Product details
Overview
R5F56316CDFB#V0 from Renesas is a 100 MHz 32-bit RX63N Group microcontroller with integrated Ethernet MAC, single-precision IEEE-754 FPU, 165 DMIPS performance, 2 MB on-chip flash, and 128 KB SRAM. It operates from a 2.7–3.6 V supply, supports -40 to +85°C temperature range, and targets industrial networking and embedded control applications requiring deterministic real-time response and secure connectivity.
For engineers reviewing the R5F56316CDFB#V0 datasheet, R5F56316CDFB#V0 pinout, R5F56316CDFB#V0 application, or R5F56316CDFB#V0 equivalent, key selection criteria include Ethernet MAC support (MII/RMII), USB 2.0 host/function/OTG capability, CAN v2.0B compliance with 32 mailboxes, 21-channel 12-bit A/D converter with sample-and-hold, and AES-128/192/256 encryption via DEU.
Technical Context
The R5F56316CDFB#V0 implements the 32-bit RX CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates a dedicated EDMAC for Ethernet offloading, dual DMA controllers (DMAC + EXDMAC), and a DTC for peripheral-triggered transfers - all synchronized to independent clock domains (ICLK up to 100 MHz, PCLK up to 50 MHz).
Its timing subsystem includes MTU2 and TPU timer units supporting PWM generation, input capture, phase counting, and A/D trigger synchronization; RTC with battery backup and time-capture; and IWDT with dedicated 125-kHz LOCO clock. The MCU supports IEC60730 safety functions including oscillation-stop detection, CRC calculation, and A/D self-diagnostic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NEDDFB | Same package (144-pin LQFP), identical 2 MB flash/128 KB SRAM, but lacks Ethernet MAC and USB OTG functionality | Suitable only for non-networked embedded control where Ethernet/USB host capability is unnecessary | Select when cost reduction is prioritized and connectivity requirements are limited to CAN/SCI only |
| R5F566TEHDFB | RX66T Group part: higher 160 MHz CPU, enhanced motor control timers (MTU3), no Ethernet MAC, different pinout and memory map | Optimized for servo drive and inverter control; not drop-in compatible due to peripheral register differences | Choose for high-performance motor control applications requiring advanced PWM and encoder interfaces, not general-purpose networking |
Compared with R5F56316CDFB#V0, R5F563NEDDFB removes Ethernet and USB OTG to reduce cost and complexity for isolated control nodes, while R5F566TEHDFB shifts focus to motor control with higher clock speed and specialized timers but sacrifices network connectivity - making R5F56316CDFB#V0 uniquely balanced for industrial edge devices needing both real-time control and wired connectivity.
