The 16-bit CISC MCUs of the R8C Family feature high ROM code efficiency, superb noise performance, low power consumption, high processing performance for real applications, and so on. With the advantage of abundant on-chip peripherals such as comprehensive timer functions and various serial communication functions, the R8C Family supports a wide range of application fields. Products with built-in modules such as a high-speed on-chip oscillator which negates the necessity of a resonator, a power-on reset circuit for cutting back on external parts, a low voltage detection circuit, or an oscillator stop detector to support system safety, are available, contributing to the development of low cost and safe systems. For shorter development times and reductions in total system costs, Renesas offers low-cost development tools as well as an expanding lineup of products with on-chip flash only. The R8C Family also retains compatibility with the M16C Family, so software resources and development tools can be shared.
