For engineers reviewing the R5F56104VNFP#V0 datasheet, R5F56104VNFP#V0 pinout, R5F56104VNFP#V0 application, or R5F56104VNFP#V0 equivalent, key selection criteria include its 144-pin LQFP package, 100 MHz max operating frequency, 3.0–3.6 V supply range, −20 to +85°C temperature grade, and support for external bus expansion across eight chip-select zones - critical for legacy interface bridging and memory-mapped peripheral integration.

Technical Context

The R5F56104VNFP#V0 implements the RXv1 CPU architecture with IEEE 754-compliant single-precision FPU, 32×32→64-bit multiplier, and 32/32→32-bit divider. Its interrupt controller supports 116 peripheral interrupts and 16 external IRQ pins with eight priority levels, enabling hard real-time task scheduling in motion control firmware.

Clock generation includes a PLL with independent system (ICLK), peripheral (PCLK), and external bus (BCLK) domains - configurable from 8 to 100 MHz (ICLK), 8 to 50 MHz (PCLK), and 8 to 25 MHz (BCLK). The on-chip bus controller supports 16-Mbyte addressable spaces per CS area with selectable 8-/16-bit data bus width and endian per region.

FAQ

What is the maximum operating frequency and voltage range for the R5F56104VNFP#V0?

The R5F56104VNFP#V0 operates at a maximum frequency of 100 MHz with a supply voltage range of 3.0 V to 3.6 V for VCC, PLLVCC, AVCC, and VREFH. This ensures stable high-speed execution while maintaining compatibility with standard 3.3 V industrial power rails and minimizing noise coupling into analog sections.

Does the R5F56104VNFP#V0 support external memory expansion, and what interface options are available?

Yes, the R5F56104VNFP#V0 supports external memory expansion via an 8-area external bus controller (CS0–CS7), each configurable for 16 Mbytes address space, 8- or 16-bit data bus width, and independent endian selection. Signals include WR#, RD#, BCLK, WAIT#, and address lines A0–A23 - enabling direct connection to NOR flash, SRAM, or FPGA peripherals without external logic.

How many analog-to-digital and digital-to-analog converter channels does the R5F56104VNFP#V0 integrate?

The R5F56104VNFP#V0 integrates four independent 10-bit A/D converter units (each with four channels, totaling 16 analog inputs) and two 10-bit D/A converter channels. Conversion time is 1.0 µs per channel at 50 MHz PCLK, and both ADC and DAC support hardware trigger sources including TPU and CMT outputs for synchronized sampling and waveform generation.

What debug and programming interfaces are supported by the R5F56104VNFP#V0?

The R5F56104VNFP#V0 supports on-chip debugging via SWD using dedicated pins TDI, TDO, TCK, TMS, and TRST#. It also supports SCI boot mode for in-system programming through any of its seven serial channels, allowing firmware updates without JTAG hardware - essential for field-deployed equipment maintenance.

Is the R5F56104VNFP#V0 pin-compatible with other RX610 Group members, and what package does it use?

Yes, the R5F56104VNFP#V0 uses the 144-pin LQFP package (PLQP0144KA-A) and is fully pin-compatible with other RX610 Group variants in the same package, including R5F56106VNFP and R5F56108VNFP. All share identical pin functions, electrical characteristics, and mechanical footprint - enabling drop-in replacement for flash capacity scaling without PCB revision.
