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
- 256kB Flash memory and 32kB SRAM
- 8kB Data Flash to store data as in EEPROM
- Scalable from 40-pin to 100-pin packages

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 ...

RA Family: When Does the Current Offset Processing Occurs?
Current offset process is executed at MCU reset.Adjust the offset current according to the current parasitic capacitance value so that the count value becomes the target reference value.For more information, refer to the Application Note "Capacitive Sensor Microcontrollers CTSU Capacitive Touch Introduction Guide (R30AN0218)".
