FAQ

What is the operating temperature range of the R5F3650ECDFB#30?

The R5F3650ECDFB#30 is rated for industrial operation from -40°C to +85°C. This extended temperature range is confirmed in Table 1.6 (D-Version product list) and supports deployment in demanding environments such as HVAC systems, factory automation controllers, and outdoor AV enclosures where ambient temperatures exceed commercial-grade limits.

Does the R5F3650ECDFB#30 support HDMI CEC functionality?

Yes, the R5F3650ECDFB#30 includes dedicated CEC transmit/receive circuitry compliant with the HDMI CEC standard, as specified in Section 1.2 (Table 1.2 and Table 1.4). It operates at 32 kHz, supports arbitration loss detection, and provides automatic ACK output - enabling full CEC protocol implementation without external components.

What package type and pin count does the R5F3650ECDFB#30 use?

The R5F3650ECDFB#30 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code: 100P6Q-A), as documented in Table 1.4 and Figure 1.7. This surface-mount package measures 14 mm × 14 mm with 0.5 mm pitch and supports both single-chip and external bus expansion modes.

How many A/D converter channels does the R5F3650ECDFB#30 provide?

The R5F3650ECDFB#30 integrates a 10-bit A/D converter with 26 input channels, including AN0_0–AN0_7, AN0–AN7, ANEX0/ANEX1, and ADTRG. Conversion time is 1.72 µs, and the module includes sample-and-hold functionality - enabling high-fidelity sensor acquisition in motor control and appliance monitoring applications.

Is the R5F3650ECDFB#30 pin-compatible with other M16C/65C Group MCUs?

Yes, the R5F3650ECDFB#30 shares identical pinout and package (100-pin LQFP PLQP0100KB-A) with other FB-suffixed variants like R5F3650ECNFB and R5F3651ECDFB, as verified in Tables 1.5–1.6 and Figures 1.6–1.7. This allows drop-in replacement within the same package family for memory or temperature grade upgrades.
