Renesas RL78/G23

The Renesas RL78/G23 is the new generation of RL78 family MCUs which achieves further low power consumption than the conventional RL78 MCUs with maintaining compatibility to them. It has several advanced new functions to meet the needs of the market, such as Snooze Mode Sequencer (SMS), Logic & Event Link Controller (ELCL), and Capacitive Touch Sensor. Also enhanced security functions are installed, such as True Random Number Generator (TRNG), Unique ID, and Customer ID. It must be suitable for various IoT endpoint applications.
