FAQ

What is the maximum operating frequency and supply voltage range for the R5F3650KCDFB#30?

The R5F3650KCDFB#30 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, the minimum instruction execution time is 31.25 ns under nominal conditions (VCC1 = VCC2 = 2.7–5.5 V). The high-speed on-chip oscillator (40 MHz ±5%) feeds the PLL for precise clock synthesis.

Does the R5F3650KCDFB#30 support CEC functionality, and how is it implemented?

Yes, the R5F3650KCDFB#30 integrates full CEC (Consumer Electronics Control) functionality on Pin P8_5 (NMI/SD/CEC). It supports CEC transmit/receive, arbitration lost detection, and automatic ACK output at 32 kHz, complying with HDMI CEC standards. No external transceiver is required, reducing BOM count and PCB area.

What package type and pin count does the R5F3650KCDFB#30 use?

The R5F3650KCDFB#30 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code: 100P6Q-A), with 14 mm × 14 mm body size and 0.5 mm lead pitch. This package is distinct from the 128-pin variant (PLQP0128KB-A) and shares footprint compatibility with other FB-suffixed M16C/65C devices.

How many A/D and D/A converter channels does the R5F3650KCDFB#30 include?

The R5F3650KCDFB#30 includes a 10-bit A/D converter with 26 input channels (including AN0_0–AN0_7, AN0–AN7, ANEX0/ANEX1) and two independent 8-bit D/A converters (DA0 and DA1 on P9_3/P9_4). Conversion time is 1.72 µs, and sample-and-hold is integrated for accurate multi-channel acquisition.

Is on-chip debug supported on the R5F3650KCDFB#30, and what capabilities does it provide?

Yes, the R5F3650KCDFB#30 features full on-chip debug support including real-time flash rewrite, address match interrupts (×4), and non-intrusive program execution monitoring. Debug access requires only the standard SWJ interface-no external emulator is needed, simplifying development and field firmware updates.
