The new MCUs incorporate the Renesas Electronics RL78 CPU, which achieves high computing performance and extremely low power consumption. They include 32 to 64 KB of flash memory in 20- to 38-pin packages.
The RL78/I1A family of 16-bit MCUs is distinguished by its high performance and extremely low power consumption, making it particularly suitable for LED lighting ballasts. The RL78/I1A family addresses the needs of diverse lifestyles by offering cost reduction, high color dimming, and color temperature control. The RL78I1A supports lighting communication standards for centralized building and office control.
