Parameter Comparison

Engineering Selection Recommendations

All three microcontroller variants—R7F100GPL3CFB#BA0, R7F100GPL3CFA#AA0, and R7F100GPL3CFA#BA0—are manufactured by Renesas Electronics Corporation and maintain Active product status. Each device is ROHS3 compliant and carries identical MSL ratings of 3 (168 Hours), ensuring equivalent environmental and regulatory compliance for industrial and commercial applications.

The electrical and functional specifications are identical across all three parts. Selection between these variants is determined solely by physical package dimensions. The main part R7F100GPL3CFB#BA0 utilizes a 14x14mm footprint, while the substitute parts R7F100GPL3CFA#AA0 and R7F100GPL3CFA#BA0 utilize a 14x20mm footprint. PCB layout and available board space dictate which package variant is appropriate for a given application.

All three parts are suitable for applications requiring 16-bit microcontroller functionality with integrated analog and digital signal processing, communication interfaces, and embedded control capabilities within the specified voltage and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between R7F100GPL3CFB#BA0 and its substitute parts?

A: The primary difference is the physical package dimension. R7F100GPL3CFB#BA0 is housed in a 100-LQFP package measuring 14x14mm, while R7F100GPL3CFA#AA0 and R7F100GPL3CFA#BA0 are housed in 100-LQFP packages measuring 14x20mm. All electrical specifications and functional capabilities are identical.

Q: Are these parts electrically interchangeable?

A: Yes. R7F100GPL3CFA#AA0 and R7F100GPL3CFA#BA0 are electrically and functionally equivalent to R7F100GPL3CFB#BA0. They share identical core processor architecture, memory configuration, operating voltage, speed, connectivity interfaces, and peripheral functions.

Q: What determines whether I can use a substitute part?

A: Substitution is determined by PCB layout constraints and available board space. If your design accommodates the 14x20mm package footprint, either R7F100GPL3CFA#AA0 or R7F100GPL3CFA#BA0 can be used. If your design requires the 14x14mm footprint, R7F100GPL3CFB#BA0 is the appropriate selection.

Q: Do all three parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, carry MSL rating 3 (168 Hours), and maintain Active product status from Renesas Electronics Corporation.

Q: Can I use these parts interchangeably in firmware development?

A: Yes. Since all electrical specifications, memory sizes, clock speeds, connectivity interfaces, and peripheral functions are identical, firmware developed for one variant operates identically on all three variants.

Q: What is the difference between the suffix codes (#AA0 and #BA0)?

A: The suffix codes indicate different manufacturing batches or date codes. Both variants maintain identical electrical and functional specifications. The suffix does not affect technical compatibility or performance.

Q: Are there any thermal or power consumption differences between these parts?

A: No. All three parts operate within the same voltage range (1.8V ~ 5.5V) and temperature range (-40°C ~ 105°C). Thermal and power characteristics are identical.

Q: Which part should I select for a new design?

A: Selection depends on your PCB layout requirements. If space permits, either substitute part is acceptable. If your design has strict space constraints requiring the smaller 14x14mm footprint, use R7F100GPL3CFB#BA0. For designs with more flexible layout requirements, R7F100GPL3CFA#AA0 or R7F100GPL3CFA#BA0 are suitable alternatives.
