Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F5631EDDFB#U0 | LQFP-144 package (PLQP0144KA-A); identical flash/SRAM/peripherals but different pinout and thermal profile | Suitable for through-hole prototyping or PCBs requiring surface-mount compatibility with standard LQFP footprints | Select when board layout prioritizes manual assembly, thermal vias, or legacy LQFP tooling over compact TFLGA footprint. |
| R5F5631EDDLK#V0 | G-version variant rated for -40°C to +105°C; otherwise identical electrical specs and pinout | Required for under-hood automotive or high-ambient industrial enclosures where extended temperature operation is mandated | Choose only if ambient operating temperature exceeds +85°C - no functional benefit at standard industrial temperatures. |
Compared with R5F5631EDDLK#U0, the LQFP-144 alternative offers easier rework and thermal management but larger board area, while the G-version provides extended temperature margin at higher cost and identical functionality - neither is pin-compatible, but both share identical register maps and software binaries.

All memory blocks are accessible via the 4 GB linear address space and protected by the MPU - ensuring robust partitioning for safety-critical firmware and data storage in the R5F5631EDDLK#U0.
Which package type and pin count does the R5F5631EDDLK#U0 use?
The R5F5631EDDLK#U0 uses a 145-pin TFLGA package (PTLG0145KA-A) measuring 7 × 7 mm with 0.5 mm ball pitch. It provides 111 general-purpose I/O pins, 18 of which are 5-V tolerant, along with dedicated power/ground, crystal, reset, and debug interface pins. This package enables high-density PCB layouts while maintaining thermal performance suitable for industrial environments.
What security and safety features does the R5F5631EDDLK#U0 support?
The R5F5631EDDLK#U0 includes AES-128/192/256 encryption/decryption (DEU), CRC calculator with three polynomials, independent watchdog timer (IWDT) with dedicated LOCO clock, oscillation-stop detection, and self-diagnostic A/D functions - all aligned with IEC 60730 Class B requirements.
