FAQ

What is the maximum operating frequency of the R5F56106WNBG#U0?

The R5F56106WNBG#U0 operates at a maximum frequency of 100 MHz, achieved via its on-chip PLL circuit which multiplies the input crystal or external clock signal. This frequency applies to the system clock (ICLK), under which the CPU, DMAC, DTC, ROM, and RAM operate synchronously. The peripheral module clock (PCLK) is independently configurable up to 50 MHz.

Does the R5F56106WNBG#U0 support external memory expansion?

Yes, the R5F56106WNBG#U0 supports external memory expansion through its dedicated external bus interface. It provides eight chip-select signals (CS0# to CS7#), each configurable for up to 16 Mbytes of address space, with selectable 8-bit or 16-bit data bus width and independent endian configuration per area-enabling direct connection to SDRAM, NOR flash, or FPGA peripherals.

How many analog-to-digital converter channels does the R5F56106WNBG#U0 include?

The R5F56106WNBG#U0 integrates four independent 10-bit A/D converter units, totaling 16 analog input channels (AN0–AN15). Each unit supports both single and continuous scan modes, with conversion start triggers available from software, timer outputs (TPU/TMR), or external signals-delivering 1.0 µs conversion time at 50-MHz PCLK operation.

What is the flash memory capacity of the R5F56106WNBG#U0?

The R5F56106WNBG#U0 contains 1 Mbyte of on-chip flash memory, organized for high-speed read/write operations and supporting three programming modes: SCI boot mode, user program mode, and user boot mode. This capacity is sufficient for medium-complexity firmware images in industrial control and office automation applications.

Which package type is used for the R5F56106WNBG#U0?

The R5F56106WNBG#U0 uses a 176-pin LFBGA package (PLBG0176GA-A) with 0.8 mm pitch and 12 mm × 12 mm body dimensions. This package provides high I/O density and thermal performance suitable for compact industrial and office equipment designs, and is RoHS compliant with lead-free termination.
