Overview

The Renesas RZ/A Flexible Software Package (FSP) is designed to provide easy-to-use, scalable, high-quality software for embedded system designs using RZ/A MPUs. The RZ/A FSP is based on an open software ecosystem of production-ready drivers, supporting FreeRTOS, Azure RTOS or bare-metal programming. It also includes a selection of other middleware stacks, providing great flexibility for migrating code from older systems or developing new applications from scratch. FSP and e² studio IDE can be used free of charge on any Renesas device.
