Hi, can you please suggest which renesas MCU has 4 to 5 I2C channels? Thanks!
There are RL78 options that have up to 4-ch of I2C, G14 and G23 both have 2xIICA plus 2x "simplified" I2C via the SAU peripheral.
Something like RX72M also supports lots (013) of "simplified" I2C via the SCI along with 3x full RIIC peripherals.
