Renesas R5F571MLCDFC#V0

Overview

R5F571MLCDFC#V0 from Renesas is a 32-bit RXv2 microcontroller designed for high-performance industrial and networked embedded systems. It operates at up to 240 MHz (480 DMIPS), integrates 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN, SD host interface, and hardware AES/SHA encryption - enabling real-time control in smart grid gateways and industrial IoT edge nodes.

For engineers reviewing the R5F571MLCDFC#V0 datasheet, R5F571MLCDFC#V0 pinout, R5F571MLCDFC#V0 application, or R5F571MLCDFC#V0 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB HS + CAN triple-protocol connectivity, 240-MHz deterministic real-time execution, and IEC60730 safety support for certified industrial firmware deployments.

Technical Context

The R5F571MLCDFC#V0 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - delivering 480 DMIPS at 240 MHz while supporting little-endian or big-endian data arrangement. Its memory subsystem includes 4 MB code flash (0-wait ≤120 MHz), 64 KB data flash (100k write cycles), 512 KB SRAM (with 32 KB ECCRAM), and 8 KB standby RAM backed by VBATT.

Peripherals are clocked across four domains: ICLK (up to 240 MHz for CPU), PCLKA (up to 120 MHz for ETHERC/USBA/AES), PCLKB (up to 60 MHz for timers/SCI/USBb), and PCLKC/PCLKD (60 MHz for dual 12-bit ADC units). Dual Ethernet MACs use dedicated EDMAC (3-channel) and EPTPC (IEEE 1588 PTP) blocks, while USBAa supports high-speed USB 2.0 (480 Mbps) only on 176-/177-pin variants like this part.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MLCDFC#V0?

The R5F571MLCDFC#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved using the RXv2 CPU core with 5-stage pipeline, single-cycle 32-bit multiplier, and IEEE-754 floating-point unit. The R5F571MLCDFC#V0 maintains deterministic execution even under interrupt load, making it suitable for hard real-time industrial control tasks where cycle predictability is essential.

Does the R5F571MLCDFC#V0 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MLCDFC#V0 includes a dedicated PTP controller (EPTPCa) tightly coupled to both Ethernet MACs, enabling full IEEE 1588-2008 (v2) hardware timestamping with sub-microsecond accuracy. The R5F571MLCDFC#V0 supports one-step and two-step clock correction, transparent clock operation, and hardware-assisted delay measurement - critical for time-sensitive networking in substation automation and synchronized motion control.

What package type and pin count does the R5F571MLCDFC#V0 use?

The R5F571MLCDFC#V0 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm pitch. It is rated for –40°C to +85°C (D-version) and features 127 general-purpose I/O pins, including 19 with 5-V tolerance and configurable pull-up/open-drain. This package matches the full peripheral complement of the RX71M Group, including dual Ethernet and high-speed USB.

How much on-chip flash and RAM does the R5F571MLCDFC#V0 integrate?

The R5F571MLCDFC#V0 integrates 4 MB of on-chip code flash memory (0-wait-state access up to 120 MHz), 64 KB of reprogrammable data flash (rated for 100,000 write/erase cycles), 512 KB of SRAM (with 256 KB accessible at full 240 MHz speed), 32 KB of ECC-protected RAM, and 8 KB of VBATT-backed standby RAM. This memory hierarchy supports complex real-time OS, secure boot, firmware updates, and data logging without external memory.

Is hardware encryption available on the R5F571MLCDFC#V0?

Yes, the R5F571MLCDFC#V0 offers optional hardware-accelerated cryptography including AES-128/192/256, DES/T-DES, SHA-1/224/256, and HMAC. These engines operate independently of the CPU, enabling secure boot, TLS offload, and encrypted firmware updates with minimal latency impact. The R5F571MLCDFC#V0 also includes a unique 12-byte device ID and trusted memory protection for blocks 8 and 9 of code flash - meeting foundational requirements for IEC62443 and FDA cybersecurity guidance.
