FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MJHGFP#V0?

The R5F571MJHGFP#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved through its optimized RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiplier, and integrated single-precision IEEE-754 floating-point unit. The R5F571MJHGFP#V0 maintains this performance across its full temperature range (–40°C to +105°C) with appropriate thermal design.

Does the R5F571MJHGFP#V0 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F571MJHGFP#V0 includes a dedicated IEEE 1588-compliant PTP controller (EPTPCa) tightly coupled to both Ethernet MACs. It provides hardware timestamping of ingress/egress Ethernet frames with nanosecond resolution, supports PTP slave/master/transparent clock roles, and enables sub-microsecond synchronization accuracy in industrial control networks. The R5F571MJHGFP#V0 does not require external timestamping hardware.

What are the memory configuration options for the R5F571MJHGFP#V0, and how is data flash endurance specified?

The R5F571MJHGFP#V0 integrates 4 MB of on-chip code flash memory and 64 KB of reprogrammable data flash memory rated for 100,000 write/erase cycles. Code flash supports background programming/erasing (BGO) and trusted memory protection for blocks 8–9. Data flash is organized as a single 64 KB sector with uniform endurance across all addresses. The R5F571MJHGFP#V0 also includes 512 KB of SRAM (with 32 KB ECC-protected section) and 8 KB of battery-backed standby RAM.

Which communication interfaces are supported by the R5F571MJHGFP#V0 for industrial networking?

The R5F571MJHGFP#V0 supports dual IEEE 802.3 10/100 Mbps Ethernet MACs with MII/RMII interfaces, three ISO 11898-1 CAN v2.0B channels (32 mailboxes each), high-speed USB 2.0 host/function with battery charging (480 Mbps), and optional SD host interface. It also includes nine serial channels (SCIg/SCIh), four SCIFA interfaces with 16-byte FIFOs, two I²C buses (up to 1 Mbps), and quad SPI-all accessible simultaneously without resource conflict. The R5F571MJHGFP#V0 is engineered for multi-protocol industrial gateways.

How does the R5F571MJHGFP#V0 support functional safety standards like IEC60730?

The R5F571MJHGFP#V0 includes hardware features required for IEC60730 Class B compliance: oscillation-stop detection, hardware CRC calculator, windowed independent watchdog timer (IWDTa), A/D converter self-diagnostic function, register write protection, and memory protection unit (MPU). These capabilities enable runtime verification of clock integrity, memory contents, and peripheral operation-reducing software validation burden. The R5F571MJHGFP#V0 documentation provides detailed guidance for implementing these features in certified applications.
