For engineers reviewing the R5F36506CDFB#V0 datasheet, R5F36506CDFB#V0 pinout, R5F36506CDFB#V0 application, or R5F36506CDFB#V0 equivalent, this page delivers verified package mapping (100-pin LQFP PLQP0100KB-A), confirmed peripheral integration (UART × 6, I²C × 1, PWM × 2), real-time clock, and CEC compliance for HDMI-CEC-enabled device design.

Technical Context

The R5F36506CDFB#V0 implements the M16C/60 CPU core with 16×16-bit multiplier and MAC instruction support, enabling deterministic motor control loop execution. Its clock system integrates main/sub oscillators, 125 kHz on-chip low-speed oscillator, 40 MHz ±5% high-speed on-chip oscillator, and PLL frequency synthesizer with selectable divide ratios (1/2/4/8/16).

Peripheral architecture includes dual 16-bit timer groups (Timer A × 5, Timer B × 6) supporting three-phase inverter control with on-chip dead-time generation, two remote control signal receivers (32 kHz operation), and multi-master I²C-bus interface - all mapped to dedicated pins in the 100-pin LQFP package without multiplexing conflicts.

FAQ

What is the operating temperature range of the R5F36506CDFB#V0?

The R5F36506CDFB#V0 is specified for operation from -40°C to +85°C, making it suitable for industrial environments and automotive cabin-adjacent applications where extended thermal stability is required. This rating is confirmed in Table 1.6 (D-Version) of the R01DS0015EJ0110 datasheet and distinguishes it from the N-Version variants like R5F36506CNFB#V0, which operate from -20°C to +85°C. The R5F36506CDFB#V0 maintains full functionality across this range without derating.

Does the R5F36506CDFB#V0 support HDMI CEC functionality?

Yes, the R5F36506CDFB#V0 includes dedicated CEC transmit/receive circuitry compliant with HDMI CEC standards, including hardware arbitration loss detection and automatic ACK output at 32 kHz. Pin P8_5 serves as the CEC I/O, and the feature is documented in Tables 1.2 and 1.4 of the R01DS0015EJ0110 datasheet. No external transceiver or firmware protocol stack is needed - the R5F36506CDFB#V0 handles physical layer timing and signal conditioning internally.

What package type is used for the R5F36506CDFB#V0?

The R5F36506CDFB#V0 uses a 100-pin LQFP package designated PLQP0100KB-A (previous code 100P6Q-A), measuring 14 mm × 14 mm with 0.5 mm pitch. This is confirmed in Table 1.6 (D-Version) and Figure 1.7 of the R01DS0015EJ0110 datasheet. It is distinct from the 128-pin variant (PLQP0128KB-A) and the 100-pin QFP variant (PRQP0100JD-B), both of which share the same memory configuration but differ in mechanical form factor and thermal performance.

How many A/D converter channels does the R5F36506CDFB#V0 have, and what is their resolution?

The R5F36506CDFB#V0 integrates a 10-bit resolution A/D converter with 26 input channels, including sample-and-hold functionality. Conversion time is 1.72 µs per channel, as specified in Table 1.2 and Table 1.4 of the R01DS0015EJ0110 datasheet. Channels are distributed across ports P0, P2, P9, P10, and P14 - enabling simultaneous monitoring of multiple sensors in motor control or environmental monitoring applications without external multiplexers.

Can the R5F36506CDFB#V0 be used for three-phase motor control?

Yes, the R5F36506CDFB#V0 supports hardware-accelerated three-phase motor control using Timer A1, A2, A4 and Timer B2 with integrated dead-time generation. This capability is explicitly listed under "Three-phase motor control timer functions" in Tables 1.2 and 1.4 of the R01DS0015EJ0110 datasheet. The on-chip dead-time timer eliminates external logic, and the 16-bit timers provide precise PWM edge placement for BLDC and PMSM commutation - validated in Renesas application notes for inverter reference designs.
