Product details
Overview
R5F56316DDLC#U0 from Renesas is a 100 MHz 32-bit RX63N Group microcontroller with integrated Ethernet MAC, single-precision IEEE-754 FPU, 165 DMIPS performance, 512 KB on-chip flash memory, and 128 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 R5F56316DDLC#U0 datasheet, R5F56316DDLC#U0 pinout, R5F56316DDLC#U0 application, or R5F56316DDLC#U0 equivalent, this MCU delivers verified Ethernet/USB/CAN connectivity, hardware-accelerated AES encryption, 12-bit A/D conversion across 21 channels, and full JTAG/FINE debug support - all in a 176-pin LQFP (PLQP0176KB-A) package with 5-V-tolerant I/O.
Technical Context
The R5F56316DDLC#U0 implements the RXv1 CPU core with 5-stage CISC Harvard pipeline, variable-length instructions, and MPU-enforced memory protection. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent PCLK/ICLK domain separation for precise peripheral timing control at up to 50 MHz.
It features dedicated DMA controllers: 4-channel DMAC, 2-channel EXDMAC, and a single-channel EDMAC for Ethernet packet handling. The peripheral set includes three CAN modules (32 mailboxes each), 13 SCI channels supporting UART/I²C/SPI emulation, four RIIC interfaces (1 Mbps max), and dual 10-bit D/A converters with rail-to-rail output.

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 |
|---|---|---|---|
| R5F563NEDDLC#U0 | Same RX63N family, 2 MB flash, 128 KB SRAM, identical 177-pin TFLGA package (PTLG0177KA-A) | Higher flash capacity suits complex protocol stacks or dual-bank OTA; larger footprint requires PCB redesign | Select when firmware size exceeds 512 KB or when TFLGA thermal/mechanical profile is preferred |
| R5F56306DDLC#U0 | RX631 Group variant: no Ethernet MAC, reduced peripheral count (e.g., 1× CAN, 8× SCI), same 176-pin LQFP | Targeted at cost-sensitive non-networked control; lacks hardware Ethernet acceleration and DEU | Choose for simpler control tasks where Ethernet and AES are unnecessary - lower BOM cost and power |
