R5F2M131BNFP Datasheet | Renesas

Overview 1.1 Features The R8C/M13B Group of single-chip microcontrollers (MCUs) incorporates the R8C CPU core, which provides sophisticated instructions for a high level of efficiency. With 1 Mbyte of address space, the CPU core is capable of executing instructions at high speed. In addition, it features a multiplier for high-speed arithmetic 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 on the same chip, including multifunction timer and serial interface, reduces the number of system ponents. The R8C/M13B Group includes data flash (1 KB × 2 blocks). 1.1.1 Applications Home appliances, office equipment, audio equipment, consumer products, etc. R01DS0005EJ0200 Rev.2.00 Mar 19, 2012 Page 1 of 48 R8C/M13B Group 1.
