Technical Context

The R5F56106WNBG#G0 implements the RX CPU core with single-cycle instruction execution, IEEE 754-compliant single-precision FPU, 32×32→64-bit multiplier, and 32/32→32-bit divider. Its memory subsystem includes on-chip flash with three programming modes (SCI boot, user program, user boot) and 32 Kbytes of data flash supporting EEPROM-like write endurance.

Peripheral timing is decoupled: CPU and RAM run at ICLK (8–100 MHz), peripherals at PCLK (8–50 MHz), and external bus at BCLK (8–25 MHz). Interrupt handling supports 116 peripheral sources, 16 external IRQ pins, and eight priority levels with non-maskable NMI input.

FAQ

What is the maximum operating frequency of the R5F56106WNBG#G0?

The R5F56106WNBG#G0 supports a maximum operating frequency of 100 MHz for its RX CPU core. This is achieved using the on-chip PLL circuit with an external crystal (XTAL/EXTAL) and internal frequency dividers. System clock (ICLK), peripheral clock (PCLK), and external bus clock (BCLK) are independently configurable within 8–100 MHz, 8–50 MHz, and 8–25 MHz ranges respectively, allowing optimized timing for CPU, peripherals, and external memory access.

Does the R5F56106WNBG#G0 include a hardware floating-point unit?

Yes, the R5F56106WNBG#G0 includes a single-precision (32-bit) floating-point unit compliant with IEEE 754 standards. This FPU accelerates mathematical operations such as trigonometric functions, square roots, and division-critical for real-time motor control, sensor fusion, and digital power supply algorithms-without relying on slower software emulation libraries.

How many analog-to-digital converter channels does the R5F56106WNBG#G0 support?

The R5F56106WNBG#G0 integrates four independent 10-bit A/D converter units, each with four input channels, for a total of 16 analog inputs. Conversion time is 1.0 µs per channel at 50-MHz PCLK, and start triggers can be generated by software, timer outputs (TPU/TMR), or external signals-enabling synchronized sampling across multiple sensors in industrial monitoring applications.

What package type is used for the R5F56106WNBG#G0?

The R5F56106WNBG#G0 uses a 176-pin LFBGA package (PLBG0176GA-A), measuring 10 mm × 10 mm with 0.8 mm pitch and a bottom thermal pad. This package supports 140 general-purpose I/O pins, including 10 5-V tolerant inputs, and is optimized for high-density industrial PCB layouts where thermal performance and signal integrity are critical.

Can the R5F56106WNBG#G0 operate in low-power modes for battery-powered applications?

Yes, the R5F56106WNBG#G0 supports four distinct power-down modes: Sleep, All-Module Clock Stop, Software Standby, and Deep Software Standby. These modes reduce current consumption significantly while retaining RAM content and enabling wake-up via external interrupts, timer events, or RTC alarms-making it suitable for intermittent-sensing applications like portable diagnostic tools or wireless sensor nodes where runtime efficiency is essential.
