The RL78/G22 microcontroller features the industry's lowest current consumption levels of 37.5µA/MHz during CPU operation and 200nA during STOP, as well as a rich array of capacitive touch channels. The lineup of new-generation RL78 general-purpose microcontrollers is extended by offering a variety of 16-48-pin packages and 32-64 KB of flash memory.
Along 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 and can be a seamless replacement, making it suitable for a wide range of applications from home appliances and consumer electronics to industrial equipment.
