This table provides a comparison of the different product series available within the R8C family. For simplicity purposes, it focuses only on the 2x, 3x, and Lx series. Starting from the top, a key specification to note is the operating voltage range. Many microcontroller suppliers have started shifting to 3V devices. The problem with this is that many systems are still being designed around a 5V operation for various reasons including noise immunity. Using a 3V MCU in a 5V design would then require additional circuitry to scale-down the voltage which increases system complexity, reliability and cost. Renesas recognizes these challenges and therefore has decided to support both the 3V and 5V requirements. R8C/2x devices can operate down to 2.2V while the 3x and Lx offer a wider range reaching down to 1.8V. All three series support a 5V power supply. The second bracketed area on this chart is Data Flash and RAM. Most devices in these series offer Data Flash as an option. In the 3x and Lx, the amount of Data Flash is doubled from the R8C/2x offering. As for RAM, the 3x and Lx devices offer up to 10KB RAM.  This provides greater flexibility for more complex applications. LIN is included in all devices targeted for automotive or industrial control. Larger devices within the 3x include up to 2 channels of LIN and CAN to enable efficient and low-cost mini-gateways in network environments. There are three other areas in which these products differ. For enhanced performance, Renesas included a Data Transfer Controller to the 3x and Lx series. The only products with a built-in LCD controller are under the R8C/Lx (just remember “L” for LCD). Also, as previously discussed, the 2x and 3x devices offer versions with Automotive grade.
