Product details
Overview
R5F56318DDFP#V0 from Renesas is a 100 MHz 32-bit RXv1 CPU-based microcontroller in the RX63N Group, featuring an integrated Ethernet MAC (10/100 Mbps), full-speed USB 2.0 host/function/OTG, 3-channel CAN, 12-bit and 10-bit A/D converters (21 + 8 channels), 2-channel 10-bit D/A, hardware AES encryption (DEU), and 128 KB SRAM. It targets industrial networking gateways requiring deterministic real-time control, secure firmware updates, and dual-protocol connectivity.
For engineers reviewing the R5F56318DDFP#V0 datasheet, R5F56318DDFP#V0 pinout, R5F56318DDFP#V0 application, or R5F56318DDFP#V0 equivalent, key selection criteria include Ethernet MAC support (vs. RX631), 176-pin LQFP package with 133 I/Os, 2 MB flash/128 KB SRAM configuration, -40°C to +85°C operation, and IEC60730-compliant safety features including CRC, IWDT, and self-diagnostic A/D.
Technical Context
The R5F56318DDFP#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 zero-wait-state 100 MHz flash (2 MB), 128 KB SRAM, and 32 KB reprogrammable data flash supporting background operations.
Peripheral integration centers on deterministic real-time I/O: MTU2 and TPU timers provide 16-bit PWM, input capture, and phase counting; the dedicated EDMAC offloads Ethernet DMA; and the DEU enables AES-128/192/256 encryption in ECB/CBC modes without CPU intervention - critical for secure OTA updates in field-deployed devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDFP#V0 | Same RX63N Group, identical 176-pin LQFP package, 2 MB flash, but 256 KB SRAM (vs. 128 KB) | Better suited for applications requiring large real-time buffers (e.g., audio streaming, multi-protocol packet queuing) | Select R5F563NEDDFP#V0 when >128 KB SRAM is needed; otherwise R5F56318DDFP#V0 offers optimal cost/SRAM balance |
| R5F563NECDFP#V0 | Same package and memory (2 MB flash / 128 KB SRAM), but includes sub-clock oscillator for RTC battery backup (R5F56318DDFP#V0 lacks this) | Required for applications needing continuous RTC operation during main power loss (e.g., energy meter timestamping) | Choose R5F563NECDFP#V0 only if battery-backed RTC is mandatory; R5F56318DDFP#V0 omits sub-oscillator to reduce BOM count and cost |
Compared with R5F563NEDDFP#V0 and R5F563NECDFP#V0, the R5F56318DDFP#V0 provides identical Ethernet, USB, CAN, and security features at lower SRAM and without sub-oscillator - making it the most cost-efficient variant for non-battery-backed, high-throughput industrial gateways where 128 KB SRAM suffices.
