Product details
Overview
R5F5631ECDLC#U0 from Renesas is a 100 MHz 32-bit RX631 Group microcontroller featuring a single-precision IEEE-754 FPU, 165 DMIPS performance, 512 KB on-chip flash memory, 128 KB SRAM, and integrated 12-bit/10-bit A/D converters - designed for industrial control and networked embedded systems requiring deterministic real-time response and functional safety support (IEC60730).
For engineers reviewing the R5F5631ECDLC#U0 datasheet, R5F5631ECDLC#U0 pinout, R5F5631ECDLC#U0 application, or R5F5631ECDLC#U0 equivalent, key selection criteria include its 100 MHz CPU clock with no-wait flash access, Ethernet MAC exclusion (distinguishing it from RX63N), USB 2.0 full-speed host/function capability, CAN v2.0B compliance with 32 mailboxes, and 134 general-purpose I/O pins with 5-V tolerance.
Technical Context
The R5F5631ECDLC#U0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a memory protection unit (MPU), JTAG/FINE debug interfaces, and supports little-endian or big-endian data arrangement.
Its peripheral set excludes Ethernet MAC and SDRAM controller (RX63N features), but includes three CAN modules, up to 13 SCI channels, four I²C interfaces (one FM+), three RSPI units, and a parallel data capture unit (PDC) - all synchronized to independent clock domains (ICLK up to 100 MHz, PCLK up to 50 MHz).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDFC | RX63N variant with identical 176-pin LQFP package, 2 MB flash, 256 KB SRAM, and added Ethernet MAC + SDRAM controller | Suitable where 10/100 Mbps wired networking or external memory expansion is required - not drop-in compatible due to pin function reassignment | Select R5F563NEDDFC only if Ethernet or SDRAM interface is mandatory; verify PCB layout changes for ETH_MDC/MDIO and SDRAM signal routing |
| R5F562T7DDFP | RX62T Group part in 100-pin LQFP; 256 KB flash, 32 KB SRAM, no FPU, no USB, but enhanced motor control timers (MTU3) | Targeted at cost-sensitive inverter drives; lacks USB, Ethernet, and floating-point - requires software math libraries | Choose R5F562T7DDFP for high-volume motor control where FPU and USB are unnecessary; expect higher CPU load for trigonometric operations |
Compared with R5F5631ECDLC#U0, R5F563NEDDFC adds Ethernet and SDRAM support at higher cost and power, while R5F562T7DDFP reduces feature set and memory to lower BOM cost - making R5F5631ECDLC#U0 the balanced choice for USB-connected industrial controllers needing FPU and robust analog I/O.

FAQ
What is the maximum operating frequency and flash access performance of the R5F5631ECDLC#U0?
The R5F5631ECDLC#U0 operates at a maximum system clock frequency of 100 MHz. Its 512 KB on-chip flash memory delivers zero-wait-state access at this speed, enabling deterministic instruction fetch timing critical for hard real-time applications such as motor control and PLC scan cycles. This eliminates pipeline stalls during code execution and supports consistent interrupt latency below 1.2 μs.
Does the R5F5631ECDLC#U0 include an Ethernet MAC interface?
No, the R5F5631ECDLC#U0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC and associated EDMAC peripherals present in the RX63N Group. This distinction is confirmed in Renesas documentation (R01DS0098EJ0180, Section 1.2), where RX631 devices are defined by omission of Ethernet functionality - making R5F5631ECDLC#U0 appropriate for USB- or CAN-based networked systems without 10/100 Mbps requirements.
What debugging interfaces does the R5F5631ECDLC#U0 support?
The R5F5631ECDLC#U0 supports both JTAG and FINE (two-wire) on-chip debugging interfaces. JTAG enables full-featured emulation with the E1/E20 debuggers, while FINE reduces pin count for space-constrained designs. Both interfaces provide non-intrusive breakpoint setting, register inspection, and real-time trace - essential for validating IEC60730 safety routines and timing-critical firmware behavior in the R5F5631ECDLC#U0.
How many CAN modules and mailboxes does the R5F5631ECDLC#U0 support?
The R5F5631ECDLC#U0 integrates three independent CAN modules compliant with ISO 11898-1, each supporting up to 32 configurable mailboxes. This allows concurrent handling of standard (11-bit) and extended (29-bit) frame formats across multiple CAN networks - ideal for industrial automation topologies requiring segregated control, diagnostics, and safety message traffic without CPU polling overhead.
Is the R5F5631ECDLC#U0 suitable for IEC60730 Class B compliance?
Yes, the R5F5631ECDLC#U0 includes dedicated hardware features for IEC60730 Class B: oscillation-stop detection, programmable CRC calculator (with X8/X16 polynomials), independent watchdog timer (IWDT), and self-diagnostic capability for the 10-bit A/D converter. These are documented in R01DS0098EJ0180 and eliminate the need for external safety monitors when properly implemented in firmware - reducing BOM cost and board area.
