Overview
R5F64112DFB from Renesas Electronics is a 32-bit CISC microcontroller in the R32C/111 Group, designed for embedded control in resource-constrained industrial and consumer systems. It features a 50 MHz CPU core, 512 KB flash + 8 KB data flash, 63 KB RAM, IEEE-754 single-precision FPU, and nine UART channels - enabling complex real-time motor control and multi-protocol communication in home appliances and office equipment.
For engineers reviewing the R5F64112DFB datasheet, R5F64112DFB pinout, R5F64112DFB application, or R5F64112DFB equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C operating range, integrated three-phase motor timer with 8-bit dead-time control, 26-channel 10-bit ADC, and dual 8-bit DACs - all critical for deterministic timing and analog signal conditioning in closed-loop systems.
Technical Context
The R5F64112DFB implements the R32C/100 Series CPU core with 108 basic instructions, 20 ns minimum instruction execution time at 50 MHz, and hardware multiplier/MAC/FPU units for efficient fixed- and floating-point math. Its memory architecture supports up to 4 GB address space, with user-accessible 64 MB external bus interface supporting wait-state insertion and 3V/5V I/O.
