Product details
Overview
R5F6411FDFN#UA 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, 256 KB flash + 8 KB data flash, 32 KB RAM, 10-bit A/D converter (20-channel), and six UART channels - including I²C-bus support - in a 64-pin LQFP package.
For engineers reviewing the R5F6411FDFN#UA datasheet, R5F6411FDFN#UA pinout, R5F6411FDFN#UA application, or R5F6411FDFN#UA equivalent, key selection criteria include its 64-pin LQFP footprint, -40°C to +85°C operating range, integrated three-phase motor control timer, on-chip FPU for single-precision math, and dual-voltage operation (VCC1 = 3.0–5.5 V, VCC2 = 3.0 V to VCC1).
Technical Context
The R5F6411FDFN#UA implements the R32C/100 Series CPU core with IEEE-754 compatible single-precision floating-point unit, 32-bit × 32-bit multiplier, and multiply-accumulate unit - enabling deterministic real-time math for motor control and sensor processing. Its clock system integrates four independent sources: main crystal oscillator (XIN/XOUT), sub-clock (XCIN/XCOUT), on-chip oscillator, and PLL frequency synthesizer.
It supports external memory expansion up to 64 MB via multiplexed or separate 8-/16-bit bus interface with wait-state insertion, four chip-select outputs, and programmable byte-control logic. The DMAC II peripheral enables chain transfers triggered by any peripheral interrupt, supporting immediate data, calculation result, and chained transfer modes without CPU intervention.
