Hi, can you please suggest which renesas MCU has 4 to 5 I2C channels? Thanks!
The RA devices support I2C protocol with 2 different peripherals: IIC and SCI
(apart from RA0 which has IICA and SAU)
SCI offers fewer features and capabilities than IIC, for example it does not support slave operation. Also the FSP supports these peripherals in a different way.
It is more accurate to say that an RA device has up to 3 IIC channels, but I2C can also be supported by the SCI channels.
