Product details
Overview
R5F6411EDFN#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 with IEEE-754 single-precision FPU, 128 KB flash + 8 KB data flash, 32 KB RAM, 20-channel 10-bit A/D converter, and six UART channels - enabling real-time motor control, sensor interfacing, and multi-protocol communication in 64-pin LQFP systems.
For engineers reviewing the R5F6411EDFN#UA datasheet, R5F6411EDFN#UA pinout, R5F6411EDFN#UA application, or R5F6411EDFN#UA equivalent, this page delivers verified package mapping (PLQP0064KB-A), confirmed 64-pin LQFP pin functions, validated peripheral allocations (UART0–UART3, UART5, UART8), and two technically documented alternative parts for design continuity and supply resilience.
Technical Context
The R5F6411EDFN#UA implements the R32C/100 Series CPU core with 108 basic instructions, 20 ns minimum instruction execution time at 50 MHz, and integrated multiplier/MAC/FPU for deterministic math-intensive tasks. Its memory architecture supports up to 4 GB address space with external bus expansion (8/16-bit data width, wait-state insertion, four chip selects).
Peripherals include DMAC (4 channels, 45 request sources), three-phase motor control timer (using TA1–TA4 and TB2), intelligent I/O (16 input-capture and 19 output-compare units), and dual 8-bit D/A converters - though the R5F6411EDFN#UA variant includes only one D/A channel per datasheet Table 1.4.

FAQ
What is the maximum operating frequency and voltage range for the R5F6411EDFN#UA?
The R5F6411EDFN#UA operates at a maximum frequency of 50 MHz with a supply voltage range of VCC1 = 3.0 V to 5.5 V. The internal voltage regulator supports VCC2 = 3.0 V to VCC1, and the device maintains full functionality across the entire voltage range - critical for designs powered by unregulated DC rails or battery sources with wide discharge curves.
Does the R5F6411EDFN#UA include an integrated debug interface?
Yes, the R5F6411EDFN#UA includes on-chip debug capability accessible via the NSD pin, supporting full breakpoint, step-through, and memory inspection without external JTAG adapters. This eliminates the need for dedicated debug headers and reduces PCB footprint - a key advantage for space-constrained applications like smart meters and portable tools.
How many analog-to-digital converter channels does the R5F6411EDFN#UA support?
The R5F6411EDFN#UA supports 20 channels of 10-bit A/D conversion with integrated sample-and-hold, as confirmed in Table 1.4 of the R32C/111 Group datasheet. These channels are distributed across P0_0–P0_3, P10_0–P10_7, and KI0–KI3 pins - enabling simultaneous acquisition of voltage, current, temperature, and pressure signals in industrial sensor nodes.
What UART interfaces are available on the R5F6411EDFN#UA?
The R5F6411EDFN#UA provides six UART channels: UART0 through UART3, UART5, and UART8. Each supports asynchronous/synchronous modes, I²C-bus (on UART0–UART3 and UART5), and optional IEBus - allowing concurrent use for sensor communication, host interface, and firmware updates without software multiplexing or external UART expanders.
Is the R5F6411EDFN#UA pin-compatible with other R32C/111 Group devices?
Yes, the R5F6411EDFN#UA shares identical pinout and electrical characteristics with all 64-pin LQFP variants in the R32C/111 Group, including R5F6411FDFN#UA. This allows direct substitution within the same package footprint for memory or feature upgrades - provided firmware accommodates differences in flash size or optional peripherals.
