RL78 8/16-bit microcontrollers (MCUs) greatly improve power efficiency with industry-leading low power consumption at 37.5μA/MHz consumption during normal operation and 0.355μA during clock operation. Built-in features such as a high-precision (±1%) high-speed on-chip oscillator, background operation data flash capable of 1 million rewrites, temperature sensor, and interface ports for multiple power supplies help reduce system costs and size.
