FAQ

What is the maximum operating frequency and supply voltage range for the R5F36506CNFB#V0?

The R5F36506CNFB#V0 operates at up to 32 MHz with a supply voltage range of 2.7 V to 5.5 V on both VCC1 and VCC2 pins. At 32 MHz and 2.7–5.5 V, it achieves a minimum instruction execution time of 31.25 ns. The dual-supply architecture allows VCC2 to interface with external 3 V or 5 V buses independently of VCC1.

Does the R5F36506CNFB#V0 support HDMI-CEC functionality, and how is it implemented?

Yes, the R5F36506CNFB#V0 includes two dedicated CEC transceiver circuits compliant with HDMI CEC standards. Pin P8_5 serves as the bidirectional CEC I/O, supporting transmit/receive, arbitration loss detection, and automatic ACK output at 32 kHz. This enables direct integration into HDMI-connected devices without external CEC PHY components.

How many analog-to-digital converter channels does the R5F36506CNFB#V0 provide, and what is their resolution and speed?

The R5F36506CNFB#V0 features a 10-bit A/D converter with 26 input channels, including sample-and-hold capability. Conversion time is 1.72 µs per channel. Inputs are distributed across ports P0 (AN0_0–AN0_7), P10 (AN0–AN7), P2 (AN2_0–AN2_7), and P9 (ANEX0/ANEX1), supporting flexible sensor interfacing in mixed-signal applications.

What package type and pin count does the R5F36506CNFB#V0 use, and is it RoHS compliant?

The R5F36506CNFB#V0 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch). Per Renesas documentation, this package is lead-free and RoHS compliant. It replaces the older 100P6Q-A code and supports standard reflow soldering profiles for surface-mount assembly.

Can the R5F36506CNFB#V0 perform three-phase motor control, and which peripherals enable this function?

Yes, the R5F36506CNFB#V0 supports three-phase inverter control using Timer A1, A2, A4, and Timer B2 in coordinated mode, along with an on-chip dead-time timer. These peripherals generate complementary PWM outputs with programmable dead time, eliminating external logic. The 10-bit A/D converter monitors phase currents, enabling closed-loop field-oriented control in compact motor drive designs.
