The peripheral module clock (PCLK) is independently configurable up to 50 MHz, and the external bus clock (BCLK) supports up to 25 MHz for memory expansion.
Does the R5F56106WDBG#U0 include a floating-point unit?
Yes, the R5F56106WDBG#U0 integrates a single-precision (32-bit) floating-point calculation unit compliant with the IEEE 754 standard. It supports eight floating-point operation instructions and is tightly coupled to the RX CPU core, enabling efficient execution of math-intensive algorithms such as PID control, sensor fusion, and digital filtering without external co-processors.
How many analog-to-digital converter channels does the R5F56106WDBG#U0 support?
The R5F56106WDBG#U0 includes four independent 10-bit A/D converter units, providing a total of 16 analog input channels (AN0–AN15). Each unit supports single-mode and scan-mode operation, with conversion time of 1.0 µs per channel at 50 MHz peripheral clock (PCLK), and supports software, timer-triggered, or external signal–triggered conversion starts.
What package type is used for the R5F56106WDBG#U0?
The R5F56106WDBG#U0 is housed in a 176-pin LFBGA package (PLBG0176GA-A), measuring 10 mm × 10 mm with 0.8 mm ball pitch. This package includes an exposed thermal pad for enhanced heat dissipation and supports high-density PCB layouts required for industrial control and office automation applications.
What are the power supply requirements for the R5F56106WDBG#U0?
The R5F56106WDBG#U0 requires three primary supply domains: VCC and VSS (3.0 V to 3.6 V core/system I/O), AVCC and AVSS (3.0 V to 3.6 V analog section), and PLLVCC/PLLVSS (dedicated 3.0 V to 3.6 V PLL supply). VREFH must be between 3.0 V and AVCC, and VREFL is typically tied to AVSS. Decoupling capacitors (e.g., 0.1 µF) are required near VCL and all power pins.
