Product details
Overview
R5F571MJCDFB#30 from Renesas is a 32-bit RXv2 core microcontroller operating at up to 240 MHz, delivering 480 DMIPS and integrated single-precision IEEE-754 FPU. It integrates 4 MB code flash, 512 KB SRAM (including 32 KB ECC RAM), dual 12-bit ADCs (29 total channels), IEEE 1588-compliant Ethernet MAC, high-speed USB 2.0 with battery charging, and CAN v2.0B - deployed in industrial gateways requiring deterministic real-time control, secure connectivity, and multi-protocol edge processing.
For engineers reviewing the R5F571MJCDFB#30 datasheet, R5F571MJCDFB#30 pinout, R5F571MJCDFB#30 application, or R5F571MJCDFB#30 equivalent, this MCU supports IEC60730 safety compliance via built-in CRC, oscillation-stop detection, self-diagnostic A/D, and register write protection - critical for functional safety certification in motor drives and energy management systems.
Technical Context
The R5F571MJCDFB#30 implements the RXv2 CISC Harvard architecture with 5-stage pipeline, variable-length instructions, and memory protection unit (MPU) for secure embedded execution. Its clock system combines external crystal (8–24 MHz), internal HOCO/LOCO oscillators, and PLL to generate independent clocks: ICLK up to 240 MHz for CPU, PCLKA up to 120 MHz for Ethernet/USB/AES, and PCLKB up to 60 MHz for timers/peripherals.
It features three DMA controllers - DMAC (8 channels), EXDMAC (2 channels), and EDMAC (3 channels for Ethernet) - enabling concurrent high-bandwidth data movement without CPU intervention. The ELC (Event Link Controller) provides hardware-level interconnection of 119 internal event signals, allowing timer-triggered ADC conversions, PWM dead-time compensation, and RTC time-capture on external events - eliminating software latency in time-critical control loops.

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 |
|---|---|---|---|
| R5F571MLDFB#30 | Same RX71M family, identical 176-pin LFBGA package, but with 2.5 MB code flash and 384 KB SRAM - 37.5% less flash and 25% less RAM than R5F571MJCDFB#30. | Suitable for cost-sensitive motor control where full 4 MB flash is unused; not recommended for Ethernet+USB+CAN concurrent firmware images. | Select when BOM cost reduction is prioritized over future firmware scalability and multi-protocol stack headroom. |
