Working Principle
The R8C/3G provides an expanded peripheral set over the R8C/2x series. The CAN controller supports CAN 2.0A/B with flexible message buffers and acceptance filtering. The 12KB RAM accommodates larger buffers and CAN message objects. The 128KB flash supports on-chip debugging and self-programming. Data flash (8KB) simulates EEPROM with fine 1KB erase sectors. Multiple timer channels support complex PWM generation for multi-axis motor control.
Applications
- Automotive CAN nodes
- Motor control
- Industrial automation
