R5F3650NDFA#U0 from Renesas is a 16-bit M16C/60 Series CPU core microcontroller with 512 KB program ROM, 47 KB data flash, 16 KB RAM, and integrated peripherals including 10-bit A/D converter (26 channels), dual 8-bit D/A converters, CEC interface, and three-phase motor control timers. It operates at 32 MHz with 2.7–5.5 V supply and targets industrial and consumer equipment requiring real-time control and HDMI-CEC compliance.
For engineers reviewing the R5F3650NDFA#U0 datasheet, R5F3650NDFA#U0 pinout, R5F3650NDFA#U0 application, or R5F3650NDFA#U0 equivalent, key selection criteria include its -40°C to +85°C operating temperature, 100-pin QFP package (PRQP0100JD-B), CEC transceiver capability at 32 kHz, and on-chip dead-time timer for inverter control.
Technical Context
The R5F3650NDFA#U0 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction support, enabling efficient real-time signal processing. Its clock system integrates main/sub oscillators, 125 kHz and 40 MHz ±10% on-chip oscillators, and PLL frequency synthesizer with selectable divide ratios (1–16).
Peripheral integration includes six UART/serial interfaces (UART0–2, UART5–7), multi-master I²C-bus, two remote control signal receivers with 4-wave pattern matching, and a CRC calculator compliant with CRC-CCITT and CRC-16 standards - all supporting embedded control in noise-sensitive environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F3650NDFB#U0 | Same core, memory, and peripherals; differs only in package (100-pin LQFP PLQP0100KB-A vs. QFP PRQP0100JD-B). | Identical functional scope; selected when LQFP footprint or thermal profile is preferred over QFP. | Choose R5F3650NDFB#U0 if board layout requires LQFP or improved thermal dissipation under sustained load. |
| R5F3651NDFC#U0 | Higher memory: 512 KB program ROM + 47 KB data flash + 16 KB RAM, same package (128-pin LQFP), -40°C to +85°C rating. | Targeted at more complex firmware with larger code base or additional real-time tasks; not pin-compatible. | Select R5F3651NDFC#U0 only when 128-pin layout is available and expanded peripheral access (e.g., extra UART, timer channels) is required. |
Compared with R5F3650NDFB#U0, the R5F3650NDFA#U0 offers identical functionality in a QFP package optimized for cost-sensitive, high-volume consumer manufacturing; versus R5F3651NDFC#U0, it trades pin count and peripheral expansion for smaller footprint and lower BOM cost where full 128-pin resources are unnecessary.

This extended temperature grade supports deployment in industrial environments and automotive-adjacent applications where thermal stress exceeds commercial-grade limits. The device maintains full specification compliance across this range without derating.
Does the R5F3650NDFA#U0 include hardware support for HDMI-CEC?
Yes, the R5F3650NDFA#U0 integrates dedicated CEC circuitry compliant with HDMI CEC standards, including transmit/receive capability, arbitration lost detection, and automatic ACK output - all operating at 32 kHz. Pin P8_5 serves as the shared CEC I/O, and the function is explicitly documented in Tables 1.2 and 1.4 of the R01DS0031EJ0210 datasheet.
What package type is used for the R5F3650NDFA#U0?
The R5F3650NDFA#U0 uses the 100-pin QFP package with code PRQP0100JD-B (previous code: 100P6F-A), as specified in Table 1.5 of the R01DS0031EJ0210 datasheet. This package has 0.65 mm lead pitch, 14 × 20 mm body size, and is lead-free and RoHS-compliant - suitable for automated SMT assembly.
How many A/D converter channels does the R5F3650NDFA#U0 support?
The R5F3650NDFA#U0 features a 10-bit A/D converter with 26 input channels, including dedicated AN0–AN7, ANEX0/ANEX1, ADTRG, and multiple AN2_x inputs. Conversion time is 1.72 µs, and sample-and-hold functionality is integrated - all confirmed in Table 1.2 and Table 1.4 of the R01DS0031EJ0210 datasheet.
Is the R5F3650NDFA#U0 pin-compatible with other M16C/65 Group MCUs?
No - the R5F3650NDFA#U0 is not universally pin-compatible across the M16C/65 Group. While it shares the 100-pin QFP footprint with variants like R5F3650NDFB#U0, it differs from 128-pin variants (e.g., R5F3651NDFC#U0) in pin count, signal mapping, and peripheral allocation. Pin compatibility must be verified per specific variant using Figures 1.6–1.7 and Tables 1.10–1.11 in the datasheet.
