Substitute Part Grouping Explanation

Substitute parts for the R5F571MFHDFP#10 are identified based on strict parametric equivalence within the RX71M microcontroller family. The substitution logic is based on the following critical parameters that must remain identical:

• Processor Architecture: RXv2 core
• Series Classification: RX71M
• Clock Speed: 240MHz
• Memory Configuration: 2MB FLASH, 512KB RAM, 64KB EEPROM
• Package Format: 100-LFQFP (14x14)
• I/O Count: 78 pins
• Voltage Specification: 2.7V ~ 3.6V supply range
• Connectivity Interfaces: CANbus, EBI/EMI, Ethernet, I2C, MMC/SD, QSPI, SCI, SPI, SSI, USB OTG
• Peripheral Set: DMA, LVD, POR, PWM, WDT
• Data Converters: A/D 22x12b, D/A 1x12b
• Compliance Standards: ROHS3, REACH unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Variations in internal die revision, manufacturing date code, or packaging tray configuration do not affect functional or electrical equivalence.

Parameter Comparison
