Product details
Overview
R5F571MJCDLC#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 IEEE 1588-compliant dual Ethernet MAC - designed for industrial real-time control, networked gateway, and secure edge node applications.
For engineers reviewing the R5F571MJCDLC#20 datasheet, R5F571MJCDLC#20 pinout, R5F571MJCDLC#20 application, or R5F571MJCDLC#20 equivalent, key selection considerations include its 176-pin LFBGA package (PLQP0176KB-A), dual Ethernet + USB HS + CAN triple interface concurrency, 240-MHz deterministic real-time execution, and IEC60730-ready safety features including CRC, IWDTa, and A/D self-diagnostic.
Technical Context
The R5F571MJCDLC#20 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) - enabling ultra-compact code and deterministic interrupt latency down to 5 CPU cycles. Its clock system supports independent domain scaling: 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.
Real-time data movement is managed via three dedicated DMA subsystems: 8-channel DMAC, 2-channel EXDMAC, and 3-channel EDMAC (for Ethernet), each supporting descriptor-based transfers and event-linking via ELC - eliminating CPU overhead for time-critical peripheral handshaking such as A/D trigger synchronization, PWM dead-time compensation, and RTC time-capture on external events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLCDLC#20 | Same RX71M family, identical 176-pin LFBGA package and core specs, but with 2.5 MB code flash instead of 4 MB. | Suitable for firmware images <2.5 MB where full 4 MB is unused; retains all peripherals including dual Ethernet and USB HS. | Select when application firmware size is confirmed ≤2.5 MB and cost optimization is prioritized over future scalability. |
| R5F572MLHDFP#30 | Higher-pin-count RX72M variant (216-pin LQFP), 240 MHz CPU, 4 MB flash, but adds 2D graphics accelerator and enhanced USB HS host stack. | Better suited for HMI-rich applications (touch GUI, video overlay); lacks IEEE 1588 PTP engine and has only single Ethernet MAC. | Choose only if display rendering or USB peripheral enumeration complexity outweighs need for dual synchronized Ethernet. |
Compared with R5F571MJCDLC#20, the R5F571MLCDLC#20 offers identical real-time performance and interface concurrency at lower flash capacity - ideal for cost-sensitive deployments with stable firmware footprints; the R5F572MLHDFP#30 trades dual IEEE 1588 Ethernet for graphics acceleration and larger package - making it unsuitable for time-synchronized industrial networking but advantageous for embedded HMI endpoints.

How many Ethernet MAC channels does the R5F571MJCDLC#20 include?
The R5F571MJCDLC#20 includes two fully independent IEEE 802.3-compliant Ethernet MAC channels, each supporting 10/100 Mbps operation in full- or half-duplex mode with MII or RMII physical layer interfaces. This dual-MAC capability is exclusive to 176- and 177-pin RX71M variants and is essential for R5F571MJCDLC#20's role in redundant network gateways and time-synchronized packet forwarding applications.
