FAQ
What is the maximum operating frequency of the R5F3651NCNFC#V0?
The R5F3651NCNFC#V0 operates at a maximum frequency of 32 MHz when supplied with VCC1 = VCC2 = 2.7 V to 5.5 V. Its minimum instruction execution time is 31.25 ns under these conditions, enabling deterministic real-time performance for motor control loops and protocol timing-critical tasks like CEC and IR reception.
Does the R5F3651NCNFC#V0 support three-phase motor control natively?
Yes, the R5F3651NCNFC#V0 includes dedicated hardware for three-phase motor control: Timer A1, A2, A4 and Timer B2 are configured for inverter gate drive, and an on-chip dead-time timer ensures safe commutation by inserting precise delays between complementary PWM edges-eliminating external dead-time ICs.
What CEC functionality does the R5F3651NCNFC#V0 provide?
The R5F3651NCNFC#V0 implements full HDMI CEC protocol support: bidirectional transmit/receive, arbitration lost detection, automatic ACK generation, and 32 kHz clock operation. It handles physical layer signaling and message framing per CEC specification without requiring external transceivers or software bit-banging.
How many analog-to-digital converter channels does the R5F3651NCNFC#V0 have?
The R5F3651NCNFC#V0 features a 10-bit A/D converter with 26 input channels, including AN0_0–AN0_7, ANEX0/ANEX1, AN0–AN7, and AN2_0–AN2_7. Conversion time is 1.72 µs, and sample-and-hold capability supports simultaneous sampling of multiple motor current/voltage feedback signals.
What is the data flash endurance specification for the R5F3651NCNFC#V0?
The R5F3651NCNFC#V0 specifies 10,000 program/erase cycles for its data flash memory. This endurance rating applies to the 4 KB × 2 blocks allocated specifically for data storage (distinct from program ROM), making it suitable for applications requiring frequent parameter updates or event logging over extended product lifetimes.
