Core Functional Parameters:

RL78/G13 series architecture
16-bit core processor
32MHz operating speed
512KB FLASH memory capacity
32KB RAM capacity
8KB EEPROM capacity
64 I/O pins
1.6V ~ 5.5V supply voltage range
A/D 17x8/10b data converter configuration
CSI, I2C, LINbus, UART/USART connectivity

Engineering Selection Recommendations

Direct Substitutes (80-LFQFP 12x12 Package):

R5F100MLAFB#30, R5F100MLAFB#10, R5F100MLDFB#10, and R5F100MLDFB#30 are direct substitutes for the R5F100MLAFB#V0. All maintain identical electrical specifications, memory configurations, and physical footprint. These parts carry Active product status, ensuring long-term availability and supply chain stability. All are ROHS3 compliant and REACH Unaffected.

Parametric Equivalents (80-LQFP 14x14 Package):

R5F100MLAFA#10, R5F100MLAFA#30, R5F100MLDFA#10, and R5F100MLDFA#30 are parametric equivalents with identical functional specifications but different physical package dimensions (14x14 versus 12x12). These parts are suitable only where PCB layout accommodates the larger footprint. All carry Active product status with ROHS3 compliance and REACH Unaffected status.

Availability & Compliance:

All substitute parts are currently in active production with confirmed inventory. All maintain ROHS3 compliance, REACH Unaffected regulatory status, and MSL 3 (168 Hours) moisture sensitivity rating consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can R5F100MLAFB#30 replace R5F100MLAFB#V0 directly?

A: Yes. R5F100MLAFB#30 is a direct substitute with identical electrical specifications, memory configuration, and 80-LFQFP (12x12) package footprint. The primary difference is product status (Active versus Obsolete) and packaging format (Tray).

Q: What is the difference between the 80-LFQFP (12x12) and 80-LQFP (14x14) packages?

A: Both are 80-pin LQFP packages with identical pin counts and electrical specifications. The 14x14 variant has a larger physical footprint. Selection depends on PCB layout constraints. Electrical functionality is identical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH Unaffected status, consistent with the original R5F100MLAFB#V0.

Q: What does the suffix (#V0, #30, #10) indicate?

A: The suffix denotes packaging and tape/reel configuration. #V0 indicates the original variant. #30 and #10 represent different packaging formats (Tray). Electrical specifications remain identical across all suffixes.

Q: Can I use R5F100MLAFA#10 if my PCB is designed for the 12x12 package?

A: No. R5F100MLAFA#10 uses an 80-LQFP (14x14) package with a larger footprint. PCB redesign would be required. Use 80-LFQFP (12x12) variants for direct compatibility.

Q: Why is R5F100MLAFB#V0 marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. Active substitutes with identical specifications are available to ensure design continuity and supply chain support.

Q: Are there any performance differences between the substitute parts?

A: No. All substitute parts maintain identical core processor architecture, clock speed (32MHz), memory capacity (512KB FLASH, 32KB RAM, 8KB EEPROM), I/O count (64), connectivity options, and peripheral configuration.
