RL78/G10 microcontrollers realize the industry's lowest level of consumption current (CPU: 46 μA/MHz, standby (STOP): 560 nA). With an on-chip oscillator, A/D converter, comparator, and more, and a 10/16-pin package lineup, they support more compact system size. These low pin count microcontrollers are perfect for small consumer electronics.

Features

  • CPU: RL78 core, Max. 20MHz
  • Voltage: 2V to 5.5V
  • Package: 64-pin HTFQFP, 10-pin LSSOP, 16-pin SSOP
  • Memory: SRAM Max. 0.5KB, Program Flash Max. 4KB
  • Timer: 16-bit Timer (ch) x 4, 8-bit Timer (ch) x 4, Watchdog Timer (ch) x 1, 12-bit Interval Timer x 1 ch
  • PWM: PWM Output x 3
  • Analog function: 10-bit A/D Converter (ch) x 8
  • On-chip Oscillator Freq. (MHz): High-Speed: 20, 10. 5, 2.5 1.25MHz Low-speed: 15kHz
  • Others: Power-On Reset, Low Voltage Detection

Applications

  • Office
  • Home Appliance
  • Healthcare
  • Security
