Overview
Description
This Group is supported only for customers who have already adopted these products. The RL78/F12, F13, F14, F15 Groups are recommended for new designs.
The R8C/34E Group, R8C/34F Group, R8C/34G Group, and R8C/34H 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/34E Group and R8C/34F Group have a single channel CAN module and are suitable for LAN systems in vehicles and for FA. The R8C/34G Group and the R8C/34H Group do not have CAN modules. The R8C/34E Group and the R8C/34G Group have data flash (1KB × 4 blocks) with the background operation (BGO) function.

(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 ...
