Overview
Description
The Renesas RA4M1 group of microcontrollers (MCUs) uses the high-performance Arm® Cortex®-M4 core and offers a segment LCD controller and a capacitive touch sensing unit input for intensive HMI designs. The RA4M1 MCU is built on a highly efficient low power process and is supported by an open and flexible ecosystem concept—the Flexible Software Package (FSP), built on FreeRTOS—and is expandable to use other RTOSes and middleware. The RA4M1 is suitable for applications where a large amount of capacitive touch channels and a segment LCD controller are required.
Features
- 48MHz Arm Cortex-M4

RA4M1: Difference between 2 package code
Hello, I want to use a R7FA4M1AB3CNF for one of my project. But while I creating the footprint for this microcontroller, I see 2 thate the R7FA4M1AB3CNF have 2 package code: PWQN0040KC-A PWQN0040KD-A What is the difference between them ? If the product name is the same, how can ...

RA4M1 Flash Write
I need to write the the data flash on an RA4M1. So I selected the "Flash driver" stack. It gives me the Low Power Flash driver whereas the RA4M2 gives me the High Performance Flash Driver. Is that correct? Then it gives me the following error message: "A stack element ...

RA2A1, RA4M1, RA4W1: Can A/D conversion be performed on other analog input?
No. When temperature sensor output or internal reference voltage is selected, please select single-scan mode, remove all analog inputs from conversion target, and perform A/D conversion.

Using RFP with the EK-RA4M1 Board
RFP will not work with the EK-RA4M1 board, when either E2/E2lite or J-Link is chosen as the connection method. That is because these debuggers when used with RFP are not connecting over the SWD/JTAG, but via the Factory boot serial interface. The debugger is ...
