FAQ

What is the maximum operating frequency and supply voltage range for the R5F3640MCDFB#30?

The R5F3640MCDFB#30 operates at up to 25 MHz with VCC1 and VCC2 supplied between 2.7 V and 5.5 V. Its minimum instruction execution time is 40.0 ns under these conditions. The dual-supply architecture allows VCC2 to interface with external 3 V or 5 V buses independently of VCC1, enabling mixed-voltage system design without level shifters.

Does the R5F3640MCDFB#30 support hardware-based three-phase motor control?

Yes, the R5F3640MCDFB#30 integrates dedicated three-phase inverter control functions using Timer A1, A2, A4, and Timer B2. It provides on-chip dead time insertion, complementary PWM output generation, and U/V/W phase output pins - eliminating the need for external dead-time logic or complex software timing compensation in brushless DC or AC induction motor drives.

How many analog input channels does the R5F3640MCDFB#30 provide, and what is its A/D conversion speed?

The R5F3640MCDFB#30 features a 10-bit A/D converter with 26 input channels (AN0–AN7, AN0_0–AN0_7, AN2_0–AN2_7, ANEX0/ANEX1). Conversion time is 1.72 µs per sample, and it includes a sample-and-hold circuit to ensure accuracy during multiplexed acquisition across multiple sensors or signal sources.

What communication interfaces are integrated into the R5F3640MCDFB#30?

The R5F3640MCDFB#30 integrates UART0–UART2 and UART5–UART7 (6 asynchronous/clock-synchronous channels), SI/O3/SI/O4 (2 clock-synchronous serial), multi-master I2C-bus (1 channel), CEC transceiver (32 kHz), and IEBus-compatible serial interfaces. All UARTs support full hardware flow control (CTS/RTS) and configurable clock sources.

Is the R5F3640MCDFB#30 pin-compatible with other members of the M16C/64C Group?

Yes, all M16C/64C Group devices in the 100-pin LQFP package (PLQP0100KB-A), including R5F3640MCDFB#30, share identical pinouts and electrical characteristics. This enables direct substitution within the same package variant - for example, upgrading from R5F3640ECDFB to R5F3640MCDFB#30 requires no PCB changes, only firmware update to utilize additional program ROM and data flash.
