SA-Designer lets you design actual analog front-end circuits employing Smart Analog products (Note1) and then generates the circuit data as C source code.



  1. Renesas Smart Analog MCU and Smart Analog IC.

Release Information

Latest Ver.: V1.03.00
Released: Apr 16, 2014


Details of upgrade (See Tool News)

Operating Environment



Conventionally, it took time to prepare hardware according to the sourcing and component changes of analog front-end circuits to fit the sensor behavior. That will be unnecessary with the Smart Analog and SA-Designer, which enables circuit design done easily, just with mouse operation on your computer.

Also, not only can it import data from the Online Simulator "Renesas VA" (Note1) which can be used for sensor selection, the software can also complete everything from sensor selection, circuit design, to program development since it can liaise with the Integrated Development Environment (IDE) "CS+" (Note2), "e² studio" (Note3) and "IAR Embedded Workbench" (Note4).



  1. Tool for sensor selection. This cloud-based tool gives you immediate access to functions supporting design and simulation of analog circuits combining Smart Analog and more than 1,000 sensor products without access to the actual devices.
  2. Renesas Integrated Development Environment that can smoothly run the repeat of coding, building, and debugging with a simple GUI.
  3. Renesas Eclipse-based integrated development environment. For users who intend to unify environments for global collaborative development or who want to use the Eclipse environment.
  4. IAR Embedded Workbench provided by IAR Systems.



  • Use the GUI to design and customize circuits in the style of a block diagram.
  • Display a list of the generated circuit data (register values, etc.), save it for later, and restore old data.
  • Import of circuit data created in Renesas VA Online simulator.
  • Generate C source files for use in circuit design. (Note1)
  • Register to CS+, e² studio, and IAR Embedded Workbench project, and run build, download, and debugging in the CS+, e² studio, and IAR Embedded Workbench.
  • Include tutorials.
