Product details
Overview
R5F571MJHDBG#20 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, 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 multi-protocol fieldbus connectivity.
For engineers reviewing the R5F571MJHDBG#20 datasheet, R5F571MJHDBG#20 pinout, R5F571MJHDBG#20 application, or R5F571MJHDBG#20 equivalent, key selection criteria include IEEE 1588 timestamping accuracy, dual Ethernet channel isolation, 240-MHz deterministic interrupt latency, and integrated AES/SHA crypto acceleration for secure boot and OTA updates.
Technical Context
The R5F571MJHDBG#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions-enabling ultra-compact code density and single-cycle 32×32 multiply. Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash (100k erase cycles), and 512 KB SRAM split into wait-state-optimized regions (0–256 KB at 240 MHz, 256–512 KB at ≤120 MHz).
Real-time I/O control is enabled by three independent timer groups: MTU3a (9-channel, 16/32-bit, complementary PWM with dead-time generation), TPUa (6-channel, 16-bit, phase-counting mode), and GPTA (4-channel, synchronized 3-phase PWM). Communication is served by dual Ethernet MACs with EPTPC hardware timestamping, USBAa (HS USB 2.0 + BC1.2), SCIg/SCIh (9 total, LIN-capable), and CAN (3 modules, 32 mailboxes each).

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLHDBG#20 | Same RX71M family, identical 176-pin LFBGA package and 240-MHz core, but with 2.5 MB code flash and 384 KB SRAM instead of 4 MB/512 KB. | Suitable for cost-sensitive PLCs where firmware size and RAM footprint are constrained; lacks capacity for full-featured HMI or dual-protocol stacks. | Select when BOM cost reduction is prioritized over future firmware scalability and multi-interface concurrency. |
| R5F566TEHDFB#30 | RX66T group part: 160-MHz RXv3 core, 2 MB flash, 384 KB SRAM, single Ethernet MAC, no IEEE 1588, but enhanced motor control peripherals (32-bit GPTP, encoder interfaces). | Optimized for servo/inverter control with dedicated motor timing hardware; insufficient for dual-network redundancy or high-throughput secure gateway use. | Choose for standalone motor drive applications requiring higher-resolution PWM and encoder capture-not for networked industrial controllers needing dual Ethernet or crypto acceleration. |
Compared with R5F571MLHDBG#20, the R5F571MJHDBG#20 provides 1.5 MB more flash and 128 KB more SRAM for complex protocol stacks and GUI assets; versus R5F566TEHDFB#30, it trades motor-specific peripherals for dual IEEE 1588 Ethernet and hardware crypto-making it superior for networked control and secure edge nodes.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MJHDBG#20?
The R5F571MJHDBG#20 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32×32 multiply, and optimized instruction set-including floating-point and DSP extensions. The R5F571MJHDBG#20 maintains this performance across its full temperature range (–40°C to +85°C) with appropriate voltage and thermal design.
Does the R5F571MJHDBG#20 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F571MJHDBG#20 supports IEEE 1588 via its dedicated EPTPC (PTP Controller for Ethernet) hardware block, which is tightly coupled to both Ethernet MACs. It provides hardware timestamping of PTP event messages (Sync, Delay_Req, etc.) with sub-microsecond resolution, independent of CPU load. The R5F571MJHDBG#20 supports one-step and two-step clock correction modes and integrates with the MTU3a timer for precise clock servo loop implementation in master/slave configurations.
What are the flash and SRAM capacities of the R5F571MJHDBG#20, and how are they partitioned?
The R5F571MJHDBG#20 includes 4 MB of on-chip code flash memory (with background programming/erasing), 64 KB of reprogrammable data flash (rated for 100,000 erase/write cycles), 512 KB of general-purpose SRAM (split into two 256 KB banks with different wait-state behavior), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. The R5F571MJHDBG#20 uses these memory resources to support large real-time OS images, protocol stacks, and data buffers while ensuring reliability in industrial environments.
How many Ethernet MACs does the R5F571MJHDBG#20 integrate, and what physical layer interfaces do they support?
The R5F571MJHDBG#20 integrates two independent IEEE 802.3-compliant Ethernet MACs, each supporting 10/100 Mbps operation in full- and half-duplex modes. Both MACs support MII (Media Independent Interface) and RMII (Reduced MII) physical layer interfaces, allowing flexible PHY selection. The R5F571MJHDBG#20 also includes dedicated EDMAC channels and EPTPC hardware to offload PTP timestamping and frame processing from the CPU-enabling concurrent real-time control and network traffic handling.
What cryptographic functions are supported by the R5F571MJHDBG#20, and are they hardware-accelerated?
The R5F571MJHDBG#20 includes optional hardware-accelerated cryptographic functions: AES (128/192/256-bit keys), DES/T-DES, SHA-1, SHA-2 (224/256), and HMAC (160/224/256). These are implemented in dedicated on-chip engines that operate independently of the CPU-reducing encryption/decryption latency by >90% compared to software-only implementations. The R5F571MJHDBG#20 uses this acceleration for secure boot verification, firmware OTA updates, and TLS handshake offloading in industrial gateway applications.
