Product details
Overview
R5F571MJCGFC#V0 from Renesas is a 32-bit RXv2 microcontroller designed for high-performance industrial and networked embedded systems. It operates at up to 240 MHz (480 DMIPS), integrates 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN, and hardware AES/SHA encryption - enabling real-time control in smart gateways and PLCs.
For engineers reviewing the R5F571MJCGFC#V0 datasheet, R5F571MJCGFC#V0 pinout, R5F571MJCGFC#V0 application, or R5F571MJCGFC#V0 equivalent, this MCU delivers deterministic real-time execution, IEC 60730 safety support, low-power operation down to 0.2 mA/MHz, and dual Ethernet with PTP timestamping - critical for time-sensitive networking and functional safety designs.
Technical Context
The R5F571MJCGFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point math for motor control and signal processing. Its clock system supports external crystal (8–24 MHz) or internal PLL, with independent domain clocks: ICLK (240 MHz), PCLKA (120 MHz for Ethernet/USB/AES), and PCLKB (60 MHz for timers/ADC).
It features dual Ethernet controllers (ETHERC + EPTPCa) compliant with IEEE 802.3 and IEEE 1588-2008, each with dedicated EDMAC channels and hardware timestamping. The device includes two USB modules: USBAa (high-speed 480 Mbps with battery charging, exclusive to 176/177-pin packages) and USBb (full-speed 12 Mbps), plus three CAN channels (ISO 11898-1) with 32 mailboxes per channel.

The R5F571MJCGFC#V0 integrates two USB modules: USBAa (high-speed 480 Mbps with battery charging detection) and USBb (full-speed 12 Mbps). USBAa is available only on 176/177-pin packages like the R5F571MJCGFC#V0 and includes an on-chip transceiver, 8.5 KB RAM buffer, and OTG support. USBb supports low-speed mode (1.5 Mbps) in host configuration. Both modules eliminate external PHY requirements and support descriptor-based DMA transfers.
How many CAN channels and mailboxes does the R5F571MJCGFC#V0 support?
The R5F571MJCGFC#V0 integrates three independent CAN modules (CAN0–CAN2), each compliant with ISO 11898-1 and supporting standard and extended frames. Each channel provides 32 dedicated mailboxes with configurable priority, acceptance filtering, and automatic retransmission - enabling robust multi-node communication in automotive and industrial networks. This configuration is fixed for the R5F571MJCGFC#V0 and does not vary by package option.
