Does the R5F5631BCDFP#V0 include an Ethernet MAC controller?
No, the R5F5631BCDFP#V0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC and associated EDMAC peripheral found in the RX63N Group. This distinction is confirmed in Renesas documentation: "RX63N Group products incorporate an Ethernet controller while RX631 Group products do not." The R5F5631BCDFP#V0 instead emphasizes CAN, USB, and multiple serial interfaces for cost-sensitive industrial networking.
What package type and pin count does the R5F5631BCDFP#V0 use?
The R5F5631BCDFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 14 × 14 mm body size and 0.5-mm pitch. It provides 78 general-purpose I/O pins, 17 of which are 5-V tolerant, along with dedicated power, clock, reset, and debug interface pins - matching the pinout defined in Table 1.2 of the R01DS0098EJ0180 datasheet for RX631 Group 100-pin variants.
How much on-chip flash and RAM does the R5F5631BCDFP#V0 integrate?
The R5F5631BCDFP#V0 integrates 1 MB of on-chip main flash memory and 128 KB of on-chip SRAM, both operating at zero wait states up to 100 MHz. It also includes 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles - sufficient for firmware storage, parameter retention, and field-upgrade capability in the R5F5631BCDFP#V0.
Is the R5F5631BCDFP#V0 suitable for IEC 60730 Class B compliance?
Yes, the R5F5631BCDFP#V0 includes multiple hardware features supporting IEC 60730 Class B compliance: oscillation-stop detection, CRC calculator, independent watchdog timer (IWDT), self-diagnostic A/D converter function, and memory protection unit (MPU). These are explicitly listed under "Useful functions for IEC60730 compliance" in the R01DS0098EJ0180 datasheet - confirming their applicability to the R5F5631BCDFP#V0.
