Product details
Overview
R5F571MLCDLC#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-performance control and connectivity hub in industrial Ethernet gateways requiring IEEE 1588 time synchronization, USB 2.0 HS with battery charging, and CAN FD-capable communication.
For engineers reviewing the R5F571MLCDLC#20 datasheet, R5F571MLCDLC#20 pinout, R5F571MLCDLC#20 application, or R5F571MLCDLC#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet MAC with PTP support, 3-channel CAN, and hardware AES/SHA encryption - all validated for IEC 60730 Class B compliance in safety-critical embedded systems.
Technical Context
The R5F571MLCDLC#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for deterministic real-time execution. Its clock system combines external crystal oscillation (8–24 MHz), internal HOCO (16/18/20 MHz), and PLL to generate independent clocks: ICLK up to 240 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals.
It integrates three DMA controllers - DMAC (8 ch), EXDMAC (2 ch), and EDMAC (3 ch for Ethernet) - enabling zero-CPU-load frame transfers. The ELC (Event Link Controller) supports 119 internal event signals for hardware-triggered peripheral coordination, eliminating software interrupt latency in time-critical control loops like motor PWM generation and A/D capture triggering.

What is the maximum operating frequency and DMIPS rating of the R5F571MLCDLC#20?
The R5F571MLCDLC#20 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-bit multiply, and dual MAC units - enabling real-time processing of complex control algorithms and protocol stacks without external acceleration. The R5F571MLCDLC#20 maintains this performance across its full temperature range (–40°C to +85°C) with verified timing closure.
Does the R5F571MLCDLC#20 support IEEE 1588 Precision Time Protocol hardware acceleration?
Yes, the R5F571MLCDLC#20 integrates a dedicated EPTPC (Ethernet PTP Controller) block compliant with IEEE 1588-2008. It performs hardware timestamping of Ethernet frames at the MAC layer with sub-microsecond accuracy, supports Pdelay_Req/Pdelay_Resp message handling, and synchronizes internal timers to master clocks - eliminating software-induced jitter. This capability is validated in the R01DS0249EJ0120 datasheet and enables deterministic time synchronization in industrial automation networks.
What package type and pin count does the R5F571MLCDLC#20 use?
The R5F571MLCDLC#20 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array measuring 24 × 24 mm with 0.5 mm pitch. This package provides 127 general-purpose I/O pins (19 of which are 5-V tolerant), dedicated Ethernet MII/MDIO, USB 2.0 HS differential pairs, and CAN transceiver interfaces - all mapped to validated land patterns in Renesas reference designs. The package is RoHS-compliant and moisture sensitivity level 3.
How many A/D converter channels does the R5F571MLCDLC#20 include, and what resolutions are supported?
The R5F571MLCDLC#20 integrates two independent 12-bit S12ADC units: Unit 0 with 8 channels and Unit 1 with 21 channels, totaling 29 analog inputs. Each unit supports selectable resolution of 8, 10, or 12 bits. Conversion times are 0.42 µs (8-bit), 0.45 µs (10-bit), and 0.48 µs (12-bit) per channel. Both units feature sample-and-hold circuits, self-diagnostic functions, and digital comparison logic - confirmed in Section 1.1 of the R01DS0249EJ0120 datasheet.
Is hardware encryption available on the R5F571MLCDLC#20, and which algorithms are supported?
Yes, the R5F571MLCDLC#20 includes optional on-chip cryptographic accelerators supporting AES (128/192/256-bit keys), DES/T-DES, and SHA (SHA-1, SHA-224, SHA-256, HMAC variants). These modules operate independently of the CPU, enabling secure boot, firmware signing, and encrypted data logging without performance penalty.
