Substitute Part Grouping Explanation

Substitute parts for the R5F571MLCDFB#30 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Equivalence Criteria:

• Identical core processor architecture (RXv2)
• Matching processor speed (240MHz)
• Identical program memory capacity (4MB FLASH)
• Identical RAM capacity (512KB)
• Identical EEPROM capacity (64KB)
• Identical supply voltage range (2.7V ~ 3.6V)
• Identical I/O pin count (111)
• Identical data converter specifications (A/D 8x12b, 21x12b; D/A 2x12b)
• Identical peripheral feature set (DMA, LVD, POR, PWM, WDT)
• Identical connectivity interfaces (CANbus, EBI/EMI, Ethernet, I2C, MMC/SD, QSPI, SCI, SPI, SSI, USB OTG)

Mechanical Compatibility Criteria:

• Identical package type (144-LFQFP 20x20)
• Identical pin configuration
• Identical thermal characteristics (-40°C ~ 85°C operating range)

Compliance Criteria:
