FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MLGGFP#V0?

The R5F571MLGGFP#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 32×32 multiplier, and efficient instruction set - enabling real-time control tasks such as multi-axis motion profiling and closed-loop servo regulation without external co-processors.

Does the R5F571MLGGFP#V0 support IEEE 1588 Precision Time Protocol hardware timestamping?

Yes, the R5F571MLGGFP#V0 integrates the EPTPC (PTP Controller for Ethernet) module, which provides hardware-accelerated IEEE 1588 timestamping for both transmit and receive Ethernet frames. This enables sub-microsecond time synchronization accuracy essential for industrial TSN applications, and eliminates software-based timestamp overhead that introduces jitter in the R5F571MLGGFP#V0's dual Ethernet implementation.

What are the flash and RAM capacities of the R5F571MLGGFP#V0?

The R5F571MLGGFP#V0 includes 4 MB of on-chip code flash memory (with background programming/erasing), 64 KB of reprogrammable data flash (rated for 100,000 erase cycles), 512 KB of general-purpose SRAM (256 KB accessible with zero wait states at 240 MHz), 32 KB of ECC-protected RAM, and 8 KB of battery-backed standby RAM - providing robust memory architecture for complex industrial firmware, secure boot, and non-volatile data logging in the R5F571MLGGFP#V0.

Which communication interfaces are supported by the R5F571MLGGFP#V0 for industrial networking?

The R5F571MLGGFP#V0 supports dual IEEE 1588-compliant Ethernet MACs, three CAN 2.0B modules (32 mailboxes each), nine SCI channels, four SCIFA interfaces with 16-byte FIFOs, two I2C buses (up to 1 Mbps), QSPI, SDHI, and MMCIF. This comprehensive suite enables simultaneous fieldbus (CAN), industrial Ethernet (EtherNet/IP, PROFINET), and storage/upgrade (SD/USB) connectivity - all managed concurrently in the R5F571MLGGFP#V0's multi-clock domain architecture.

Is the R5F571MLGGFP#V0 qualified for extended temperature operation?

Yes, the R5F571MLGGFP#V0 is rated for operation from –40°C to +105°C (G-grade), validated across its full specification range including flash programming, Ethernet PHY interface timing, and analog peripheral accuracy. This makes it suitable for deployment in harsh environments such as factory-floor PLCs, outdoor energy gateways, and transportation infrastructure - where thermal stability is critical for the R5F571MLGGFP#V0's long-term reliability.
