The R8C/38W, X, Y, and Z are limited to customers who have already adopted these products. The RL78/F12, F13, F14, F15 Groups are recommended for new designs.
The R8C/38W Group, R8C/38X Group, R8C/38Y Group, and R8C/38Z Group of single-chip MCUs incorporate the R8C CPU core, employing sophisticated instructions for a high level of efficiency. With 1Mb of address space, and it is capable of executing instructions at high speed. In addition, the CPU core boasts a multiplier for high-speed operation processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs are designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of system components. The R8C/38W Group and R8C/38X Group have a single channel CAN module and are suitable for LAN systems in vehicles and for FA. The R8C/38Y Group and R8C/38Z Group do not have CAN modules. The R8C/38W Group and R8C/38Y Group have data flash (1KB × 4 blocks) with the background operation (BGO) function.
