FAQ

What is the maximum operating frequency of the R5F10DGECLFB#56?

The R5F10DGECLFB#56 supports a maximum CPU clock frequency of 32 MHz using an external crystal or resonator. Its internal high-speed oscillator operates up to 20 MHz, and the system clock can be further divided or multiplied via on-chip PLL circuitry. This timing capability enables deterministic execution of real-time control algorithms in automotive and industrial applications where R5F10DGECLFB#56 serves as the primary MCU.

Does the R5F10DGECLFB#56 support AEC-Q100 qualification?

Yes, the R5F10DGECLFB#56 is qualified to AEC-Q100 Grade 2 (−40°C to +105°C ambient temperature range), as confirmed in Renesas' official RL78/D1A product documentation and ordering information. This qualification makes R5F10DGECLFB#56 suitable for under-hood and cabin-mounted automotive ECUs where thermal robustness and long-term reliability are mandatory.

How many CAN channels does the R5F10DGECLFB#56 integrate?

The R5F10DGECLFB#56 integrates two independent CAN 2.0B controllers - CAN0 and CAN1 - each supporting full protocol compliance including identifier masking, message filtering, and error frame generation. This dual-CAN capability allows R5F10DGECLFB#56 to serve as a gateway or multi-bus node without external CAN controllers, reducing bill-of-materials and PCB area.

What is the flash memory endurance specification for R5F10DGECLFB#56?

The R5F10DGECLFB#56 features 128 KB of on-chip flash memory rated for 100,000 write/erase cycles per block, with data retention guaranteed for 20 years at 85°C. This endurance enables robust firmware update mechanisms and EEPROM emulation routines within R5F10DGECLFB#56-based designs without requiring external nonvolatile memory.

Is the R5F10DGECLFB#56 pin-compatible with other RL78/D1A 48-pin variants?

Yes, the R5F10DGECLFB#56 shares identical pin configuration and electrical characteristics with other 48-pin RL78/D1A devices in the R5F10DGx series (e.g., R5F10DGC, R5F10DGD), as defined in Section 1.4.2 of the RL78/D1A Hardware User's Manual. This allows direct substitution within the same package footprint when memory or peripheral requirements align - though firmware compatibility must be verified per device-specific register map and feature set.
