Part Number : R5F21257SNFP
Function : SINGLE-CHIP 16-BIT CMOS MCU / R8C/24 Group, R8C/25 Group
Manufacturers : Renesas Electronics
These MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C/Tiny Series CPU core, and are packaged in a 52-pin molded-plastic LQFP or a 64-pin molded-plastic FLGA.
It implements sophisticated instructions for a high level of instruction efficiency. With 1 Mbyte of address space, they are capable of executing instructionsat high speed.
Furthermore, the R8C/25 Group has on-chip data flash (1 KB x 2 blocks). The difference between the R8C/24 Group and R8C/25 Group is only the presence or absence of data flash. Their peripheral functions are the same.
