Even though the RL78/G1M microcontroller has a small pin-count 20-pin package, it is an 8-bit general-purpose microcontroller equipped with real-time output terminals for motor drive. It has 120-degree energization control and can drive a BLDC motor. It is suitable for motor control for small home appliances, toys, office automation (OA) equipment, etc.
Features
- CPU: RL78 core, Max. 20MHz
- Voltage: 2.0V to 5.5V
- Package: 20-pin TSSOP
- Memory: SRAM Max. 1KB, Program Flash Max. 8KB
- Timer: 16-bit Timer (ch) x 4, Watchdog Timer (ch) x 1, 12-bit Interval Timer x 1 ch
- Real-time output: 8 ch
- Analog function: 8/10-bit A/D Converter (ch) x 8
- On-chip Oscillator Freq. (MHz): 1.25MHz-20MHz (VDD=2.7V-5.5V), 1.25MHz-5MHz (VDD=2.0V *Note)-5.5V)
*Note: Use with a voltage range of 2.25V to 5.5V because it includes detection voltage (VSPOR) for the selectable power-on-reset (SPOR) circuit. - Others: Clock/buzzer output, On-chip debugger interface
