Product details
Overview
R5F64115DFB#U0 from Renesas Electronics is a 32-bit CISC microcontroller in the R32C/111 Group, featuring a 50 MHz CPU core, 384 KB flash + 8 KB data flash, 40 KB RAM, IEEE-754 single-precision FPU, and nine UART channels. It serves as a system controller in industrial metering and office equipment with integrated A/D (10-bit × 26), D/A (8-bit × 2), timers (16-bit × 11), and intelligent I/O for waveform generation and time measurement.
For engineers reviewing the R5F64115DFB#U0 datasheet, R5F64115DFB#U0 pinout, R5F64115DFB#U0 application, or R5F64115DFB#U0 equivalent, this page delivers verified package mapping (100-pin LQFP PLQP0100KB-A), confirmed peripheral integration (UART0–UART8, DMAC × 4, CRC-CCITT), operating conditions (−40°C to +85°C, 3.0–5.5 V), and real-world timing roles in motor control and serial protocol bridging.
Technical Context
The R5F64115DFB#U0 implements the R32C/100 Series CPU core with 108 basic instructions, 20 ns minimum instruction execution time at 50 MHz, 32×32→64-bit multiplier, and multiply-accumulate unit. Its memory architecture supports up to 4 GB address space, with user-accessible 64 MB external bus interface supporting wait-state insertion and 8/16-bit data width selection.
It integrates dual clock domains (VCC1/VCC2), four independent clock sources (main/sub/PLL/on-chip oscillator), and low-power modes (wait/stop). The device includes two dedicated D/A converters, a 10-bit A/D converter with sample-and-hold across 26 channels, and three-phase motor control timer using TA1–TA4 and TB2 with 8-bit programmable dead-time generation.
