Key Parameters

Substitute Part Grouping Explanation

Substitution of the R5F571MJGDFC#30 is determined by strict equivalence across the following critical parameters:

Processor Architecture & Performance: The substitute must utilize the identical RXv2 core processor at 240MHz to ensure instruction set compatibility and performance parity.

Memory Configuration: Program memory must be 3MB FLASH, EEPROM must be 64K x 8, and RAM must be 512K x 8 to maintain functional equivalence in application code execution and data storage capacity.

Electrical Specifications: Supply voltage range of 2.7V ~ 3.6V and operating temperature range of -40°C ~ 85°C must be maintained for circuit compatibility.

Connectivity & Peripherals: All connectivity interfaces (CANbus, EBI/EMI, Ethernet, I2C, MMC/SD, QSPI, SCI, SPI, SSI, USB OTG) and peripheral functions (DMA, LVD, POR, PWM, WDT) must be present and identical.

Package & Pinout: The 176-LFQFP (24x24) surface mount package with 127 I/O pins must be maintained for PCB layout compatibility.

Compliance & Certifications: RoHS3 compliance, MSL 3 rating, and REACH unaffected status must be preserved.

The R5F571MJCDFC#30 qualifies as a parametric equivalent based on identical specifications across all these criteria, with the only difference being packaging format (Tray versus standard packaging).
