For engineers reviewing the R5F571MJHDFP#30 datasheet, R5F571MJHDFP#30 pinout, R5F571MJHDFP#30 application, or R5F571MJHDFP#30 equivalent, this MCU delivers verified 240-MHz real-time execution, hardware-accelerated AES/SHA encryption, integrated PTP time-stamping for sub-microsecond synchronization, and IEC 60730 Class B compliance features including self-diagnostic A/D and oscillation-stop detection - critical for safety-certified motor drives and PLCs.

Technical Context

The R5F571MJHDFP#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 controllers (ETHERC) each with dedicated EDMAC channels and EPTPC blocks compliant with IEEE 1588-2008 for precise timestamping and master/slave clock synchronization in industrial Ethernet protocols.

Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, 512 KB SRAM (256 KB zero-wait at 240 MHz), and 32 KB ECCRAM with SEC-DED error correction. Clocking supports external crystal (8–24 MHz), internal HOCO/LOCO, and PLL multiplication - with independent domain clocks (ICLK up to 240 MHz, PCLKA up to 120 MHz, PCLKB up to 60 MHz) enabling optimized peripheral timing.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MJHDFP#30?

The R5F571MJHDFP#30 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, variable-length instruction set, and dual multiply-accumulate units - enabling deterministic execution of complex control algorithms in industrial motion applications without jitter.

Does the R5F571MJHDFP#30 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F571MJHDFP#30 includes dedicated EPTPC (PTP Controller for Ethernet) hardware blocks compliant with IEEE 1588-2008. Each of its two Ethernet MACs has an associated EPTPC that performs hardware timestamping of PTP frames with sub-100 ns resolution - eliminating software-induced latency in time-critical industrial Ethernet deployments like TSN-enabled servo networks.

How many A/D converter channels does the R5F571MJHDFP#30 provide, and what safety features do they include?

The R5F571MJHDFP#30 integrates two 12-bit A/D converter units: S12ADC0 with 8 channels and S12ADC1 with 21 channels, totaling 29 analog inputs. Both units support self-diagnostic functions, analog input disconnection detection, and programmable sample-and-hold - all certified for IEC 60730 Class B compliance to ensure reliable sensor monitoring in safety-critical industrial equipment.

What package type and pin count does the R5F571MJHDFP#30 use?

The R5F571MJHDFP#30 uses a 176-pin LFBGA package (PLQP0176KB-A), measuring 24 × 24 mm with 0.5 mm pitch. It provides 127 general-purpose I/O pins with 5-V tolerance, programmable pull-up resistors, and open-drain capability - optimized for industrial I/O expansion, isolation interface design, and mixed-signal board layout in harsh EMC environments.

Is hardware encryption available on the R5F571MJHDFP#30, and which algorithms are supported?

Yes, the R5F571MJHDFP#30 includes optional hardware-accelerated cryptographic engines supporting AES-128/192/256, DES/T-DES, SHA-1/224/256, and HMAC-160/224/256. These accelerators offload encryption/decryption and hash operations from the CPU - enabling secure boot verification, encrypted firmware updates, and TLS handshake acceleration in IIoT edge gateways without compromising real-time performance.
