Core Processor: RL78
Core Size: 16-Bit
Speed: 32MHz
Program Memory: 64KB FLASH (64K x 8)
EEPROM: 4K x 8
RAM: 4K x 8
Voltage Supply: 2.4V ~ 5.5V
Number of I/O: 48
Data Converters: A/D 12x8/10b

Engineering Selection Recommendations

The R5F100LEGFA#10 and R5F100LEGFA#30 are electrically and functionally equivalent to the R5F100LEGFB#30. All three parts maintain Active product status and ROHS3 compliance. The substitutes are suitable for applications where the 64-LQFP (12x12) package footprint is compatible with the PCB design. Selection between substitute parts should be based on package footprint requirements and availability. All parts share identical electrical specifications, memory configuration, operating temperature range, and peripheral functionality.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between R5F100LEGFB#30 and its substitutes?

A: The primary difference is the package configuration. The R5F100LEGFB#30 uses a 64-LFQFP (10x10) package, while R5F100LEGFA#10 and R5F100LEGFA#30 use a 64-LQFP (12x12) package. All electrical and functional specifications are identical.

Q: Are the substitute parts pin-compatible with the R5F100LEGFB#30?

A: The substitute parts share the same pin count (64 pins) and identical pin functionality. However, the physical package dimensions differ, requiring PCB layout adjustments to accommodate the different package footprint.

Q: Can I use R5F100LEGFA#10 or R5F100LEGFA#30 as direct replacements in existing designs?

A: Direct replacement requires PCB redesign to accommodate the different package footprint. The electrical functionality and performance are equivalent, but the physical layout differs between the 10x10 and 12x12 packages.

Q: Do all three parts have the same memory specifications?

A: Yes. All three parts feature 64KB FLASH program memory, 4KB EEPROM, and 4KB RAM with identical access characteristics and performance.

Q: What is the significance of the suffix numbers (#10 and #30) in the part numbers?

A: The suffix designates the packaging tape configuration and reel specifications for automated assembly processes. This does not affect the electrical or functional characteristics of the microcontroller.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and share identical moisture sensitivity levels (MSL 3, 168 Hours) and operating temperature ranges.
