Product details
Overview
R5F571MGDDFB#30 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 - deployed in industrial gateway controllers requiring real-time protocol handling, secure firmware updates, and deterministic network timing.
For engineers reviewing the R5F571MGDDFB#30 datasheet, R5F571MGDDFB#30 pinout, R5F571MGDDFB#30 application, or R5F571MGDDFB#30 equivalent, this page delivers verified package mapping (176-pin LFBGA, PLQP0176KB-A), confirmed peripheral channel counts (2× ETHERC, 3× CAN, 9× SCI), clock domain assignments (ICLK ≤ 240 MHz, PCLKA ≤ 120 MHz), and functional boundaries for IEEE 1588 PTP, USBAa, and S12ADC unit 1 (21-channel).
Technical Context
The R5F571MGDDFB#30 implements the RXv2 CPU core with Harvard architecture, 5-stage pipeline, and IEEE-754 single-precision FPU - enabling deterministic floating-point execution in motor control and digital power algorithms. Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash (100k write cycles), and 512 KB SRAM split across wait-state domains (0–256 KB: no-wait at 240 MHz; 256–512 KB: one wait above 120 MHz).
Peripheral integration follows strict clock-domain partitioning: ICLK drives CPU and bus masters (≤240 MHz); PCLKA clocks ETHERC, USBAa, and AES (≤120 MHz); PCLKB governs TMR, CMT, and RIIC (≤60 MHz); PCLKC/D drive S12ADC units 0/1 (≤60 MHz). The ELC enables hardware-triggered timer-to-A/D or GPIO-to-PWM chaining without CPU intervention.

FAQ
What is the maximum operating frequency and DMIPS rating of the R5F571MGDDFB#30?
The R5F571MGDDFB#30 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-bit multiply, and IEEE-754 compliant FPU - enabling real-time control algorithms in motor drives and power converters where deterministic execution is critical. The R5F571MGDDFB#30 sustains this performance across its full voltage range (2.7–3.6 V) and industrial temperature grade (–40°C to +85°C).
Does the R5F571MGDDFB#30 support IEEE 1588 Precision Time Protocol, and how is it implemented?
Yes, the R5F571MGDDFB#30 integrates a dedicated IEEE 1588-compliant PTP controller (EPTPCa) tightly coupled to its dual Ethernet MAC (ETHERC). Hardware timestamping occurs at the MAC layer with sub-100 ns resolution, and the EPTPC block handles synchronization message processing, delay measurement, and clock correction - all without CPU intervention. This implementation meets Class C timing requirements for industrial automation and substation automation per IEC 61850-9-3. The R5F571MGDDFB#30 requires an external 25 MHz crystal for optimal PTP accuracy.
What are the memory resources available on the R5F571MGDDFB#30?
The R5F571MGDDFB#30 includes 4 MB of on-chip code flash memory with background programming/erasing (BGO), 64 KB of reprogrammable data flash (rated for 100,000 write cycles), 512 KB of general-purpose SRAM (with 256 KB accessible at zero wait states even at 240 MHz), 32 KB of ECC-protected RAM (SEC-DED), and 8 KB of battery-backed standby RAM. These resources enable robust firmware partitioning, secure key storage, real-time data buffering, and RTC persistence - all verified in the R01DS0249EJ0120 datasheet for the R5F571MGDDFB#30.
Which communication interfaces are supported by the R5F571MGDDFB#30 for industrial connectivity?
The R5F571MGDDFB#30 supports dual IEEE 802.3 Ethernet MACs (10/100 Mbps), three ISO 11898-1 CAN channels (32 mailboxes each), nine serial communication interfaces (SCIg/h) with UART/I²C/SPI emulation, four FIFO-equipped SCIFA ports, two I²C buses (up to 1 Mbps), two RSPI interfaces, one quad-SPI, one SD host interface (SDHI), one MMC interface (MMCIF), and high-speed USB 2.0 with battery charging (USBAa). All are confirmed in the R5F571MGDDFB#30's package-specific feature table and operate within defined clock domains (PCLKA/PCLKB) per the official Renesas documentation.
What is the package type and pin count of the R5F571MGDDFB#30?
The R5F571MGDDFB#30 uses the PLQP0176KB-A package: a 176-pin Low-Profile Fine-Pitch Ball Grid Array with 24 mm × 24 mm body size and 0.5 mm ball pitch. This matches the 176-pin LFBGA footprint defined in Renesas' RX71M Group documentation and supports all peripheral functions listed for 176/177-pin variants - including dual Ethernet, high-speed USB, and 127 GPIOs. The R5F571MGDDFB#30's pinout is fully documented in Section 5 (Pin Functions) of the R01DS0249EJ0120 datasheet.
