Overview
Description
The Renesas RZ Flexible Software Package (FSP) is an enhanced software package designed to deliver user-friendly, scalable, high-quality software for embedded system designs using the Renesas RZ family of Arm® microprocessors. FSP provides a quick and versatile way to build secure, connected IoT devices using production-ready drivers, FreeRTOS™, Azure® RTOS, and other middleware stacks.
Important Notice
We have released the RZ FSP, which integrates the existing RZ/A FSP, RZ/G FSP, RZ/N FSP, RZ/T FSP, and RZ/V FSP into a single package. By consolidating these packages, the previously different user experiences across product series have been unified, improving development and maintenance efficiency for our customers. The existing RZ/A, G, N, T, and V FSPs will continue to be supported until the end of January 2027; however, new features and bug fixes will only be provided in the successor RZ FSP.
We strongly recommend migrating projects created with the existing RZ/A, G, N, T, and V FSPs to the RZ FSP. For migration instructions, please refer to the migration guide.

Videos & Training
Learn how to migrate projects that use the legacy RZ/A, RZ/G, RZ/N, RZ/T, and RZ/V Flexible Software Packages (FSPs) to the unified RZ FSP v4.x.x. The new RZ FSP provides a single framework that supports multiple RZ device families.
We will walk through the full migration process, including creating a new project, moving source code, updating FSP configuration, and completing build and debug steps. It also introduces example use cases, and the same procedure can be applied when migrating to other supported environments.

Software Installation Instructions

e2 studio Integrated Development Environment
The FSP provides a host of efficiency-enhancing tools for developing projects targeting the Renesas RZ series of MPU devices. The e2 studio Integrated Development Environment provides a familiar development cockpit from which the key steps of project creation, module selection and configuration, code development, code generation, and debugging are all managed. FSP uses a Graphical User Interface (GUI) to simplify the selection, configuration, code generation and code development of high level modules and their associated Application Program Interfaces (APIs) to dramatically accelerate the development process.
e2 studio is equipped with set of options to configure various aspects of your application project. Some of these options include:
BSP Configuration
Configure or change MPU and board-specific parameters from the initial project selection.
Clock Configuration
Configure the MPU clock settings for your project. The Clock Configuration presents a graphical view of the MPU's clock tree, allowing the various clock dividers and sources to be modified.
Pin Configuration
The Pin Configuration provides flexible configuration of the MPU's pins. This configures the electrical characteristics and functions of each port pin. As many pins are able to provide multiple functions, the pin configurator makes it easy to configure the pins on a peripheral basis. The Pin Configuration tool simplifies the configuration of large packages with highly multiplexed pins by highlighting errors and presenting the options for each pin or for each peripheral.
Module Configuration
The Module Configuration provides options to add FSP modules (HAL drivers, Middleware stacks and RTOS) for RTOS and non-RTOS based applications and configure various parameters of the modules. For each module selected, the Properties window provides access to the configuration parameters, interrupt priorities, pin selections etc.
Interrupt Configuration
Interrupt Configuration allows to add new user interrupts or events and set interrupt priorities. This will also allow the user to bypass a peripheral interrupt and have user-defined ISRs for the peripheral interrupts.
Components Configuration
The Components configuration enables the individual modules required by the application to be included or excluded. All modules that are necessary for the modules added to the application are included automatically. You can easily include or exclude additional modules by ticking the box next to the required component.
