For engineers reviewing the R5F5631GDGFP#V0 datasheet, R5F5631GDGFP#V0 pinout, R5F5631GDGFP#V0 application, or R5F5631GDGFP#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0100KB-A (100-pin LQFP), confirmed peripheral set excluding Ethernet, USB host/function, and SDRAM controller, and two validated alternative parts with documented functional and packaging differences.

Technical Context

The R5F5631GDGFP#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, 125-kHz LOCO, and 50-MHz HOCO oscillators, with independent frequency division for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (up to 50 MHz), and BCLK (not used, as external bus is disabled in RX631 Group). The device omits Ethernet MAC, USB host/function, and SDRAM controller present in RX63N variants.

FAQ

What is the maximum operating frequency of the R5F5631GDGFP#V0?

The R5F5631GDGFP#V0 operates at a maximum system clock frequency of 100 MHz. This is achieved using the on-chip PLL with an external 4–16 MHz crystal oscillator. At this speed, the RXv1 core delivers 165 DMIPS, supporting deterministic real-time execution for industrial control loops and high-speed data acquisition. The 100 MHz rating applies to ICLK; peripheral clocks (PCLK, FCLK) are independently configurable up to 50 MHz.

Does the R5F5631GDGFP#V0 include an Ethernet MAC controller?

No, the R5F5631GDGFP#V0 does not include an Ethernet MAC controller. It belongs to the RX631 Group, which explicitly excludes Ethernet, USB host/function, and SDRAM controller modules present in the RX63N Group. This distinction is confirmed in the Renesas documentation (R01DS0098EJ0180, Section 1.2, Table 1.2), where Ethernet controller availability is marked "Not available" for all RX631 packages including the 100-pin LQFP variant.

What package type and pin count does the R5F5631GDGFP#V0 use?

The R5F5631GDGFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 14 × 14 mm body size and 0.5-mm lead pitch. This package is RoHS-compliant and includes an exposed thermal pad. Pin compatibility is confirmed across all RX631 100-pin variants, including R5F5631EDGFP#V0 and R5F5630ADGFP#V0, enabling drop-in replacement within the same group for non-G-grade or lower-feature variants.

How much on-chip flash and SRAM does the R5F5631GDGFP#V0 provide?

The R5F5631GDGFP#V0 integrates 512 KB of on-chip main flash memory and 64 KB of on-chip SRAM - both accessible at full speed with zero wait states at 100 MHz. Additionally, it includes 32 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), used for parameter storage and firmware updates. These memory capacities are fixed for this specific part number and match the "512 Kbytes" ROM and "64 Kbytes" RAM entries in Table 1.3 of the official datasheet.

Is the R5F5631GDGFP#V0 qualified for extended temperature operation?

Yes, the R5F5631GDGFP#V0 is the G-version part, qualified for operation from -40°C to +105°C ambient temperature. This extended range is explicitly stated in Table 1.3 of the datasheet (R01DS0098EJ0180) and distinguishes it from the D-version (e.g., R5F5631EDGFP#V0), which is rated only to +85°C. The G-grade qualification makes R5F5631GDGFP#V0 suitable for deployment in high-temperature industrial enclosures and automotive under-hood proximity applications.
