Does the R5F5631BDDBG#G0 include an Ethernet controller?
No, the R5F5631BDDBG#G0 belongs to the RX631 Group and does not integrate an Ethernet MAC or EDMAC. Ethernet functionality is exclusive to the RX63N Group (e.g., R5F563NBDDBG#G0). The R5F5631BDDBG#G0 retains all other RX63N/RX631 peripherals except Ethernet, making it suitable for applications where wired LAN connectivity is not required.
What package type and pin count does the R5F5631BDDBG#G0 use?
The R5F5631BDDBG#G0 uses the PLBG0176GA-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array with 13 × 13 mm body size and 0.8 mm ball pitch. It provides 133 general-purpose I/O pins, all 5-V tolerant, with configurable pull-up, open-drain, and port output enable functionality - confirmed in Renesas document R01DS0098EJ0180.
How much on-chip memory does the R5F5631BDDBG#G0 have?
The R5F5631BDDBG#G0 integrates 1 MB of on-chip flash memory, 128 KB of SRAM, and 32 KB of reprogrammable data flash. Flash supports background programming/erasing (BGO), and SRAM includes deep software standby backup capability - all accessible at full 100 MHz speed with zero wait states, as specified for the R5F5631BDDBG#G0 in the RX631 Group datasheet.
Is the R5F5631BDDBG#G0 qualified for extended temperature operation?
Yes, the R5F5631BDDBG#G0 is the G-version part, rated for operation from −40°C to +105°C. This extended temperature grade is validated for industrial environments with elevated ambient conditions and is supported by Renesas' qualification testing per JESD22-A108. The "G" suffix in R5F5631BDDBG#G0 explicitly denotes this industrial-grade thermal specification.
