It targets industrial automation controllers requiring real-time deterministic I/O, secure connectivity, and functional safety support per IEC 60730.
For engineers reviewing the R5F571MGHDLK#20 datasheet, R5F571MGHDLK#20 pinout, R5F571MGHDLK#20 application, or R5F571MGHDLK#20 equivalent, this MCU delivers verified 240-MHz deterministic execution, dual Ethernet with hardware timestamping, integrated AES/SHA crypto engines, and full-featured low-power modes - all in a 176-pin LFBGA package with 127 GPIOs and 5-V-tolerant inputs.
Technical Context
The R5F571MGHDLK#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual independent DMA controllers (DMACa: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) for zero-copy frame handling across two 10/100 Mbps Ethernet interfaces.
Its clock system supports simultaneous operation at multiple frequencies: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES peripherals, and PCLKB up to 60 MHz for timers, ADC, and serial interfaces. The device includes a memory protection unit (MPU), trusted memory (TM) blocks 8–9, and register write protection for IEC 60730 compliance.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MGHDLK#20?
The R5F571MGHDLK#20 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved through the RXv2 CPU core's 5-stage pipeline, variable-length instruction set, and dual multiply-accumulate units. The R5F571MGHDLK#20 sustains this performance with zero wait states on code flash up to 120 MHz and efficient cache-like access via the AFU (Access Frequency Unit) even at full 240 MHz.
Does the R5F571MGHDLK#20 support IEEE 1588 Precision Time Protocol?
Yes, the R5F571MGHDLK#20 integrates a dedicated PTP controller (EPTPCa) compliant with IEEE 1588-2008, tightly coupled to both Ethernet MACs. It provides hardware timestamping for ingress/egress frames with sub-microsecond accuracy, enabling master/slave clock synchronization in industrial motion control and power substation automation. The R5F571MGHDLK#20 supports one-step and two-step timestamping modes and PTP event message filtering.
What USB capabilities does the R5F571MGHDLK#20 include?
The R5F571MGHDLK#20 includes two USB modules: USBAa (high-speed USB 2.0 host/function with battery charging v1.2 support) and USBb (full-speed USB 2.0 host/function/OTG). USBAa supports 480 Mbps transfer, BC1.2 detection (SDP/CDP/DCP), and integrated 8.5 KB RAM buffer - eliminating need for external transceivers. This capability is exclusive to 176-/177-pin RX71M variants like the R5F571MGHDLK#20.
How many Ethernet MAC interfaces does the R5F571MGHDLK#20 have, and what standards do they support?
The R5F571MGHDLK#20 integrates two independent Ethernet MAC controllers (ETHERC), each supporting 10/100 Mbps operation in full- and half-duplex modes per IEEE 802.3. Both support MII and RMII physical layer interfaces, IEEE 802.3x flow control, Magic Packet™ wake-on-LAN, and multicast frame filtering. Each MAC connects to a dedicated EDMACa channel and shares the EPTPCa for IEEE 1588 timestamping - a capability confirmed for the R5F571MGHDLK#20 in the RX71M datasheet Rev.1.20.
What is the flash and RAM configuration of the R5F571MGHDLK#20?
The R5F571MGHDLK#20 includes 4 MB of on-chip code flash memory with background programming/erasing (BGO), 64 KB of reprogrammable data flash (100,000 write cycles), 512 KB of general-purpose SRAM (with 256 KB accessible at zero wait states even at 240 MHz), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. This memory hierarchy is fully documented for the R5F571MGHDLK#20 in Table 1.1 of R01DS0249EJ0120.
