Overview
R5F571MJCGFP#V0 from Renesas is a 32-bit RXv2 microcontroller with 240 MHz CPU, 4 MB on-chip flash, 512 KB SRAM, IEEE 1588-compliant dual Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring deterministic real-time control, secure firmware updates, and multi-protocol connectivity.
For engineers reviewing the R5F571MJCGFP#V0 datasheet, R5F571MJCGFP#V0 pinout, R5F571MJCGFP#V0 application, or R5F571MJCGFP#V0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA), confirmed peripheral channel counts for Ethernet/USB/CAN, and two validated alternative MCUs with documented functional trade-offs.
Technical Context
The R5F571MJCGFP#V0 implements the RXv2 core with single-cycle 32×32-bit multiply, IEEE-754 FPU, and memory protection unit (MPU), operating at up to 240 MHz with 480 DMIPS performance. Its clock system integrates PLL, HOCO/LOCO oscillators, and independent PCLK domains (PCLKA up to 120 MHz for Ethernet/USB/AES; PCLKB up to 60 MHz for timers/ADC).
It features dual Ethernet controllers with integrated IEEE 1588 PTP hardware, three CAN modules (32 mailboxes each), and a dedicated EXDMAC with cluster transfer mode - enabling time-synchronized packet timestamping, concurrent CAN/Ethernet bridging, and deterministic I/O processing without CPU intervention.

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 |
|---|---|---|---|
| R5F571MLDFP#V0 | Same RX71M group, identical 176-pin LFBGA package, but 2.5 MB flash and 384 KB SRAM | Limited firmware image size and reduced buffer space for multi-protocol stacks | Select when application firmware fits within 2.5 MB and requires lower BOM cost without sacrificing pin compatibility |
| R5F566TEADFP#30 | RX66T group, 160 MHz CPU, 1 MB flash, 192 KB SRAM, single Ethernet, no IEEE 1588, no high-speed USB | No hardware PTP timestamping; insufficient RAM for dual-protocol gateway buffering | Choose for cost-sensitive motor control where CAN + single Ethernet suffices and sub-µs time sync is unnecessary |

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MJCGFP#V0?
The R5F571MJCGFP#V0 operates at a maximum frequency of 240 MHz and delivers 480 DMIPS performance. This is achieved through its RXv2 CPU core with 5-stage pipeline, single-cycle 32×32-bit multiply, and efficient instruction set. The R5F571MJCGFP#V0 sustains this performance with zero wait states for code fetch up to 120 MHz and one wait state above that threshold, ensuring deterministic execution in real-time control loops.
Does the R5F571MJCGFP#V0 support IEEE 1588 Precision Time Protocol hardware timestamping?
Yes, the R5F571MJCGFP#V0 integrates a dedicated IEEE 1588-compliant PTP controller (EPTPCa) linked directly to both Ethernet MACs. It provides hardware timestamp insertion and extraction with sub-microsecond resolution, independent of CPU load. The R5F571MJCGFP#V0 uses this capability to synchronize distributed I/O across industrial networks without requiring external timing ICs or software-based corrections.
How many CAN modules does the R5F571MJCGFP#V0 include, and what is their mailbox capacity?
The R5F571MJCGFP#V0 includes three fully compliant ISO 11898-1 CAN modules, each supporting 32 configurable mailboxes with individual acceptance filtering and FIFO buffering. This enables concurrent handling of multiple CAN networks - such as drive train, body control, and diagnostics - without CPU polling. The R5F571MJCGFP#V0's CAN modules operate up to 1 Mbps and integrate automatic retransmission and error confinement per ISO standard.
What encryption algorithms are supported by the R5F571MJCGFP#V0's optional security engine?
The R5F571MJCGFP#V0's optional hardware encryption engine supports AES with 128-, 192-, and 256-bit keys; DES and triple-DES (T-DES); and SHA-1, SHA-224, SHA-256, and HMAC variants. These accelerators offload cryptographic operations from the CPU, enabling secure boot verification, encrypted firmware updates, and TLS handshake acceleration. The R5F571MJCGFP#V0 also includes Trusted Memory protection for flash blocks 8 and 9 to prevent unauthorized readout.
What is the package type and pin count of the R5F571MJCGFP#V0?
The R5F571MJCGFP#V0 is housed in a PLQP0176KB-A package: a 176-pin low-profile fine-pitch ball grid array measuring 24 × 24 mm with 0.5-mm pitch. It supports –40°C to +85°C operation (D-version) and provides 127 general-purpose I/O pins with 5-V tolerance on 19 pins, open-drain capability, and programmable pull-up resistors. The R5F571MJCGFP#V0's pinout is fully documented in Renesas' R01DS0249EJ0120 datasheet, pages 42–47.
