FAQ

What is the operating temperature range specified for the R5F36506CDFA#V0?

The R5F36506CDFA#V0 is rated for industrial operation from -40°C to +85°C. This specification is confirmed in Table 1.6 (D-Version Product List) and applies specifically to this part number's PRQP0100JD-B package. The wider lower limit distinguishes it from the N-version (e.g., R5F36506CNFA), which is limited to -20°C.

Does the R5F36506CDFA#V0 include hardware support for HDMI-CEC communication?

Yes, the R5F36506CDFA#V0 integrates dedicated CEC transmit/receive circuitry with arbitration loss detection and automatic ACK output, as documented in Table 1.4 under "CEC Functions (2)" and Figure 1.4 block diagram. It operates at 32 kHz and uses pin P8_5 (NMI/SD/CEC) for bidirectional signaling.

How many analog-to-digital converter channels does the R5F36506CDFA#V0 support, and what is their resolution?

The R5F36506CDFA#V0 supports 26 channels of 10-bit analog-to-digital conversion with sample-and-hold functionality, as stated in Table 1.2 and Table 1.4. Conversion time is 1.72 µs, and inputs are distributed across ports P0, P2, P9, P10, and ANEX pins - enabling simultaneous multi-sensor monitoring in industrial HMI designs.

What package type and pin count does the R5F36506CDFA#V0 use?

The R5F36506CDFA#V0 uses a 100-pin QFP package designated PRQP0100JD-B (previous code: 100P6F-A), as explicitly listed in Table 1.6 and Figure 1.1. This is distinct from the 128-pin LQFP option used by higher-memory variants like R5F3651ECDFC.

Can the R5F36506CDFA#V0 perform three-phase motor control without external components?

Yes, the R5F36506CDFA#V0 includes hardware timer resources (Timer A1/A2/A4 and Timer B2) and an on-chip dead-time timer specifically for three-phase inverter control, as detailed in Table 1.2 and Figure 1.4. This allows generation of complementary PWM signals with programmable dead time - eliminating external gate-drive logic in BLDC/PMSM drives.
