Engineering Selection Recommendations

R5F564MFDDFB#31 is the primary substitute for the discontinued R5F564MFCDFB#31. This part maintains complete parametric equivalence and carries Active product status, ensuring long-term availability and supply chain stability. The packaging format difference (Tray) does not affect electrical or mechanical compatibility. ROHS3 compliance and REACH unaffected status are maintained.

R5F564MFHDFB#V1 is a secondary alternative with identical electrical specifications. However, this part carries Obsolete product status, indicating limited future availability. Selection of this part should be limited to applications requiring immediate component sourcing from existing inventory only.

For new designs or production runs requiring sustained component availability, R5F564MFDDFB#31 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Are these parts pin-compatible? A: Yes. All three parts use the 144-LQFP (20x20mm) package with identical pin assignments, I/O configuration (111 pins), and electrical characteristics.

Q: What is the difference between the packaging formats? A: The main part uses standard packaging, while R5F564MFDDFB#31 and R5F564MFHDFB#V1 use Tray packaging. This affects only the physical delivery format and does not impact component functionality or PCB integration.

Q: Can I use R5F564MFHDFB#V1 in production? A: R5F564MFHDFB#V1 carries Obsolete status. While electrically equivalent, this part should only be used when immediate availability is critical and long-term supply cannot be guaranteed. For sustained production, R5F564MFDDFB#31 is recommended.

Q: Are all three parts ROHS3 compliant? A: Yes. All parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements.

Q: What memory configurations are available across these parts? A: All three parts feature identical memory: 2MB FLASH, 64K EEPROM, and 552K RAM. No memory variants exist among these substitutes.

Q: Do these parts support the same connectivity interfaces? A: Yes. All parts support CANbus, EBI/EMI, Ethernet, I2C, LINbus, MMC/SD, SCI, SPI, SSI, UART/USART, and USB interfaces identically.

Q: What is the operating temperature range? A: All three parts operate across -40°C to 85°C (TA), maintaining identical thermal specifications.
