Yes, the R5F3650MDFB#V2 integrates dedicated CEC transmit/receive circuitry compliant with HDMI CEC standards, including arbitration loss detection and automatic ACK output. The CEC function operates at 32 kHz and shares Pin P8_5 (NMI/SD/CEC), requiring configuration during reset initialization to assign CEC functionality.
How many analog-to-digital converter channels does the R5F3650MDFB#V2 support, and what is their resolution?
The R5F3650MDFB#V2 includes a 10-bit A/D converter with 26 input channels and sample-and-hold capability. Conversion time is 1.72 µs per sample. Channels are distributed across Ports P0, P2, P10, and P9, supporting simultaneous sampling in multi-channel configurations - essential for sensor fusion in industrial control applications.
What package type and pin count does the R5F3650MDFB#V2 use?
The R5F3650MDFB#V2 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code: 100P6Q-A), with 0.5 mm pin pitch and 14 mm × 14 mm body size. This package is distinct from the 100-pin QFP (PRQP0100JD-B) used by R5F3650MDFA#V2 and the 128-pin LQFP used by R5F3651MDFC#V2.
Can the R5F3650MDFB#V2 perform three-phase motor control without external components?
Yes, the R5F3650MDFB#V2 contains dedicated three-phase inverter control hardware using Timer A1, A2, A4, and Timer B2, along with an on-chip dead-time timer.
