Frequently Asked Questions (FAQ)

Q: What is the difference between R5F140GKAFB#30 and R5F100GKAFB#30?

A: The primary difference is the series designation: R5F140 represents the RL78/G13A series, while R5F100 represents the RL78/G13 series. All electrical specifications, memory sizes, peripheral functions, and package dimensions are identical. The suffix #30 indicates the same packaging code for both parts.

Q: Can R5F100GKAFB#10 be used as a direct replacement for R5F140GKAFB#30?

A: Yes. R5F100GKAFB#10 is a parametric equivalent with identical core processor, memory configuration, I/O count, connectivity options, and operating specifications. The #10 packaging code represents a different tape and reel configuration but does not affect functional compatibility.

Q: What do the packaging codes #10 and #30 represent?

A: The packaging codes #10 and #30 indicate different tape and reel configurations or manufacturing date code batches. These codes do not affect the electrical performance or physical package dimensions of the microcontroller.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the R5F140GKAFB#30.

Q: What is the moisture sensitivity level for these microcontrollers?

A: All parts maintain MSL 3 (168 Hours), indicating that the devices must be stored in controlled humidity conditions and used within 168 hours of exposure to ambient conditions above 30°C and 85% relative humidity.

Q: Can I mix different packaging codes (#10 and #30) in the same production run?

A: Yes. Since packaging codes represent only tape and reel configuration differences and do not affect electrical or mechanical specifications, parts with different packaging codes can be used interchangeably in the same design.

Q: What is the operating temperature range for all these microcontrollers?

A: All parts operate across the temperature range of -40°C to 85°C (TA), suitable for industrial and automotive embedded applications.

Q: Are there any differences in the A/D converter specifications between the main part and substitutes?

A: No. All parts feature identical A/D converter specifications: 10 channels, 8-bit or 10-bit resolution.
