For engineers reviewing the R5F5631YDGFB#V0 datasheet, R5F5631YDGFB#V0 pinout, R5F5631YDGFB#V0 application, or R5F5631YDGFB#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0144KA-A (144-pin LQFP), confirmed peripheral set excluding Ethernet MAC, and two validated alternative MCUs with matching flash/RAM capacity and temperature grade.
Technical Context
The R5F5631YDGFB#V0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - delivering 165 DMIPS at 100 MHz. It supports little-endian data arrangement and includes MPU for memory protection.
Its clock system integrates PLL, 50-MHz HOCO, and 125-kHz LOCO oscillators, with independent frequency division for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (up to 50 MHz), and BCLK (up to 50 MHz). The device omits Ethernet MAC and sub-clock oscillator, distinguishing it from RX63N variants.

FAQ
What is the maximum operating frequency of the R5F5631YDGFB#V0?
The R5F5631YDGFB#V0 operates at a maximum system clock frequency of 100 MHz, achieved via its internal PLL locked to an external 4–16 MHz crystal. This enables 165 DMIPS performance and zero-wait-state execution from its 1 MB on-chip flash memory - critical for deterministic real-time response in industrial control loops.
Does the R5F5631YDGFB#V0 include an Ethernet MAC controller?
No, the R5F5631YDGFB#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC and associated EDMAC peripheral present in the RX63N Group. Its communication interfaces include USB 2.0 full-speed device mode, CAN, multiple SCI/UART channels, I²C, and SPI - making it suitable for non-Ethernet-connected edge nodes.
What package type and pin count does the R5F5631YDGFB#V0 use?
The R5F5631YDGFB#V0 uses the PLQP0144KA-A package: a 144-pin LQFP with 20 × 20 mm body size and 0.5 mm pitch. This package supports all I/O functions specified for the RX631 Group in 144-pin configuration, including 111 general-purpose I/O pins with 5-V tolerance on 18 pins.
Is the R5F5631YDGFB#V0 compatible with Renesas' E20 emulator for debugging?
Yes, the R5F5631YDGFB#V0 supports JTAG-based debugging with the Renesas E20 emulator. It also supports the FINE (two-wire) interface for minimal pin-count debug sessions. Both interfaces enable full-featured breakpoints, real-time trace, and register inspection - essential for validating timing-critical firmware on the RX631 platform.
What is the operating temperature range for the R5F5631YDGFB#V0?
The R5F5631YDGFB#V0 is rated for –40°C to +105°C (G version), qualifying it for extended-temperature industrial environments such as enclosed control cabinets or outdoor-mounted sensor enclosures. This exceeds the standard D version (–40°C to +85°C) and aligns with high-reliability requirements in factory automation and energy infrastructure.
