Low pin count, compact, low power general-purpose microcontrollers recommended for small electronic devices and sub-microcontrollers
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.

|High-speed internal oscillator||20 MHz +/- 2 %|
|Low-speed internal oscillator(for WDT)||15 KHz +/- 15 %|
|CMOS I/O||6 (N-ch O.D. output:2)||10 (N-ch O.D. output:4)|
|Timers||16-bit (TAU)||2 channels||4 channels|
|12-bit interval||-||1 channel|
|Watchdog (WDT)||1 channel(no window function)|
|Timer output||2 (PWM output:1)||4(PWM output:3)|
CSI:1 ch/Simple-I2C:1 ch/
CSI:2 ch/Simple-I2C:1 ch/
|I2C bus||-||1 channel|
|8/10-bit resolution A/D converter||4 channels||7 channels|
|Selectable Power On Reset (SPOR)||Provided|
|Power source pins||VDD/VSS(no REGC pin)|
|Safety functions||WDT(no window function),TRAP instruction|
|On-chip debug function||Provided|
|Voltage||2.0* to 5.5 V (Flash memory rewritable voltage 4.5 to 5.5 V)|
|Operating ambient temperature||Ta = -40 to 85 ℃|
* Use this product within the voltage range from 2.25 to 5.5 V because the detection voltage (VSPOR) of the selectable
power-on-reset (SPOR) circuit should also be considered.
