Overview
Description
The RA8E1 Fast Prototyping Board comes equipped with an R7FA8E1AFDCFB microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in SEGGER J-Link™ emulator circuit so you can write and debug programs without additional tools. In addition, with Arduino® UNO and Pmod™ interfaces included standard and through-hole access to all pins of the microcontroller, and so on, it has high expandability.
Sample software is available to demonstrate the functionality of the RA8E1 MCU and for connecting the RA8E1 Fast Prototyping Board with various wireless or sensor modules.

Applications
Design & Development
Videos & Training
Learn how to use the real‑time clock (RTC) module on the RA8E1 fast prototyping board to track and display the current time. We configure the RTC in the flexible software package (FSP), including selecting the low‑speed on‑chip oscillator (LOCO) as the clock source. The project demonstrates how to set the initial date and time through user input and retrieve the RTC calendar values during runtime. The application continuously reads and displays the current time at regular intervals using the SEGGER RTT Viewer, showcasing how the RTC maintains accurate timekeeping.

Hi, I want use the GPT1 only with GTIOC1A for Capture. GTIOC1B is not used. What must I selcet for the Capture A source in the GTICASR. In the datashhet for GTIOCA is always combined with GTIOCB on selcting. I want GTCCRA input capture enabled on the falling edge. In ...
Feb 3, 2026 - GPIO speed
Hello, I am testing how fast I can toggle an IO pin on the FPB-RA8E1 board, in order to determine whether I can use GPIO to drive an 8-bit parallel LCD screen at an acceptable frame rate.I tested two operation methods: one using register operations, and the ...
