FAQ

What is the operating temperature range for the R5F5671EDDFB#10?

The R5F5671EDDFB#10 is rated for –40°C to +105°C (G-version), validated across the full range for industrial and extended-temperature applications. This specification is confirmed in Table 1.1 of R01DS0373EJ0120 Rev.1.20 and applies specifically to the PLQP0144KA-B package variant. Thermal derating is not required within this envelope, and the on-chip temperature sensor (±1°C accuracy) supports runtime thermal monitoring in the R5F5671EDDFB#10.

Does the R5F5671EDDFB#10 support secure boot and firmware authentication?

Yes, the R5F5671EDDFB#10 supports secure boot via its Trusted Memory (TM) function and Trusted Secure IP (TSIP). The TM feature restricts instruction execution to code stored only in designated protected areas of on-chip flash, while TSIP provides hardware-accelerated AES256 decryption and SHA256 verification for authenticated firmware images. These capabilities are documented in the "Encryption function" and "Useful functions for IEC60730 compliance" sections of the R5F5671EDDFB#10 datasheet.

Can the R5F5671EDDFB#10 execute code directly from external QSPI flash?

No, the R5F5671EDDFB#10 does not support XIP (execute-in-place) from external QSPI flash. Its QSPIX interface is designed for fetching configuration data and non-executable assets; code execution is restricted to on-chip flash memory. The QSPIX supports extended/dual/quad SPI protocols and 8–32-bit address widths, but the R5F5671EDDFB#10's memory map and boot ROM do not permit external code execution - a constraint explicitly stated in Section 1.1 of R01DS0373EJ0120 Rev.1.20.

How many CAN channels does the R5F5671EDDFB#10 integrate, and what is the mailbox count per channel?

The R5F5671EDDFB#10 integrates two independent CAN channels compliant with ISO 11898-1 (standard and extended frames), with 32 message mailboxes allocated per channel. This configuration enables concurrent handling of multiple CAN IDs and prioritized message filtering without CPU overhead. The CAN module supports programmable bit timing, loopback self-test, and error counters - all verified in the "Communication function" section of the R5F5671EDDFB#10 datasheet.

Is the R5F5671EDDFB#10 pin-compatible with other RX671 Group members in the same package?

Yes, the R5F5671EDDFB#10 is pin-compatible with all other RX671 Group MCUs offered in the PLQP0144KA-B (144-pin LFQFP) package, including R5F5670EDDFB#10 and R5F5672EDDFB#10. Pin assignments, power domains, and peripheral signal mappings are identical across this package variant per Table 1.2 ("Comparison of Functions for Different Packages") in R01DS0373EJ0120 Rev.1.20 - enabling drop-in replacement where flash size, SRAM, or peripheral enablement aligns with design needs.
