RL78 Family

The RL78 Family 16-bit microcontrollers are the convergence of the high CPU performance of the 78K0R and the superb on-chip
functions of the R8C and the 78K, and offer a comprehensive lineup
of 10-128 pin and 1-512 KB products for the 8/16-bit market.

Realizing industry-leading low power consumption at 46 μA/MHz
consumption during normal operation and 0.57 μA/MHz during clock
operation, you can expect greatly improved power efficiency using
RL78 microcontrollers. 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.
