Overview

The R8C/38E, F, G, and H are limited to customers who have already adopted these products. The RL78/F12, F13, F14, F15 Groups are recommended for new designs.

The R8C/38E Group, R8C/38F Group, R8C/38G Group, and R8C/38H Group of single-chip MCUs incorporate the R8C/Tiny Series 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/38E Group and R8C/38F Group have a single channel CAN module and are suitable for LAN systems in vehicles and for FA. The R8C/38G Group and the R8C/38H Group do not have CAN modules. The R8C/38E Group and the R8C/38G Group have data flash (1KB × 4 blocks) with the background operation (BGO) function.

  1. (R8C) Are there any hardware precautions for accurate A/D conversion?

    In order to perform A/D conversion, it is necessary to fully charge the internal capacitor, but if the impedance of the A/D conversion target is high, the discharge and charge will take time and the conversion value will not be accurate. For correct A/D ...

  2. Do I need to rewrite the boot ROM area using MI6C Flash Starter?

    Rewriting of the boot ROM area is unnecessary. This is because M3A-0806 performs programming using the standard boot program which was programmed into the boot ROM area when it was shipped. (#104963)
