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.
