Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F563NECDFC | Same RX63N Group, identical 2 MB flash / 128 KB SRAM / LQFP-176 package, but lacks G-version unique ID and operates at same -40°C to +85°C range. | No unique 16-byte ID; otherwise functionally identical - suitable where device authentication is not required. | Select R5F563NECDFC if unique ID is unnecessary and cost optimization is prioritized; pinout and firmware are fully compatible. |
| R5F563NFHDFC | Same package and clock speed, but features 2 MB flash + 256 KB SRAM (vs. 128 KB), no Ethernet MAC, and belongs to RX63N Group - confirmed non-Ethernet variant. | Higher RAM capacity enables larger protocol stacks or RTOS workloads, but lacks Ethernet connectivity - requires external PHY or alternate network interface. | Choose R5F563NFHDFC only when Ethernet is omitted and extra SRAM is essential; not a drop-in replacement due to missing ETHERC module and different peripheral mapping. |
Compared with R5S56310CDFC#V0, R5F563NECDFC offers identical Ethernet-enabled functionality at lower cost without unique ID, while R5F563NFHDFC trades Ethernet for doubled SRAM - making the former a true functional alternative and the latter a trade-off for memory-intensive, non-networked applications.

These values are explicitly listed in Table 1.3 of the R01DS0098EJ0180 datasheet under the RX63N Group product list. The memory configuration supports robust firmware updates, real-time data buffering, and persistent parameter storage - key for R5S56310CDFC#V0 deployments in industrial control systems.
Is the R5S56310CDFC#V0 pin-compatible with other RX63N Group MCUs in the same package?
Yes, the R5S56310CDFC#V0 uses the PLQP0176KB-A 176-pin LQFP package and shares identical pinout with other RX63N Group devices in that footprint, including R5F563NECDFC and R5F563NFHDFC. Pin assignments for power, clocks, Ethernet, USB, and peripheral interfaces are consistent across the group, as verified in the "Comparison of Functions for Different Packages" table (Table 1.2) of R01DS0098EJ0180.
