Renesas R5F571MJHDFB#30

Overview

R5F571MJHDFB#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and dual 12-bit A/D converters (29 total channels). It targets industrial automation controllers requiring deterministic real-time networking, secure firmware updates, and mixed-signal edge processing.

For engineers reviewing the R5F571MJHDFB#30 datasheet, R5F571MJHDFB#30 pinout, R5F571MJHDFB#30 application, or R5F571MJHDFB#30 equivalent, key selection criteria include IEEE 1588 PTP timestamping accuracy, dual Ethernet channel isolation, 240-MHz real-time interrupt latency, hardware AES/SHA acceleration, and support for IEC 60730 Class B functional safety diagnostics.

Technical Context

The R5F571MJHDFB#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent Ethernet MACs with dedicated EPTPC (IEEE 1588) and EDMAC controllers - each with separate 2 KB TX / 4 KB RX FIFOs and MII/RMII interface support.

Its memory subsystem includes 4 MB code flash (0-wait ≤120 MHz), 64 KB data flash (100k write cycles), 512 KB SRAM (split into 256 KB zero-wait ICLK domains), and 32 KB ECCRAM with SEC-DED error correction. Clock generation supports PLL multiplication of HOCO (16–20 MHz) or external crystal (8–24 MHz) to achieve 240 MHz ICLK while maintaining independent PCLKA (≤120 MHz), PCLKB (≤60 MHz), and ADCLK (≤60 MHz) domains.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MJHDFB#30?

The R5F571MJHDFB#30 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved through its optimized RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiply, and zero-wait access to 256 KB of SRAM at full speed. The R5F571MJHDFB#30 maintains this performance while supporting concurrent Ethernet, USB, and CAN traffic without throttling.

Does the R5F571MJHDFB#30 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F571MJHDFB#30 includes a dedicated EPTPC (Ethernet PTP Controller) block compliant with IEEE 1588-2008. It provides hardware timestamping of Ethernet frames with sub-100 ns resolution, independent of CPU load. This capability is essential for R5F571MJHDFB#30-based devices implementing time-sensitive networking in industrial automation and smart grid applications.

How many Ethernet MAC interfaces does the R5F571MJHDFB#30 integrate, and what PHY interfaces are supported?

The R5F571MJHDFB#30 integrates two fully independent IEEE 802.3-compliant 10/100 Mbps Ethernet MACs. Each supports MII and RMII physical layer interfaces, enabling direct connection to external PHYs. The R5F571MJHDFB#30 also includes dedicated EDMAC channels (3 total: 2 for ETHERC, 1 for EPTPC) and 2 KB TX / 4 KB RX FIFOs per MAC to offload CPU bandwidth.

What are the memory resources available on the R5F571MJHDFB#30?

The R5F571MJHDFB#30 provides 4 MB of on-chip code flash memory (0-wait access ≤120 MHz), 64 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), 512 KB of SRAM (with 256 KB zero-wait at 240 MHz), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. These resources are fully accessible to the R5F571MJHDFB#30's RXv2 core without external memory expansion.

Is the R5F571MJHDFB#30 qualified for industrial temperature range and functional safety standards?

Yes, the R5F571MJHDFB#30 is rated for the industrial temperature range of –40°C to +85°C (D-version) and includes built-in features for IEC 60730 Class B compliance: oscillation-stop detection, hardware CRC engine, windowed independent watchdog timer (IWDTa), A/D converter self-diagnostic, and register write protection.
