Renesas RA4M1 Processing
The Renesas RA4M1 integrates a 48MHz Arm Cortex-M4 core with hardware floating-point support. Its 256KB Flash, 32KB SRAM and 8KB EEPROM provide resources for sensor acquisition, embedded automation, robotics and real-time control applications.
Expanded GPIO and Peripheral Interfaces
Nineteen digital I/O connections, including eight additional rear I/O points, support complex embedded designs. Six analog inputs and two I²C, two UART and two SPI interfaces provide flexible connectivity for sensors, displays, actuators and control modules.
Precision Analog and CAN Bus Support
The integrated 14-bit analog-to-digital converter and 12-bit digital-to-analog converter support precise measurement and analog control. The CAN Bus interface enables integration with compatible robotics, automotive-development and industrial communication systems.
Low-Power Battery-Powered Design
Multiple operating modes and deep-sleep current as low as approximately 42.6μA at 3.7V help reduce energy consumption. Onboard lithium-battery charging supports portable controllers, wearable electronics and remote sensor devices.
Arduino Prototyping
Arduino IDE compatibility provides an accessible development environment for education and rapid prototyping. Pre-soldered headers allow immediate connection to breadboards, jumper wires and compatible expansion hardware.
Typical Applications
- Smart-control and automation systems
- Arduino programming and electronics education
- Robotics and motor-control projects
- Wearable and battery-powered electronics
- CAN Bus communication equipment
- Sensor acquisition and analog-control devices
- Compact embedded product prototypes
