Easy-to-Start automotive microcontrollers (ETS MCU) are designed to withstand the rigorous quality and reliability requirements of automotive applications, but they are also well suited for design in industrial or even consumer applications. Renesas has carefully selected two series of the ETS MCU that are easy to use for development, and the website is now easy to access with all the design resources for each selected device family in one place to help you select and design in your next application, and to get to market as fast as possible.

It’s easy to use, easy to develop and easy to access.

ETS MCU consists of these product categories:
16-bit MCU: RL78/F13-LIN, RL78/F13-CAN, RL78/F14 and RL78/F15
32-bit MCU: RH850/F1K, RH850/F1KM-S1, RH850/F1KM-S4, and RH850/F1KH-D8

The RL78 family uses a Renesas proprietary 16-Bit CPU core. This MCU series especially targets the low-pin-count and low-power-consumption application areas. The RH850 F1Kx family uses a Renesas proprietary 32-bit CPU core. This MCU series especially targets high-functionality applications with many state-of-the-art communication protocols such as CAN, FlexRay and Ethernet as well as offering system support for ASIL B and AUTOSAR MCAL 4.2. There are derivatives available with both single and dual CPU cores from 1x 120MHz up to 2x 240MHz CPU clock speeds.

In reference to our previous blog, we received a lot of positive feedback from our customers and were requested to add additional features and services.

We added quite a few items to our frequently asked questions section, highlighting the most popular ones. There, you can find things like support for ASIL applications with the RL78 or support for the Flash Code and Data libraries for the RH850 devices.

Most interest has been in our hardware items. Here, we have filled our stock with:

  • Selected ETS MCU samples are available free of charge in small quantities, and available for purchase from the website for larger quantities.
  • All promoted RL78/F1x and RH850/F1Kx starter kits – immediate shipment available.
