FAQ

What is the maximum operating frequency and supply voltage range for the R5F3650EDFB#V2?

The R5F3650EDFB#V2 operates at up to 32 MHz with a supply voltage range of 2.7 V to 5.5 V on both VCC1 and VCC2. Minimum instruction execution time is 31.25 ns under these conditions, and the device maintains full functionality across its rated -40°C to +85°C temperature range. The dual-supply architecture allows VCC2 to interface with external 3 V or 5 V buses independently of VCC1.

Does the R5F3650EDFB#V2 support HDMI CEC functionality, and how is it implemented?

Yes, the R5F3650EDFB#V2 includes dedicated CEC circuitry compliant with the HDMI CEC standard. It features CEC transmit/receive capability, arbitration lost detection, and automatic ACK output, all operating at 32 kHz. Pin P8_5 serves as the bidirectional CEC I/O, eliminating the need for an external CEC transceiver in AV receiver and set-top box designs.

What are the A/D and D/A converter specifications of the R5F3650EDFB#V2?

The R5F3650EDFB#V2 integrates a 10-bit A/D converter with 26 input channels and sample-and-hold function, achieving a conversion time of 1.72 µs. It also includes two independent 8-bit D/A converters. Analog supplies AVCC and AVSS are separate from digital VCC1/VSS to minimize noise coupling, and the A/D supports simultaneous sampling across multiple channels for motor current sensing.

Which package type and pin count does the R5F3650EDFB#V2 use?

The R5F3650EDFB#V2 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code: 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm lead pitch. This package supports the full peripheral set including 111 I/O ports (85 CMOS, 3 open-drain), external bus interface, and all analog functions - verified in Renesas datasheet R01DS0031EJ0210.

How does the R5F3650EDFB#V2 support three-phase motor control?

The R5F3650EDFB#V2 supports three-phase motor control via integrated timer resources: Timer A1, A2, A4, and Timer B2 are configured for inverter gate drive, with on-chip dead-time insertion to prevent shoot-through. PWM outputs (P9_3/P9_4) and complementary timer inputs enable space-vector modulation, and the 32 MHz core ensures precise timing for ≤1 µs loop jitter in field-oriented control algorithms.
