Renesas Electronics RL78/G23 Low-Power MCUs
Renesas Electronics RL78/G23 Low-Power MCUs feature 44μA/MHz CPU operation and have low power consumption with 210nA at stop 4KB SRAM retention. The MCUs have a snooze mode sequencer that significantly reduces power consumption during intermittent operation. The RL78/G23 group features a wide operating voltage range of 1.6V to 5.5V at up to 32MHz. They also feature a broad range of package pin counts from 30 pins to 128 pins and up to 768KB of flash memory. In addition to enhanced analog and security features, it also incorporates logic and event link controllers (ELCL) and the first capacitive touch sensing unit (CTSU2L) in the RL78 family. A rich development environment is also provided for the RL78/G23, including a fast prototyping board. This board allows for writing and debugging programs with an easy-to-use GUI, by simply connecting a USB cable and a smart configurator without any additional tools required. The RL78/G23 is 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.Features
