Overview
R5F571MLHDBG#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 (including 32 KB ECC RAM), IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, CAN v2.0B (3 channels), and dual 12-bit A/D converters - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F571MLHDBG#20 datasheet, R5F571MLHDBG#20 pinout, R5F571MLHDBG#20 application, or R5F571MLHDBG#20 equivalent, key selection criteria include its 177-pin TFLGA package (8 × 8 mm, 0.5-mm pitch), dual Ethernet + USB HS + CAN coexistence, 240-MHz real-time execution, IEC60730 safety support, and hardware AES/SHA encryption for secure firmware updates and data-in-transit protection.
Technical Context
The R5F571MLHDBG#20 implements the RXv2 CPU core with single-cycle 32×32 multiplier, IEEE-754 single-precision FPU, and memory protection unit (MPU). It supports little-endian or big-endian data arrangement and executes 75 base instructions plus 11 FPU and 23 DSP extensions.
Clock architecture includes independent domain clocks: ICLK up to 240 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, PCLKB up to 60 MHz for timers/peripherals, and dedicated ADCLKs for two S12AD units. Its ELC (Event Link Controller) enables 119 internal event interlinks without CPU intervention - critical for low-latency sensor-to-actuator response in motion control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F571MLHDBV#20 | Same die, 176-pin LFBGA (13 × 13 mm, 0.8-mm pitch); identical peripherals and specs except reduced GPIO count (127 → 124) and no PDC | Lacks Parallel Data Capture Unit; unsuitable for CMOS camera interface applications | Select when board space permits larger pitch and camera interface is unnecessary; offers same thermal performance with easier reworkability |
| R5F571MNHDBG#20 | Same 177-pin TFLGA package but with 2 MB flash (vs. 4 MB); otherwise identical clocking, peripherals, security, and timing features | Insufficient code space for complex protocol stacks (e.g., full PROFINET IRT + TLS + web server) | Choose for cost-sensitive designs where application firmware fits within 2 MB and future feature expansion is not required |
Compared with R5F571MLHDBG#20, the R5F571MLHDBV#20 trades PDC and fine-pitch packaging for mechanical robustness and rework ease, while R5F571MNHDBG#20 reduces flash capacity to lower BOM cost - neither offers pin-to-pin compatibility nor identical peripheral set, making R5F571MLHDBG#20 the only option for full-featured, space-constrained, camera-integrated industrial gateways.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MLHDBG#20?
The R5F571MLHDBG#20 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS (Dhrystone MIPS) performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32×32 multiplier, and optimized instruction set - enabling hard real-time loop execution in motion control and industrial networking applications where deterministic timing is critical. The R5F571MLHDBG#20 sustains this performance across its full temperature range (–40°C to +105°C).
Does the R5F571MLHDBG#20 support IEEE 1588 Precision Time Protocol (PTP)?
Yes, the R5F571MLHDBG#20 integrates a dedicated EPTPCa (PTP Controller for Ethernet) block compliant with IEEE 1588-2008. It provides hardware timestamping with sub-100 ns resolution, transparent clock correction, and support for delay request-response and peer delay mechanisms - enabling sub-microsecond synchronization across distributed industrial Ethernet nodes without CPU overhead. This capability is active on both of its Ethernet MAC channels.
What are the flash and RAM configurations of the R5F571MLHDBG#20?
The R5F571MLHDBG#20 includes 4 MB of on-chip code flash memory (with background programming/erasing), 512 KB of general-purpose SRAM (256 KB accessible at full 240 MHz speed), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. These resources support complex protocol stacks, real-time OS operation, and secure firmware update storage - all without external memory, reducing bill-of-materials and PCB area. The R5F571MLHDBG#20 uses these memory blocks concurrently during full-load operation.
Which communication interfaces does the R5F571MLHDBG#20 support for industrial connectivity?
The R5F571MLHDBG#20 supports dual IEEE 1588 Ethernet MAC, high-speed USB 2.0 with battery charging (BC1.2), three CAN 2.0B channels (32 mailboxes each), nine SCI/SCIg/SCIh serial ports, four SCIFA interfaces with 16-byte FIFOs, two I²C buses (up to 1 Mbps), quad SPI, SD host interface, MMCIF, and parallel data capture (PDC). This enables native integration of legacy fieldbuses, modern industrial Ethernet, and secure cloud uplinks - all within a single R5F571MLHDBG#20 device.
Is the R5F571MLHDBG#20 qualified for functional safety standards like IEC60730?
Yes, the R5F571MLHDBG#20 includes multiple hardware features for IEC60730 Class B compliance: oscillation-stoppage detection, built-in CRC calculation unit, independent watchdog timer (IWDTa) with configurable windowing, self-diagnostic A/D converter test, analog input disconnection detection, and register write protection. These capabilities are documented in Renesas' Functional Safety Manual (R01UM0474EJ0100) and reduce external component count for household appliance, HVAC, and motor control certifications.
