The device maintains full functionality across this range without derating.

Does the R5F3650MCDFB#V0 support hardware CEC functionality?

Yes, the R5F3650MCDFB#V0 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 is accessible via pin P8_5, as specified in Tables 1.4 and 1.10 of the datasheet.

What package type and dimensions does the R5F3650MCDFB#V0 use?

The R5F3650MCDFB#V0 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code: 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm lead pitch and an exposed thermal pad. This is confirmed in Figure 1.7 and Table 1.4 of the R01DS0015EJ0110 datasheet.

How many A/D converter channels does the R5F3650MCDFB#V0 provide, and what is their resolution?

The R5F3650MCDFB#V0 integrates a 10-bit A/D converter with 26 input channels, including sample-and-hold functionality. Conversion time is 1.72 µs, as stated in Table 1.4. Channels are distributed across ports P0, P2, P9, P10, and ANEX inputs, supporting simultaneous sampling in multi-sensor systems.

Is on-chip debug supported on the R5F3650MCDFB#V0, and what capabilities does it offer?

Yes, the R5F3650MCDFB#V0 features full on-chip debug with JTAG interface, on-board flash rewrite capability, and four address match interrupts. This enables real-time breakpoint setting, register inspection, and non-intrusive firmware validation without external emulators, as detailed in Section 1.2 and Table 1.4 of the datasheet.
