The Renesas RA4M1 group of micrcontrollers (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
  • Segment LCD controller
  • 14-bit A/D converter
  • Capacitive touch sensing unit
  • USB 2.0 Full Speed
  • CAN 2.0B
  • SCI (UART, Simple SPI, Simple I2C)
  • SPI/ I2C multimaster interface

Applications

  • HMI with Seg/Com LCD display
  • Security (fire detection, burglar detection, panel control)
  • Industry (door openers, panel control)
  • HVAC (heating, air conditioning, boiler control)
  • Home appliance
  • General purpose
