Decode MCU IC Renesas R5F212CCSNFP

We can decode Renesas R5F212CCSNFP MCU IC, please view the microcontroller chip features for your reference:


The R8C/2C Group and R8C/2D Group of single-chip MCUs incorporates the R8C/Tiny Series CPU core,

employing sophisticated instructions for a high level of efficiency. With 1 Mbyte 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


Power consumption is low, and the supported operating modes allow additional power control. These MCUs also

use an anti-noise configuration to reduce emissions of electromagnetic noise and are designed to withstand EMI.

Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of

system components.

Furthermore, the R8C/2D Group has on-chip data flash (1 KB × 2 blocks).

The difference between the R8C/2C Group and R8C/2D Group is only the presence or absence of data flash. Their

peripheral functions are the same.
