The R5F3650NDFB#10 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. Its minimum instruction execution time is 31.25 ns under these conditions, enabling deterministic real-time control in motor and power applications. The dual-supply architecture allows VCC2 to interface with external 3V or 5V peripherals independently of VCC1.
Does the R5F3650NDFB#10 support HDMI Consumer Electronics Control (CEC) functionality?
Yes, the R5F3650NDFB#10 integrates a dedicated CEC transceiver on pin P8_5, supporting full CEC v1.4 transmit/receive, arbitration loss detection, and automatic ACK generation at 32 kHz. This eliminates the need for external CEC PHY components in TV, AV receiver, and set-top box designs, reducing bill-of-materials cost and PCB area.
What are the A/D and D/A converter specifications of the R5F3650NDFB#10?
The R5F3650NDFB#10 features a 10-bit A/D converter with 26 input channels and sample-and-hold circuitry, achieving 1.72 µs conversion time. It also includes two independent 8-bit D/A converters (DA0 and DA1 on P9_3/P9_4) for analog output generation - suitable for audio tone generation, sensor biasing, or actuator reference signals in closed-loop systems.
Which package type and pin count does the R5F3650NDFB#10 use?
The R5F3650NDFB#10 uses a 100-pin LQFP package designated PLQP0100KB-A (14 mm × 14 mm, 0.5 mm pitch). This package replaces the older 100P6Q-A code and is RoHS compliant. It provides 85 CMOS I/O ports with selectable pull-up resistors and 3 N-channel open-drain outputs, optimized for high-density industrial PCB layouts.
What motor control capabilities does the R5F3650NDFB#10 offer?
The R5F3650NDFB#10 includes hardware-accelerated three-phase motor control with dedicated timer resources (TA1, TA2, TA4, TB2), on-chip dead-time insertion, and complementary PWM outputs.
