Product details
Overview
R5F64114DFB from Renesas Electronics is a 32-bit CISC microcontroller in the R32C/111 Group, designed for embedded control in industrial and consumer systems. It features a 50 MHz CPU core with IEEE-754 single-precision FPU, 256 KB flash + 8 KB data flash, 40 KB RAM, 9-channel UART (including I²C-bus support), 26-channel 10-bit A/D converter, and three-phase motor control timer - deployed in office equipment, home appliances, and metering applications.
For engineers reviewing the R5F64114DFB datasheet, R5F64114DFB pinout, R5F64114DFB application, or R5F64114DFB equivalent, key selection criteria include its 100-pin LQFP package, -40°C to +85°C operating range, integrated DMAC II with chain transfer capability, on-chip debug support, and compatibility with Renesas' M16C-family toolchain and peripheral libraries.
Technical Context
The R5F64114DFB implements the R32C/100 Series CPU core with 108 basic instructions, 20 ns minimum instruction execution time at 50 MHz, and hardware multiplier/MAC unit. Its memory architecture supports up to 4 GB address space, with user-accessible external bus interface (8/16-bit data width, wait-state insertion, four chip selects) and dual-voltage operation (VCC1 = 3.0–5.5 V, VCC2 = 3.0 V to VCC1).
It integrates dual clock domains: main/sub oscillators, PLL, and on-chip oscillator; low-power modes (wait/stop); and advanced peripherals including DMAC (4 channels, 51 request sources), intelligent I/O (16 input-capture/19 output-compare channels), CRC-CCITT calculator, and X-Y converter. All timers and serial interfaces are fully configurable via register sets without external components.
