FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MLHGFB#V0?

The R5F571MLHGFB#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiplier, and integrated single-precision IEEE-754 floating-point unit. The R5F571MLHGFB#V0 sustains this performance with zero-wait-state access to 256 KB of its 512 KB SRAM at full speed.

Does the R5F571MLHGFB#V0 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F571MLHGFB#V0 includes a dedicated IEEE 1588-compliant PTP controller (EPTPCa) tightly coupled to its dual Ethernet MACs. It provides hardware timestamping of ingress/egress frames with sub-microsecond resolution, supports PTP slave/master/boundary clock roles, and integrates with MTU3/GPT timers for precise event synchronization. This implementation is confirmed in the R01DS0249EJ0120 datasheet section 1.1 and Figure 1.1.

What package type and pin count does the R5F571MLHGFB#V0 use, and what are its key mechanical dimensions?

The R5F571MLHGFB#V0 uses a 177-pin TFLGA package (PTLG0177KA-A) measuring 8 mm × 8 mm with 0.5 mm pitch and 0.75 mm height. It features 127 general-purpose I/O pins with 5-V tolerance on 19 pins, open-drain capability on all outputs, and internal pull-up resistors. This compact, thermally efficient package is specified for –40°C to +105°C operation (G-version).

How many Ethernet and CAN interfaces does the R5F571MLHGFB#V0 integrate, and what standards do they comply with?

The R5F571MLHGFB#V0 integrates two fully independent Ethernet MAC controllers compliant with IEEE 802.3u (10/100 Mbps) and IEEE 1588-2008, plus three CAN modules compliant with ISO 11898-1 (standard and extended frames). Each CAN channel supports 32 mailboxes with configurable acceptance filtering. These interfaces are physically routed to dedicated pins on the 177-pin TFLGA package as documented in the R01DS0249EJ0120 pin listing.

What security and functional safety features are built into the R5F571MLHGFB#V0 for industrial applications?

The R5F571MLHGFB#V0 includes AES-128/192/256, DES/T-DES, and SHA-1/224/256 hardware accelerators; Trusted Memory blocks 8–9 for firmware protection; and a comprehensive IEC 60730 Class B self-test suite covering oscillator stoppage detection, CRC calculation, A/D converter diagnostics, and register write protection. These features are explicitly listed in the "Useful functions for IEC60730 compliance" section of the R01DS0249EJ0120 datasheet.
