For engineers reviewing the R5F571MJGDFB#30 datasheet, R5F571MJGDFB#30 pinout, R5F571MJGDFB#30 application, or R5F571MJGDFB#30 equivalent, key selection criteria include IEEE 1588 timestamping accuracy, dual Ethernet channel isolation, 240-MHz real-time interrupt latency, and hardware AES/SHA acceleration for secure boot and OTA updates.

Technical Context

The R5F571MJGDFB#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions - enabling ultra-compact code density and deterministic 1-cycle 32×32 multiply execution. It integrates dual independent Ethernet controllers (ETHERC) each with dedicated EDMAC channels and EPTPC blocks compliant with IEEE 1588-2008 for hardware timestamping and PTP slave/master operation.

Its clock system supports simultaneous domain partitioning: ICLK up to 240 MHz for CPU/SRAM, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals - enabling precise timing isolation for time-critical control loops and network stacks without software overhead.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MJGDFB#30?

The R5F571MJGDFB#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, single-cycle 32×32 multiply, and Harvard architecture. The R5F571MJGDFB#30 sustains this performance across full temperature range (–40°C to +105°C) with appropriate thermal design and power supply decoupling.

Does the R5F571MJGDFB#30 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F571MJGDFB#30 includes two dedicated EPTPC (Ethernet PTP Controller) modules, one per Ethernet MAC, compliant with IEEE 1588-2008. Each EPTPC provides hardware timestamping with sub-microsecond resolution on transmit and receive frames - eliminating software-induced jitter and enabling precise master/slave synchronization in industrial time-sensitive networks.

What are the flash and SRAM capacities of the R5F571MJGDFB#30?

The R5F571MJGDFB#30 integrates 4 MB of on-chip code flash memory and 512 KB of SRAM. The flash supports background programming/erasing (BGO), enabling firmware updates without halting execution. Of the SRAM, 256 KB (0000_0000h–0003_FFFFh) offers no-wait access at 240 MHz; the remaining 256 KB (0004_0000h–0007_FFFFh) requires one wait state above 120 MHz. Additionally, it includes 32 KB ECCRAM and 8 KB standby RAM.

Which package type and pin count does the R5F571MJGDFB#30 use?

The R5F571MJGDFB#30 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array (LFBGA) with 24 mm × 24 mm body size and 0.5 mm ball pitch. It provides 127 general-purpose I/O pins, including 19 with 5-V tolerance, programmable pull-up resistors, and open-drain capability - optimized for industrial interface bridging and high-density PCB layouts.

Does the R5F571MJGDFB#30 include hardware cryptographic acceleration?

Yes, the R5F571MJGDFB#30 includes a dedicated hardware crypto engine supporting AES (128/192/256-bit keys), DES/TDES, SHA-1/224/256, and HMAC. These accelerators operate independently of the CPU, enabling fast secure boot verification, TLS handshake offload, and encrypted firmware storage - reducing cryptographic latency by >90% compared to software-only implementations on the R5F571MJGDFB#30.
