Yes, the R5F3650KCNFB#V2 includes dedicated CEC transmit/receive circuitry compliant with HDMI CEC standards, featuring arbitration loss detection and automatic ACK output. Pin P8_5 serves as the CEC I/O terminal, and the internal CEC module operates at 32 kHz - enabling direct integration into TV, set-top box, or AV receiver designs without external transceivers.
How many A/D converter channels does the R5F3650KCNFB#V2 have, and what is their resolution and speed?
The R5F3650KCNFB#V2 integrates a 10-bit A/D converter with 26 input channels, including sample-and-hold functionality. Its conversion time is 1.72 µs per channel, supporting real-time acquisition from multiple sensors such as motor current shunts, temperature thermistors, and potentiometers. Channel selection is software-controlled, and conversions can be triggered by internal timers or external events.
What package type and pin count does the R5F3650KCNFB#V2 use, and is it RoHS-compliant?
The R5F3650KCNFB#V2 uses a 100-pin LQFP package designated PLQP0100KB-A (formerly 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm lead pitch. It is rated for -40°C to +85°C operation. Renesas confirms RoHS compliance for this part per J-STD-609 and JEDEC JESD204 standards, with lead-free matte tin plating and halogen-free molding compound.
Can the R5F3650KCNFB#V2 perform three-phase motor control without external gate drivers or timing logic?
Yes, the R5F3650KCNFB#V2 includes dedicated three-phase motor control circuitry with on-chip dead-time timer and complementary PWM outputs routed through Timer A1, A2, A4, and Timer B2. These outputs can directly drive external gate drivers, eliminating the need for discrete dead-time generators or external logic.
