RL78/G22 General Purpose Microcontroller

Renesas' RL78/G22 microcontroller features low current consumption levels of 37.5 µA/MHz during CPU operation and 200 nA during STOP (maintaining 4 KB of SRAM). Additionally, it offers a rich array of capacitive touch channels. The next-generation RL78 general-purpose microcontroller line is extended with 16- to 48-pin packages and 32 KB to 64 KB of Flash memory.

With a maximum operating frequency of 32 MHz, a wide operating voltage range of 1.6 V to 5.5 V, and enhanced analog and security functions, the SNOOZE mode sequencer significantly reduces power consumption during intermittent operation. A rich development environment is provided for the RL78/G22, including an evaluation board (fast prototyping board) that enables program writing/debugging without additional tools simply by connecting a USB cable and a Smart Configurator that facilitates design using a GUI. It is also compatible with the existing RL78 family. It can be a seamless replacement, making it suitable for a wide range of applications, from home appliances and consumer electronics to industrial equipment.
