Product details
Overview
R5F56316CDFP#V0 from Renesas is a 100 MHz 32-bit RXv1 CPU-based microcontroller in the RX63N Group, featuring on-chip FPU (IEEE-754 single-precision), 165 DMIPS performance, 1.5 MB flash, 192 KB SRAM, and integrated Ethernet MAC (10/100 Mbps MII/RMII). It supports real-time control in industrial gateways requiring deterministic USB 2.0 host/function/OTG, CAN 2.0B (3 channels), and dual 10-bit DACs.
For engineers reviewing the R5F56316CDFP#V0 datasheet, R5F56316CDFP#V0 pinout, R5F56316CDFP#V0 application, or R5F56316CDFP#V0 equivalent, key selection criteria include Ethernet MAC integration, 100 MHz timing-critical peripheral clocking (ICLK/PCLK), 176-pin LQFP package with 133 GPIOs (18× 5-V tolerant), and IEC60730-compliant safety features including CRC, self-diagnostic A/D, and oscillation-stop detection.
Technical Context
The R5F56316CDFP#V0 implements the RXv1 core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dedicated hardware accelerators: DEU for AES-128/192/256 encryption/decryption (ECB/CBC), MTU2/TPU timers for PWM generation and phase counting, and EDMAC for Ethernet DMA offload.
Its clock system includes PLL, 125-kHz LOCO, 50-MHz HOCO, and subclock oscillator - all independently configurable for ICLK (up to 100 MHz), PCLK (up to 50 MHz), FCLK (50 MHz), and BCLK (50 MHz). The MCU supports four low-power modes (sleep, all-module stop, software standby, deep software standby) with RTC battery backup and 2.7–3.6 V operation.
