Renesas R5F56308CDFP#V0

Overview

R5F56308CDFP#V0 from Renesas is a 100-MHz 32-bit RX CPU-based microcontroller with on-chip FPU, 512-Kbyte flash, 64-Kbyte SRAM, and 32-Kbyte data flash. It integrates USB 2.0 full-speed, CAN, 12-bit/10-bit A/D converters (21/8 channels), dual 10-bit D/A, RTC, and up to 148 GPIO pins. It targets industrial motor control and embedded HMI applications requiring deterministic real-time response and IEC60730 compliance.

For engineers reviewing the R5F56308CDFP#V0 datasheet, R5F56308CDFP#V0 pinout, R5F56308CDFP#V0 application, or R5F56308CDFP#V0 equivalent, key selection criteria include its 100-MHz operation with 165 DMIPS, integrated floating-point unit for motion control math, 32-Kbyte reprogrammable data flash for firmware updates, and support for CAN 2.0B with 32 mailboxes per channel.

Technical Context

The R5F56308CDFP#V0 implements the RXv1 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It supports IEEE-754 single-precision floating-point operations and includes two multiply-and-accumulate units - one for memory-to-memory and one for register-to-register execution.

Its clock system combines external crystal (4–16 MHz) with internal PLL, HOCO (50 MHz), LOCO (125 kHz), and sub-clock (32 kHz) sources, allowing independent frequency division for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (up to 50 MHz), and BCLK (up to 50 MHz). The MCU provides four low-power modes and battery-backed RTC operation down to 2.3 V.

FAQ

What is the maximum operating frequency and CPU performance of the R5F56308CDFP#V0?

The R5F56308CDFP#V0 operates at a maximum system clock frequency of 100 MHz and delivers 165 DMIPS of processing performance using the RXv1 32-bit CPU core. Its single-cycle 32×32 multiplier and hardware floating-point unit enable deterministic execution of motion control algorithms and digital signal processing tasks without software emulation overhead. This performance level is fully sustained across the -40°C to +85°C operating range.

Does the R5F56308CDFP#V0 support IEC60730 Class B compliance features?

Yes, the R5F56308CDFP#V0 integrates dedicated hardware features for IEC60730 Class B compliance, including oscillation-stop detection, built-in CRC calculator with three polynomial options, independent watchdog timer (IWDT) with dedicated clock source, and self-diagnostic functions for the 10-bit A/D converter. These capabilities are documented in the RX630 Group hardware manual and enable certified safety firmware implementation without external components.

What package type and pin count does the R5F56308CDFP#V0 use?

The R5F56308CDFP#V0 uses the PLQP0100KB-A package: a 100-pin LQFP with 14 × 14 mm body size and 0.5-mm pin pitch. This RoHS-compliant package includes an exposed thermal pad and supports 148 general-purpose I/O pins, with 54 pins rated for 5-V tolerance. Pin functions are fully defined in the R01DS0060EJ0160 datasheet Section 1.4.
