Product details
Overview
R5F56318SGFC#V0 from Renesas is a 100 MHz 32-bit RX63N Group microcontroller with integrated Ethernet MAC, single-precision IEEE-754 FPU, 165 DMIPS performance, 1.5 MB on-chip flash memory, and 192 KB SRAM. It operates from a 2.7–3.6 V supply, supports -40 to +85°C temperature range (D version), and targets industrial networking, gateway, and real-time control applications requiring deterministic timing and protocol offload.
For engineers reviewing the R5F56318SGFC#V0 datasheet, R5F56318SGFC#V0 pinout, R5F56318SGFC#V0 application, or R5F56318SGFC#V0 equivalent, this MCU delivers verified Ethernet/USB/CAN connectivity, hardware-accelerated AES encryption, 12-bit A/D conversion with sample-and-hold, and full JTAG/FINE debug support - all in a 176-pin LQFP package with 5-V-tolerant I/Os.
Technical Context
The R5F56318SGFC#V0 implements the 32-bit RX CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and MPU-enforced memory protection. It integrates dedicated peripherals including an RMII/MII Ethernet controller with 2 KB TX/RX FIFOs, USB 2.0 host/function/OTG module with 2 KB buffer, and three CAN channels compliant with ISO11898-1.
Its clock system combines external crystal oscillator support (4–16 MHz), internal 50 MHz HOCO and 125 kHz LOCO, and programmable PLL for precise ICLK/PCLK/FCLK/BCLK domain separation. The device includes dual A/D converters (21×12-bit + 8×10-bit), two 10-bit D/A channels, RTC with battery backup, and DEU supporting AES-128/192/256 in ECB/CBC modes.

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 |
|---|---|---|---|
| R5F563NKHDFC | Same 176-pin LQFP package, identical 1.5 MB flash and 192 KB SRAM, but rated for -40 to +85°C (D version) with same Ethernet/USB/CAN feature set | No functional difference; differs only in part number suffix encoding and minor packaging variants | Select R5F563NKHDFC when sourcing from alternate Renesas distribution channels or requiring different tape/reel configuration |
| R5F563NJDDFB | 144-pin LQFP variant with 1.5 MB flash, 256 KB SRAM, and identical peripheral set except reduced I/O count (111 vs. 133 pins) | Lower pin count limits expansion bus and parallel interface capability; suitable for space-constrained designs without external memory | Choose R5F563NJDDFB when board area is constrained and full 176-pin I/O is unnecessary, accepting trade-off in external bus flexibility |
Compared with R5F56318SGFC#V0, R5F563NKHDFC offers identical functionality in the same package footprint, while R5F563NJDDFB reduces pin count and increases SRAM but sacrifices external bus width and I/O availability - making it optimal for compact, memory-rich embedded UIs rather than gateway-class systems.
