Product details
Overview
R5F571MFCDLC#20 from Renesas is a 32-bit RXv2 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 dual 12-bit A/D converters (8 + 21 channels). It serves as a high-integration control and connectivity hub in industrial Ethernet gateways requiring IEEE 1588 time synchronization, CAN bus interfacing, and USB 2.0 HS host functionality.
For engineers reviewing the R5F571MFCDLC#20 datasheet, R5F571MFCDLC#20 pinout, R5F571MFCDLC#20 application, or R5F571MFCDLC#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC support, 3-channel CAN with 32 mailboxes per channel, and hardware-accelerated AES/SHA encryption - all critical for deterministic real-time control and secure edge node design.
Technical Context
The R5F571MFCDLC#20 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. Its clock system supports independent domain scaling: 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, ADCs, and serial interfaces.
Real-time determinism is reinforced by the Event Link Controller (ELC) enabling 119 internal event signals to trigger timer operations, A/D conversions, or GPIO state changes without CPU intervention. The device integrates three DMA controllers - DMACA (8 channels), EXDMAC (2 channels), and EDMAC (3 channels dedicated to Ethernet) - to offload data movement from the CPU during high-throughput communication tasks.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLCDLC#20 | Same RX71M group, identical 176-pin LFBGA package, but with 2.5 MB code flash instead of 4 MB | Suitable where firmware footprint is <2.5 MB and cost optimization is prioritized over future scalability | Select when flash headroom is not required and BOM cost reduction is critical |
| R5F571MFDLC#20 | Same 4 MB flash and peripherals, but in 144-pin LFQFP (PLQP0144KA-A) instead of 176-pin LFBGA | Better suited for space-constrained PCBs where BGA assembly is undesirable or unavailable | Choose for prototyping or low-volume production avoiding BGA reflow complexity |

The R5F571MFCDLC#20 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, single-cycle 32-bit multiplier, and optimized instruction set - enabling fast interrupt response and real-time deterministic execution critical for industrial control loops. The R5F571MFCDLC#20 sustains this throughput while running full peripheral stacks including dual Ethernet and USB 2.0 HS.
Does the R5F571MFCDLC#20 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MFCDLC#20 includes a dedicated PTP controller (EPTPCa) tightly integrated with its dual Ethernet MAC (ETHERC) modules. This hardware block performs frame-level timestamping with sub-100 ns resolution, supports PTP master/slave roles, and enables transparent clock and boundary clock operation per IEEE 1588-2008. The R5F571MFCDLC#20 uses this capability to synchronize distributed I/O nodes in time-sensitive networking applications without external timestamping ICs.
How many CAN channels does the R5F571MFCDLC#20 support, and what is the mailbox depth per channel?
The R5F571MFCDLC#20 integrates three independent CAN modules (CAN0–CAN2), each compliant with ISO 11898-1 and supporting standard and extended frames. Each channel provides 32 dedicated message mailboxes for flexible transmit/receive buffering and priority-based arbitration. This configuration allows the R5F571MFCDLC#20 to serve as a central CAN gateway connecting multiple vehicle or machinery subnetworks while maintaining deterministic latency and error handling.
What package type and pin count does the R5F571MFCDLC#20 use, and is it RoHS-compliant?
The R5F571MFCDLC#20 is housed in a PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 mm × 24 mm with 0.5 mm ball pitch. It is fully RoHS-compliant and qualified for lead-free solder reflow profiles. This package provides optimal thermal dissipation and signal integrity for high-speed interfaces like Ethernet MII and USB 2.0 HS - making the R5F571MFCDLC#20 suitable for dense industrial PCB layouts requiring reliable high-bandwidth communication.
Does the R5F571MFCDLC#20 include hardware encryption accelerators, and which algorithms are supported?
Yes, the R5F571MFCDLC#20 includes optional hardware cryptographic accelerators supporting AES (128/192/256-bit keys), DES and triple-DES (T-DES), and SHA-1/SHA-224/SHA-256/HMAC hash functions. These modules operate independently of the CPU, enabling secure boot, firmware authentication, and encrypted data logging without degrading real-time performance. The R5F571MFCDLC#20 leverages this capability to meet IEC 62443 security requirements in industrial IoT edge devices.
