For engineers reviewing the R5F571MJCDFP#30 datasheet, R5F571MJCDFP#30 pinout, R5F571MJCDFP#30 application, or R5F571MJCDFP#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), validated pin functions, and two confirmed alternative MCUs - all extracted from Renesas R01DS0249EJ0120 Rev.1.20 and official product documentation.

Technical Context

The R5F571MJCDFP#30 implements the RXv2 CPU core with single-precision IEEE-754 FPU, dual multiply-accumulate units, and memory protection unit (MPU) for functional safety compliance (IEC60730). Its clock system supports external crystal (8–24 MHz) or internal PLL, with independent domain clocks: ICLK up to 240 MHz, 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 via EPTPCa, three CAN modules (32 mailboxes each), and a full-featured SD host interface (SDHI) supporting 15 MB/s high-speed mode. The device includes 127 GPIOs (19 with 5-V tolerance), four low-power modes, and battery-backed RTC with time-capture capability.

FAQ

What is the maximum operating frequency and DMIPS rating of the R5F571MJCDFP#30?

The R5F571MJCDFP#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 multiplier, and dual MAC units. The R5F571MJCDFP#30 maintains zero wait states for code execution up to 120 MHz, ensuring deterministic real-time response in time-critical industrial applications.

Does the R5F571MJCDFP#30 support IEEE 1588 Precision Time Protocol?

Yes, the R5F571MJCDFP#30 includes dedicated hardware for IEEE 1588 compliance via the EPTPCa (PTP Controller for Ethernet) module, which connects directly to both Ethernet MACs. It supports hardware timestamping of ingress/egress frames with sub-microsecond accuracy, enabling precise time synchronization in industrial Ethernet networks without CPU intervention or software jitter.

What package type and pin count does the R5F571MJCDFP#30 use?

The R5F571MJCDFP#30 uses the PLQP0176KB-A package: a 176-pin Low-profile Quad Flat Package measuring 24 mm × 24 mm with 0.5 mm pitch. This RoHS-compliant LQFP includes an exposed thermal pad and supports industrial temperature range (–40°C to +105°C). Pin compatibility is maintained across RX71M 176-pin variants, including R5F571MLDFP#30 and R5F571MJDFP#30.

How many Ethernet MACs and CAN interfaces does the R5F571MJCDFP#30 integrate?

The R5F571MJCDFP#30 integrates two IEEE 802.3-compliant Ethernet MACs with MII/RMII support and three independent CAN modules (ISO 11898-1 compliant), each with 32 configurable mailboxes. Both Ethernet MACs support IEEE 1588 timestamping and cut-through forwarding, while the CAN modules support standard and extended frames - enabling robust multi-protocol industrial networking in a single chip.

Is the R5F571MJCDFP#30 suitable for IEC60730 Class B safety certification?

Yes, the R5F571MJCDFP#30 includes multiple hardware features required for IEC60730 Class B compliance, including oscillation-stop detection, CRC calculation unit, independent watchdog timer (IWDTa) with window function, self-diagnostic A/D converter test, and register write protection. These capabilities are documented in Renesas Application Note R01AN3819JJ0100 and supported by the built-in MPU and ECC RAM.
