Product details
Overview
R5F5631NDDFM#V0 from Renesas is a 100 MHz 32-bit RX CPU-based microcontroller in the RX631 Group, featuring 1.5 Mbytes of on-chip flash memory, 128 Kbytes of SRAM, 32 Kbytes of data flash, and integrated 12-bit/10-bit A/D converters, 10-bit D/A converters, RTC, and USB 2.0 function controller - designed for industrial HMI, motor control, and networked sensor nodes requiring deterministic real-time performance and low-power operation.
For engineers reviewing the R5F5631NDDFM#V0 datasheet, R5F5631NDDFM#V0 pinout, R5F5631NDDFM#V0 application, or R5F5631NDDFM#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed peripheral count per package, Ethernet exclusion status, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The R5F5631NDDFM#V0 implements the RXv1 CPU core with IEEE-754 single-precision FPU, 165 DMIPS @ 100 MHz, and Harvard architecture with 5-stage pipeline. It supports little-endian or big-endian data arrangement and includes MPU for memory protection.
It integrates dual A/D converters (21×12-bit + 8×10-bit), two 10-bit D/A channels, three CAN modules (ISO 11898-1 compliant), up to 13 SCI interfaces, four I²C buses (one FM+), and full-speed USB 2.0 function-only controller - but excludes Ethernet MAC and sub-clock oscillator, distinguishing it from RX63N variants.

Which package type is used for the R5F5631NDDFM#V0?
The R5F5631NDDFM#V0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 mm × 24 mm body size and 0.5 mm pin pitch. This package is confirmed in Table 1.3 of the R01DS0098EJ0180 datasheet and supports all I/O and thermal requirements for industrial applications. The R5F5631NDDFM#V0's pinout matches other 176-pin RX631 variants, enabling layout reuse across flash-density variants.
Does the R5F5631NDDFM#V0 support IEC 60730 functional safety compliance?
Yes, the R5F5631NDDFM#V0 includes hardware features supporting IEC 60730 Class B compliance: oscillation-stop detection, built-in CRC calculator (with X8/X16 polynomials), independent watchdog timer (IWDT), and self-diagnostic capability for the 10-bit A/D converter.
