FAQ

What is the maximum operating frequency of the R5F56106VNFP#V0?

The R5F56106VNFP#V0 operates at a maximum frequency of 100 MHz. This is achieved using the on-chip PLL circuit with an external crystal (1–20 MHz) or external clock input. The CPU, DMAC, DTC, ROM, and RAM run synchronously with the system clock (ICLK), which is configurable between 8 MHz and 100 MHz per the datasheet specifications.

Does the R5F56106VNFP#V0 support IEEE 754-compliant floating-point operations?

Yes, the R5F56106VNFP#V0 includes a single-precision (32-bit) floating-point unit (FPU) that fully conforms to the IEEE 754 standard. It supports standard data types and floating-point exceptions, enabling robust numerical computation in control algorithms, sensor fusion, and signal processing without external coprocessors.

How many analog-to-digital converter (ADC) channels does the R5F56106VNFP#V0 provide?

The R5F56106VNFP#V0 integrates four independent 10-bit ADC units, totaling 16 input channels (AN0–AN15). Each unit supports single-scan and continuous-scan modes, with conversion time of 1.0 µs per channel at 50-MHz peripheral clock (PCLK), and trigger sources including software, timer outputs, and external signals.

What package type is used for the R5F56106VNFP#V0?

The R5F56106VNFP#V0 uses a 144-pin LQFP package (PLQP0144KA-A), measuring 20 mm × 20 mm with 0.5 mm pitch. This package provides 117 general-purpose I/O pins, including 10 × 5-V tolerant inputs and 16 × open-drain outputs, and is compatible with standard surface-mount assembly processes.

Can the R5F56106VNFP#V0 interface with external memory devices?

Yes, the R5F56106VNFP#V0 features a full external bus interface supporting eight independently configurable chip-select areas (CS0–CS7), each with up to 16 MB address space. It supports 8-bit or 16-bit data bus widths, wait-state control, write buffering, and little/big-endian data arrangement per area - enabling direct connection to SDRAM, NOR flash, or peripheral LSI.
