Product details
Overview
R5F571MJDDLC#20 from Renesas is a 240-MHz 32-bit RXv2 microcontroller with single-precision IEEE-754 FPU, 480 DMIPS performance, 4-MB on-chip code flash, 512-KB SRAM (including 32-KB ECCRAM), and integrated IEEE 1588-compliant Ethernet MAC, high-speed USB 2.0 with battery charging, CAN, SD host interface, and dual 12-bit A/D converters. It targets industrial automation controllers requiring deterministic real-time response, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MJDDLC#20 datasheet, R5F571MJDDLC#20 pinout, R5F571MJDDLC#20 application, or R5F571MJDDLC#20 equivalent, key selection criteria include its 177-pin TFLGA package, 240-MHz CPU clock with no-wait access up to 120 MHz on flash, dual Ethernet channels with PTP support, hardware AES/SHA encryption, and IEC60730 safety features including oscillation-stop detection and A/D self-diagnosis.
Technical Context
The R5F571MJDDLC#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual independent clock domains: ICLK up to 240 MHz for CPU execution and PCLKA up to 120 MHz for Ethernet, USB, and AES peripherals - enabling concurrent high-bandwidth data movement and deterministic control.
Its peripheral subsystem includes three CAN modules (32 mailboxes each), two IEEE 1588-compliant Ethernet MACs with EPTPC and EDMAC support, and a dedicated EXDMAC controller with cluster transfer mode - all coordinated via the Event Link Controller (ELC) to eliminate CPU intervention for time-critical signal chaining like PWM-triggered A/D capture or RTC-alarm-initiated wake-up from deep software standby.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MJDDEA#20 | Same RX71M core, identical peripherals, but in 176-pin LFBGA (PLQP0176KB-A) instead of 177-pin TFLGA; 1 mm larger footprint, 0.8-mm pitch. | LFBGA offers better thermal dissipation for continuous 240-MHz operation in enclosed enclosures; less suitable for ultra-thin HMI designs. | Select R5F571MJDDEA#20 when board-level reflow compatibility with standard LFBGA processes is prioritized over minimal footprint. |
| R5F571MJDLF#20 | Same 177-pin TFLGA package but with 2-MB code flash (vs. 4 MB) and no SDHI interface; otherwise identical clock, memory, and peripheral specs. | Targeted at cost-sensitive applications where local SD card logging is unnecessary and firmware size remains under 2 MB. | Choose R5F571MJDLF#20 to reduce BOM cost where full 4-MB flash capacity and SDHI are unused in final design. |
Compared with R5F571MJDDLC#20, R5F571MJDDEA#20 trades compactness for thermal robustness in LFBGA packaging, while R5F571MJDLF#20 reduces flash and removes SDHI to lower cost - both retain identical real-time performance, safety features, and dual-Ethernet/USB-CAN connectivity.

FAQ
What is the maximum operating frequency and flash access performance of the R5F571MJDDLC#20?
The R5F571MJDDLC#20 operates at a maximum CPU frequency of 240 MHz. Its 4-MB on-chip code flash delivers zero wait-state access for instructions and operands when the Address Fetch Unit (AFU) hits, up to 120 MHz. Above 120 MHz, one wait state applies when the AFU misses. This enables deterministic real-time execution critical for motion control and industrial communication stacks.
Does the R5F571MJDDLC#20 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F571MJDDLC#20 includes a dedicated PTP controller (EPTPCa) compliant with IEEE 1588-2008. It is hardware-integrated with both Ethernet MAC channels, enabling timestamp insertion and extraction on transmit/receive frames with sub-microsecond resolution. The EPTPCa synchronizes to the system clock and supports master/slave operation for time-critical distributed control networks.
What safety certifications and built-in diagnostics does the R5F571MJDDLC#20 provide for IEC60730 compliance?
The R5F571MJDDLC#20 includes multiple IEC60730 Class B support features: oscillation-stoppage detection, hardware CRC calculation unit, independent watchdog timer (IWDTa) with configurable window function, A/D converter self-diagnostic capability, and register write protection. These reduce external component count and simplify certification evidence for household and industrial appliances.
How many Ethernet and USB interfaces does the R5F571MJDDLC#20 integrate, and what are their key capabilities?
The R5F571MJDDLC#20 integrates two IEEE 802.3-compliant Ethernet MACs supporting 10/100 Mbps full/half-duplex with MII/RMII, plus a dedicated PTP controller and 3-channel EDMAC. It also includes one high-speed USB 2.0 module (480 Mbps) with battery charging support and one full-speed USB 2.0 module - both with integrated transceivers eliminating external PHY components.
What is the package type and pin count of the R5F571MJDDLC#20, and what are its key mechanical attributes?
The R5F571MJDDLC#20 uses the PTLG0177KA-A package: a 177-pin Thin Fine-Pitch Land Grid Array measuring 8 mm × 8 mm with 0.5-mm pitch and 0.75-mm height. It features RoHS-compliant, lead-free matte tin terminations and is rated for operation from –40°C to +105°C, making it suitable for space-constrained industrial and medical applications requiring high I/O density.
