Renesas RA4M1

RA4M1 - 32-bit Microcontrollers with 48MHz Arm Cortex-M4 and LCD Controller and Cap Touch for HMI

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.
