Substitute Part Grouping Explanation

Substitution of the R5F564MLDDFB#31 is determined by strict equivalence across the following critical parameters:

Processor Architecture: RXv2 core with identical instruction set
Memory Configuration: 4MB FLASH, 552KB RAM, 64KB EEPROM
Clock Speed: 120MHz operation
Package Type: 144-LQFP (20x20) form factor
Electrical Specifications: 2.7V to 3.6V supply voltage range
Peripheral Set: Identical connectivity (CANbus, Ethernet, USB, SCI, SPI, I2C, LINbus, MMC/SD, SSI, EBI/EMI) and integrated functions (DMA, LVD, POR, PWM, WDT)
Data Converters: 29x12-bit A/D and 2x12-bit D/A
Compliance: ROHS3 and REACH compliance maintained

The identified substitutes R5F564MLCDFB#31 and R5F564MLHDFB#31 meet all these criteria and are functionally interchangeable at the system level.

Engineering Selection Recommendations

Both R5F564MLCDFB#31 and R5F564MLHDFB#31 are direct functional equivalents of the R5F564MLDDFB#31. The primary distinction is product status: the original part is discontinued, while both substitutes maintain active status with Renesas Electronics Corporation.

Selection between the two substitute parts should be based on:

Availability: R5F564MLCDFB#31 (861 units in stock) and R5F564MLHDFB#31 (840 units in stock) are both available
Packaging: Both substitutes are supplied in Tray packaging, which may differ from the original part's packaging specification
Compliance: Both substitutes maintain ROHS3 and REACH compliance identical to the original part

No technical differentiation exists between the substitute parts based on provided specifications. Selection may be determined by procurement lead times and packaging requirements.

Frequently Asked Questions (FAQ)

Q: Are R5F564MLCDFB#31 and R5F564MLHDFB#31 pin-compatible with R5F564MLDDFB#31?
