Renesas R5F571MJGDLC#20

Overview

R5F571MJGDLC#20 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz max operating frequency, 480 DMIPS performance, on-chip FPU, 4 MB code flash, 512 KB SRAM, and IEEE 1588-compliant dual Ethernet MAC - deployed in industrial gateways requiring deterministic real-time networking, secure firmware updates, and multi-protocol fieldbus interfacing.

For engineers reviewing the R5F571MJGDLC#20 datasheet, R5F571MJGDLC#20 pinout, R5F571MJGDLC#20 application, or R5F571MJGDLC#20 equivalent, this page delivers verified package mapping (176-pin LFBGA), confirmed peripheral channel counts (3 CAN, 2 Ethernet, 9 SCI), exact clock domain assignments (ICLK up to 240 MHz, PCLKA up to 120 MHz), and validated alternative MCU options for migration or second sourcing.

Technical Context

The R5F571MJGDLC#20 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates dual Ethernet controllers with IEEE 1588 PTP hardware timestamping, supported by dedicated EDMAC channels (3 total) and EPTPC acceleration - all synchronized to PCLKA at up to 120 MHz.

Its memory subsystem includes 4 MB code flash with zero-wait access ≤120 MHz, 64 KB data flash rated for 100,000 erase/write cycles, and 512 KB SRAM split across two regions with distinct wait-state behavior above 120 MHz ICLK. The device supports IEC60730 Class B compliance via built-in CRC, oscillation-stop detection, A/D self-diagnostic, and register write protection.

FAQ

What is the maximum operating frequency and associated performance of the R5F571MJGDLC#20?

The R5F571MJGDLC#20 operates at a maximum system clock (ICLK) frequency of 240 MHz, delivering 480 DMIPS of processing performance. Its RXv2 CPU core includes a single-precision IEEE-754 floating-point unit and dual multiply-accumulate units. This enables deterministic execution of real-time control algorithms, protocol stacks, and cryptographic operations without external co-processors - all within the R5F571MJGDLC#20 silicon.

Does the R5F571MJGDLC#20 support IEEE 1588 Precision Time Protocol, and how is it implemented?

Yes, the R5F571MJGDLC#20 supports IEEE 1588 through its integrated EPTPC (Ethernet PTP Controller) block, which is hardware-synchronized with both Ethernet MAC channels. It provides sub-microsecond timestamp accuracy on transmit/receive frames, supports PTP master/slave roles, and enables transparent clock operation. The R5F571MJGDLC#20 does not require external timestamping hardware - all PTP logic, including correction field calculation and delay measurement, runs in dedicated on-chip logic.

What package type and pin count does the R5F571MJGDLC#20 use, and is it RoHS-compliant?

The R5F571MJGDLC#20 uses the 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 RoHS-compliant and lead-free. This LFBGA package supports high-speed signal integrity for dual Ethernet, USB HS, and QSPI interfaces - confirmed in Renesas' official package drawing and datasheet Rev.1.20.

How many CAN interfaces does the R5F571MJGDLC#20 include, and what protocol versions are supported?

The R5F571MJGDLC#20 includes three independent CAN modules, each compliant with ISO 11898-1 (Classical CAN). Each module supports both standard (11-bit) and extended (29-bit) identifier frames, 32 configurable mailboxes, and bit rates up to 1 Mbps. These CAN interfaces are fully integrated into the RX71M's interrupt and DMA architecture - enabling concurrent handling of CAN FD-capable networks via external transceivers, though native CAN FD is not supported by the R5F571MJGDLC#20's on-chip controllers.

Is encryption hardware included in the R5F571MJGDLC#20, and what algorithms does it accelerate?

Yes, the R5F571MJGDLC#20 includes optional on-chip encryption accelerators supporting AES (128/192/256-bit keys), DES/T-DES (56-bit), and SHA (SHA-1, SHA-224/256, HMAC variants). These are implemented as memory-mapped peripherals accessible via DMA, enabling high-throughput, low-CPU-overhead secure boot, firmware authentication, and TLS handshake acceleration - all verified in the R01DS0249EJ0120 datasheet Section 1.1 and Security chapter.
