Product details
Overview
R5F571MLHDLC#20 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz (480 DMIPS), featuring 4 MB on-chip code flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and dual 12-bit A/D converters (8 + 21 channels). It targets industrial automation controllers requiring real-time deterministic I/O, secure firmware updates, and time-synchronized networked sensing.
For engineers reviewing the R5F571MLHDLC#20 datasheet, R5F571MLHDLC#20 pinout, R5F571MLHDLC#20 application, or R5F571MLHDLC#20 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), functional pin roles, real-world use cases in time-critical industrial networking, and two validated alternative MCUs with documented interface and memory trade-offs.
Technical Context
The R5F571MLHDLC#20 implements the RXv2 CPU core with single-precision IEEE-754 FPU, dual multiply-accumulate units, and memory protection unit (MPU) for safety-critical execution. Its clock architecture supports independent domain 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/ADC.
It integrates dual Ethernet MACs with IEEE 1588 PTP hardware timestamping, EPTPC controller, and 3-channel EDMAC - enabling precise time synchronization and low-CPU-load frame handling. The device includes two CAN modules (32 mailboxes each), 9 SCI interfaces (with LIN/Smart Card support), and dual 12-bit S12ADC units with self-diagnostic capability and channel-specific sampling control.

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 |
|---|---|---|---|
| R5F571MLHDFP#30 | Same RX71M core, identical peripherals, but in 176-pin LFQFP (PLQP0176KB-A footprint variant) | No change in functionality; differs only in package mechanicals (QFP vs BGA), affecting PCB assembly and thermal performance | Select for through-hole prototyping or where BGA rework is unavailable; same pinout but different soldering process and thermal resistance |
| R5F566TEADFP#30 | RX66T core (200 MHz), 2 MB flash, single Ethernet MAC, no IEEE 1588, no high-speed USB, 128-pin LFQFP | Limited networking capability; suitable for cost-sensitive servo drives without time-synchronized multi-node coordination | Choose when dual Ethernet + PTP is unnecessary and lower BOM cost outweighs reduced feature headroom |
Compared with R5F571MLHDLC#20, R5F571MLHDFP#30 offers identical electrical and functional behavior in an alternate package, while R5F566TEADFP#30 trades dual PTP Ethernet and crypto acceleration for lower price and smaller footprint - making it viable only where those features are unused.
