Overview
R5F5631NDDFL#V0 from Renesas is a 100 MHz 32-bit RXv1 CPU-based microcontroller in the RX63N Group, featuring integrated Ethernet MAC (10/100 Mbps), full-speed USB 2.0 host/function/OTG, three CAN channels, 21-channel 12-bit A/D converter, dual 10-bit D/A converters, hardware AES encryption (DEU), and 128 KB on-chip SRAM. It operates from a single 2.7–3.6 V supply and targets industrial networking gateways requiring deterministic real-time control with secure connectivity.
For engineers reviewing the R5F5631NDDFL#V0 datasheet, R5F5631NDDFL#V0 pinout, R5F5631NDDFL#V0 application, or R5F5631NDDFL#V0 equivalent, key selection criteria include Ethernet MAC support, 100 MHz deterministic timing, IEC60730 safety features (CRC, self-diagnostic A/D, oscillation detection), and compatibility with Renesas E20/E1 debug tools - all confirmed for this specific LQFP-176 package variant.
Technical Context
The R5F5631NDDFL#V0 implements the RXv1 core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU delivering 165 DMIPS at 100 MHz. Its memory subsystem includes no-wait-state 100 MHz flash (1.5 MB), 128 KB SRAM, and 32 KB reprogrammable data flash (100,000 erase cycles).
Peripheral integration centers on deterministic real-time I/O: MTU2 and TPU timers support PWM, input capture, and phase counting; Ethernet controller uses MII/RMII with dedicated EDMAC (2 KB TX/RX FIFO); USB 2.0 module includes 2 KB buffer and OTG capability; and DEU enables AES-128/192/256 in ECB/CBC modes with key lengths up to 256 bits.
