Overview

Even though the RL78/G1N microcontroller has a small pin-count 20-pin package, it is an 8-bit general-purpose microcontroller equipped with large current output terminals for driving LEDs. It allows direct drive of 8-segment 6-digit high brightness LEDs. It is suitable for small appliances, simple lighting fixtures and LED displays for portable batteries, etc.

RL78/G1N-Block Diagram
  • 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
  • PWM Output: 3
  • 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, Power-on-reset, On-chip debugger interface
