FAQ
What is the maximum operating frequency of the R5F56108VNFP#H0?
The R5F56108VNFP#H0 operates at a maximum system clock frequency of 100 MHz (ICLK). This is achieved using its on-chip PLL circuit with configurable multiplication/division ratios. The peripheral module clock (PCLK) runs up to 50 MHz, and the external bus clock (BCLK) up to 25 MHz - all independently controlled to optimize performance and power per subsystem. The R5F56108VNFP#H0 achieves one instruction per cycle at this speed due to its RXv1 CPU architecture.
Does the R5F56108VNFP#H0 support IEEE 754-compliant floating-point operations?
Yes, the R5F56108VNFP#H0 includes a hardware single-precision (32-bit) floating-point unit (FPU) that fully complies with the IEEE 754 standard. It supports all basic arithmetic operations, comparisons, and exceptions defined in the standard. This FPU accelerates computationally intensive tasks such as motor control algorithms, sensor fusion, and digital filtering - eliminating reliance on slower software libraries. The R5F56108VNFP#H0 executes floating-point instructions natively within the RXv1 instruction set.
How many analog-to-digital converter (A/D) channels does the R5F56108VNFP#H0 provide?
The R5F56108VNFP#H0 integrates four independent 10-bit A/D converter units, each with four input channels, for a total of 16 analog input channels. Each unit supports single-scan, continuous-scan, and triggered conversion modes. Conversion time is 1.0 µs per channel when operating at 50 MHz PCLK. Inputs can be started by software, timer events (TPU/TMR), or external signals - enabling precise synchronization with motor commutation or sensor sampling windows. The R5F56108VNFP#H0 also provides dedicated VREFH/VREFL pins for accurate reference voltage control.
What package type and pin count does the R5F56108VNFP#H0 use?
The R5F56108VNFP#H0 uses a 144-pin LQFP package (PLQP0144KA-A), measuring 20 mm × 20 mm with 0.5 mm pin pitch. It provides 117 general-purpose I/O pins, including 10 × 5-V-tolerant inputs, 16 × open-drain outputs, and 40 × programmable pull-up resistors. Pin functions include JTAG debug (TCK/TDI/TMS/TRST#), dual D/A outputs (DA0/DA1), 16-channel A/D inputs (AN0–AN15), and external bus signals (CS0#–CS7#, RD#, WR#, BCLK). The R5F56108VNFP#H0 shares pin compatibility with other RX610 Group members in the same package variant.
Can the R5F56108VNFP#H0 operate in low-power modes for battery-powered applications?
Yes, the R5F56108VNFP#H0 supports four distinct power-down modes: Sleep mode, all-module clock stop mode, software standby mode, and deep software standby mode. In deep software standby, current consumption drops to microampere levels while retaining full RAM content and enabling wake-up via IRQ, NMI, or reset. The module stop function allows selective clock gating to unused peripherals. These capabilities make the R5F56108VNFP#H0 suitable for portable test equipment or remote industrial sensors where energy efficiency is critical. The R5F56108VNFP#H0's power management is configured entirely in software without external components.
