Finally, this module will cover the 64- and 80-pin options within the non-LCD line-up. In this area, the R8C/2x and 3x devices offer 128KB options. However, the key difference is RAM size, especially at the higher end of the scale. Many times, these larger devices end up being used as single-chip controllers in a system due to their high functionality and pin count. For this type of application, designers typically require a large amount of RAM for things like communication, data manipulation or simple operating systems. The additional RAM in the 36x or 38x provides great flexibility to meet or even exceed these requirements. Differences to note in these groups include: CAN, LIN, A/D inputs, and an automotive offering.
