Overview
R5F6411FDFN 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), 8-bit D/A converter (1-channel), and six UART channels - enabling compact motor control, sensor interface, and multi-protocol communication in 64-pin LQFP packaging.
For engineers reviewing the R5F6411FDFN datasheet, R5F6411FDFN pinout, R5F6411FDFN application, or R5F6411FDFN equivalent, this page delivers verified package mapping (PLQP0064KB-A), confirmed 64-pin LQFP pin functions, real-time peripheral allocation (UART0–UART3, UART5, UART8), and validated alternative options for migration or second-sourcing in industrial automation and metering designs.
Technical Context
The R5F6411FDFN implements the R32C/100 Series CPU core with IEEE-754 single-precision FPU, 32-bit barrel shifter, and multiplier-accumulate unit - delivering deterministic 20 ns minimum instruction execution at 50 MHz. Its memory architecture supports up to 4 GB address space, with user-accessible 64 MB external bus interface featuring wait-state insertion and 3V/5V I/O tolerance.
It integrates dual DMA controllers (DMAC and DMAC II) supporting 45 request sources and three transfer modes (single, repeat, chain), alongside intelligent I/O with 16 input-capture and 19 output-compare units - optimized for precise timing-critical waveform generation and encoder feedback in motor drive applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F6411EDFN | 128 KB flash + 8 KB data flash, same 32 KB RAM, identical 64-pin LQFP package and peripheral set | Suitable where firmware footprint is <128 KB and cost sensitivity outweighs future upgrade headroom | Select when legacy code base fits within 128 KB and long-term maintenance favors minimal flash endurance wear |
| R5F64115DFB | 384 KB flash + 8 KB data flash, 40 KB RAM, 100-pin LQFP (PLQP0100KB-A) - adds 3 more UARTs and 6 extra A/D channels | Required for complex HMI, protocol bridging, or field-upgradable firmware with larger image size | Choose when design needs >256 KB flash, additional serial interfaces, or expanded analog I/O without changing core software architecture |
Compared with R5F6411EDFN, the R5F6411FDFN offers 128 KB more flash for feature-rich firmware while retaining identical RAM, peripherals, and pinout; versus R5F64115DFB, it trades 100-pin footprint and extended I/O for lower PCB cost and simpler layout - ideal for cost-optimized industrial controls where 256 KB flash suffices.

FAQ
What is the maximum operating frequency and supply voltage range for the R5F6411FDFN?
The R5F6411FDFN operates at a maximum CPU frequency of 50 MHz with VCC1 and VCC2 supplied between 3.0 V and 5.5 V (VCC1 ≥ VCC2). This voltage range supports direct interfacing with both 3.3 V and 5 V logic families and ensures robust operation across industrial temperature ranges (−40°C to +85°C).
Does the R5F6411FDFN include an integrated analog-to-digital converter, and what are its specifications?
Yes, the R5F6411FDFN includes a 10-bit successive-approximation A/D converter with 20 input channels (AN0_0–AN0_3, AN_0–AN_7, and additional analog-capable pins). It features integrated sample-and-hold circuitry, supports simultaneous sampling across multiple channels, and is referenced to AVCC/AVSS - enabling accurate sensor measurements in industrial and metering applications.
How many UART interfaces does the R5F6411FDFN support, and which ones are available in the 64-pin package?
The R5F6411FDFN supports six UART channels in its 64-pin LQFP configuration: UART0, UART1, UART2, UART3, UART5, and UART8. Each can be configured for asynchronous/synchronous operation, I²C-bus mode (UART0–UART3/UART5), or special mode 2 - providing flexible multi-protocol connectivity without external transceivers.
What debug and programming interfaces are supported by the R5F6411FDFN?
The R5F6411FDFN supports JTAG-based on-chip debugging via the NSD pin and on-board flash programming through the same interface. It requires no external debugger hardware beyond a standard JTAG adapter, and supports full breakpoint, step-through, and memory inspection capabilities - streamlining firmware development and field updates for the R5F6411FDFN.
Is the R5F6411FDFN pin-compatible with other devices in the R32C/111 Group, and what package options exist?
The R5F6411FDFN uses the 64-pin LQFP package (PLQP0064KB-A) and shares identical pin functions and peripheral mappings with other 64-pin R32C/111 variants like R5F6411EDFN. It is not pin-compatible with 100-pin variants (e.g., R5F64110DFB) due to differing pin counts and signal allocations - board layout must match the specific 64-pin footprint.
