For engineers reviewing the R5F571MLHDFC#30 datasheet, R5F571MLHDFC#30 pinout, R5F571MLHDFC#30 application, or R5F571MLHDFC#30 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LFBGA, 24 × 24 mm, 0.5-mm pitch), functional pin roles, real-world use cases, and two validated alternative MCUs - all grounded in Renesas R01DS0249EJ0120 Rev.1.20 documentation.
Technical Context
The R5F571MLHDFC#30 implements the RXv2 CPU core with CISC Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code. It integrates dual Ethernet controllers with IEEE 1588 PTP hardware timestamping, supported by dedicated EDMAC (3-channel) and EPTPC modules for sub-microsecond time synchronization in industrial automation networks.
Its memory subsystem includes 4 MB code flash with background programming, 64 KB data flash rated for 100,000 erase/write cycles, and segmented SRAM: 256 KB zero-wait at 240 MHz (0000_0000h–0003_FFFFh), plus 32 KB ECC RAM for safety-critical firmware execution. Clocking supports external crystal (8–24 MHz) + PLL, HOCO (16/18/20 MHz), and LOCO (240 kHz), with independent PCLKA (≤120 MHz), PCLKB (≤60 MHz), and ADCLK domains.

All memory blocks are accessible via the 32-bit linear address space.
Which USB capabilities does the R5F571MLHDFC#30 provide?
The R5F571MLHDFC#30 features two USB modules: a high-speed USB 2.0 host/function module (USBAa) supporting 480 Mbps with battery charging detection, and a full-speed USB 2.0 host/function module (USBb) supporting 12 Mbps. Both include integrated transceivers and on-chip RAM buffers (8.5 KB for USBAa, 2 KB for USBb), eliminating external PHY requirements.
Is the R5F571MLHDFC#30 pin-compatible with other RX71M group members?
The R5F571MLHDFC#30 uses the PLQP0176KB-A 176-pin LFBGA package and shares pinout compatibility with other 176- and 177-pin RX71M variants (e.g., R5F571MLHDFP#30, R5F572MLHDFC#30). However, peripheral enablement (e.g., SDHI, second Ethernet channel) varies by part number - always verify signal mapping and register configuration against the specific device's datasheet section "Comparison of Functions for Different Packages".
