Renesas R5F571MGHGFB#V0

Overview

R5F571MGHGFB#V0 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS with integrated single-precision IEEE-754 FPU, 4 MB on-chip code flash, 512 KB SRAM (including 32 KB ECC RAM), and IEEE 1588-compliant dual Ethernet MAC - designed for industrial real-time control, networked gateway, and secure edge node applications.

For engineers reviewing the R5F571MGHGFB#V0 datasheet, R5F571MGHGFB#V0 pinout, R5F571MGHGFB#V0 application, or R5F571MGHGFB#V0 equivalent, key selection criteria include its 177-pin TFLGA package, dual Ethernet + high-speed USB 2.0 + CAN triple interface concurrency, 240-MHz deterministic real-time performance, IEC60730 safety features, and hardware AES/SHA encryption support.

Technical Context

The R5F571MGHGFB#V0 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 DMA controllers (DMACa: 8 channels; EXDMACa: 2 channels) and a dedicated Ethernet DMA (EDMACa: 3 channels) to offload CPU bandwidth during high-throughput network transfers.

Its clock system supports simultaneous operation at multiple domains: ICLK up to 240 MHz for CPU execution, PCLKA up to 120 MHz for Ethernet/USB/AES peripherals, and PCLKB up to 60 MHz for timers/ADC/SCI - all derived from PLL-synthesized or HOCO/LOCO sources with independent division/multiplication settings.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MGHGFB#V0?

The R5F571MGHGFB#V0 operates at a maximum system clock frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) under benchmark conditions. This performance stems from its RXv2 CPU core with 5-stage pipeline, variable-length instruction set, and integrated 32-bit multiplier/divider - enabling deterministic execution for hard real-time industrial control tasks within the R5F571MGHGFB#V0's architecture.

Does the R5F571MGHGFB#V0 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MGHGFB#V0 includes a dedicated PTP controller (EPTPCa) tightly coupled to both Ethernet MAC modules, providing hardware timestamping for transmit and receive frames with sub-microsecond accuracy. This enables the R5F571MGHGFB#V0 to serve as a transparent clock or boundary clock in time-sensitive networking applications without CPU intervention.

What package type and pin count does the R5F571MGHGFB#V0 use?

The R5F571MGHGFB#V0 uses a 177-pin TFLGA (Thin Fine-Pitch Land Grid Array) package designated PTLG0177KA-A, measuring 8 mm × 8 mm with 0.5 mm pitch. It provides 127 general-purpose I/O pins, including 19 with 5-V tolerance, and supports industrial temperature range (–40°C to +105°C) as indicated by the 'G' suffix in R5F571MGHGFB#V0.

Which communication interfaces are available on the R5F571MGHGFB#V0?

The R5F571MGHGFB#V0 integrates dual IEEE 1588 Ethernet MACs, high-speed USB 2.0 (480 Mbps) with battery charging and OTG support, three CAN 2.0B modules (32 mailboxes each), nine SCI/SCIg channels, four SCIFA interfaces with 16-byte FIFOs, two I²C buses (up to 1 Mbps), two RSPI, one QSPI, SDHI, MMCIF, and SSI audio interfaces - all accessible concurrently in the R5F571MGHGFB#V0's 177-pin footprint.

Does the R5F571MGHGFB#V0 include hardware encryption capabilities?

Yes, the R5F571MGHGFB#V0 includes dedicated hardware accelerators for AES (128/192/256-bit), DES/T-DES, and SHA-1/224/256/HMAC cryptographic operations. These engines operate independently of the CPU, enabling secure boot, encrypted firmware updates, and TLS offloading - a core requirement for IEC60730 Class B certification and edge security in the R5F571MGHGFB#V0's target applications.
