FAQ
What is the maximum operating frequency and supply voltage range for the R5F64168DFB#U0?
The R5F64168DFB#U0 operates at a maximum frequency of 64 MHz with a supply voltage range of 3.0 V to 5.5 V. This allows direct compatibility with both legacy 5 V logic families and modern 3.3 V peripheral ICs without level-shifting circuitry. The device achieves 15.625 ns minimum instruction execution time at full speed, supporting hard real-time deadlines in motor control loops.
Does the R5F64168DFB#U0 include an integrated floating-point unit (FPU)?
Yes, the R5F64168DFB#U0 integrates an IEEE-754 compatible single-precision FPU.

How many analog-to-digital converter (ADC) channels does the R5F64168DFB#U0 support?
The R5F64168DFB#U0 supports 26 channels of 10-bit analog-to-digital conversion with integrated sample-and-hold functionality. This count is specific to the 100-pin package variant (R5F64168DFB#U0), as confirmed in Table 1.4 of the R01DS0063EJ0120 datasheet. The 144-pin variant offers 34 channels, but R5F64168DFB#U0 implements the full 26-channel capability within its pinout constraints.
What serial communication interfaces are available on the R5F64168DFB#U0?
The R5F64168DFB#U0 provides nine asynchronous/synchronous serial interface channels (UART0–UART8), with I²C-bus capability on UART0–UART6, plus one dedicated multi-master I²C-bus interface. All nine UART channels support full-duplex operation with RTS/CTS flow control, and six support special modes including IEBus (optional). This enables concurrent connection to displays, sensors, and external controllers without multiplexing overhead.
Is the R5F64168DFB#U0 pin-compatible with other devices in the R32C/116 Group?
Yes, the R5F64168DFB#U0 shares identical pinout and peripheral mapping with other 100-pin R32C/116 Group variants such as R5F64165DFB#U0, R5F64166DFB#U0, and R5F64167DFB#U0. This ensures drop-in replacement capability within the same package family - allowing firmware reuse and simplified BOM management when scaling flash/RAM capacity across designs using the R5F64168DFB#U0 platform.
