® TrustZone® and other advanced security features, FSP provides a quick and versatile way to build secure, connected IoT devices using production-ready drivers, FreeRTOS™, and other middleware stacks.
FSP includes best-in-class HAL drivers with high performance and low memory footprint. Middleware stacks with FreeRTOS integration are included to ease the implementation of complex modules like communication and security. The e² studio IDE provides support with intuitive configurators and intelligent code generation to make programming and debugging easier and faster.
FSP uses an open software ecosystem and provides flexibility in using bare-metal programming, included FreeRTOS, your preferred RTOS, legacy code, and third-party ecosystem solutions.
