FAQ

What is the maximum operating frequency and supply voltage range for the R5F3650NNFB#30?

The R5F3650NNFB#30 operates at up to 32 MHz with a supply voltage range of 2.7 V to 5.5 V on both VCC1 and VCC2. This wide voltage range allows direct interfacing with 3.3 V and 5 V logic families and simplifies power design in mixed-voltage systems. The device maintains full specification compliance across this range, including A/D accuracy and timer resolution.

Does the R5F3650NNFB#30 support HDMI CEC functionality natively?

Yes, the R5F3650NNFB#30 includes dedicated CEC transmit/receive circuitry compliant with HDMI CEC standards, including arbitration loss detection and automatic ACK output. It operates at 32 kHz and requires no external components to implement full CEC protocol handling - confirmed in Section 1.2 and Table 1.4 of the R01DS0031EJ0210 datasheet.

How many analog-to-digital converter channels does the R5F3650NNFB#30 provide, and what is their resolution and speed?

The R5F3650NNFB#30 integrates a 10-bit A/D converter with 26 input channels and a conversion time of 1.72 µs. Channels include dedicated AN0–AN7, ANEX0/ANEX1, ADTRG, and 16 additional analog inputs mapped across P0–P2 ports - all supported by sample-and-hold circuitry per the datasheet's Table 1.4 and Figure 1.4 block diagram.

What package type and pin count does the R5F3650NNFB#30 use, and is it RoHS compliant?

The R5F3650NNFB#30 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch). Renesas confirms RoHS compliance for this part number per its material declaration and packaging specifications in the R01DS0031EJ0210 datasheet revision history and ordering information section.

Can the R5F3650NNFB#30 execute three-phase motor control without external hardware?

Yes, the R5F3650NNFB#30 supports complete three-phase inverter control using integrated peripherals: Timer A1/A2/A4 and Timer B2 coordinate PWM outputs, while the on-chip dead-time timer ensures safe switching transitions. This capability is explicitly documented in Table 1.2 and Figure 1.3 block diagram under "Three-phase motor control timer functions".
