Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R5F52318BDFM#30 is determined by strict equivalence across the following critical parameters:

• Core processor architecture (RXv2)
• Series designation (RX231)
• Program memory capacity (512KB FLASH)
• RAM capacity (64KB)
• EEPROM capacity (8KB)
• Package type (64-LQFP 10x10)
• Operating voltage range (1.8V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• I/O pin count (43)
• Mounting type (Surface Mount)

The R5F52318ADFM#30 qualifies as a direct substitute based on identical specifications across all critical electrical and mechanical parameters. Connectivity differences (CANbus and SD/SDIO present in the main part but absent in the substitute) do not preclude substitution in applications that do not require these specific interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the R5F52318BDFM#30 and R5F52318ADFM#30 maintain active production status with identical RoHS3 compliance and REACH unaffected certifications. Selection between these parts should be based on application-specific connectivity requirements. The R5F52318BDFM#30 includes CANbus and SD/SDIO interfaces; the R5F52318ADFM#30 does not. For applications requiring these interfaces, the R5F52318BDFM#30 is the appropriate selection. For applications utilizing only I2C, IrDA, SCI, SPI, SSI, and USB OTG connectivity, either part is electrically and mechanically equivalent. Inventory availability and supply lead times may also inform selection between these active alternatives.

Frequently Asked Questions (FAQ)

Q: Can R5F52318ADFM#30 be used as a direct replacement for R5F52318BDFM#30 in all applications?

A: Direct replacement is possible only in applications that do not require CANbus or SD/SDIO interfaces. Both parts are identical in core processor, memory configuration, I/O count, package type, and operating parameters. Verify that your application does not depend on the CANbus or SD/SDIO connectivity present in the R5F52318BDFM#30 before substituting with R5F52318ADFM#30.

Q: Are there any differences in pin configuration between these parts?

A: Both parts use the 64-LQFP (10x10) package with 43 I/O pins. Pin configuration is identical across both devices.

Q: What is the significance of the "#30" suffix in the part number?

A: The "#30" suffix denotes the packaging specification and handling requirements. Both parts carry this identical suffix, confirming equivalent packaging and moisture sensitivity level (MSL 3, 168 Hours).

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, from a physical and electrical standpoint. Both parts are surface-mount devices in the same 64-LQFP package with identical pin assignments. PCB layouts designed for one part will accommodate the other without modification, provided the application does not require the CANbus or SD/SDIO interfaces exclusive to the R5F52318BDFM#30.

Q: What compliance certifications apply to both parts?

A: Both the R5F52318BDFM#30 and R5F52318ADFM#30 are RoHS3 compliant and REACH unaffected. Both carry MSL 3 rating with 168-hour moisture sensitivity limits.
