Description

General part information

R8C/34U Series

The R8C/34U Group is supported only for the customers who have already adopted these products. For new adoption, please consider other products such as RL78/G1C, RL78/L1C Group.

The R8C/34P Group, R8C/34R Group of single-chip MCUs incorporates 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/34P Group has data flash (1KB × 4 blocks) with the background operation (BGO) function.
