Engineering Selection Recommendations

All three parts—R5F100FKAFP#30, R5F100FKDFP#30, and R5F140FKAFP#30—are actively produced by Renesas Electronics and carry identical electrical specifications and mechanical packaging. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

R5F100FKAFP#30 and R5F100FKDFP#30 belong to the RL78/G13 series, while R5F140FKAFP#30 belongs to the RL78/G13A series. The series designation change reflects internal Renesas product evolution; however, all functional parameters remain equivalent for design purposes.

All parts comply with ROHS3 regulations and carry MSL 3 moisture sensitivity classification. Selection should prioritize inventory availability and lead time requirements, as electrical and mechanical compatibility is assured across all three options.

Frequently Asked Questions (FAQ)

Q: Can R5F100FKDFP#30 be used as a direct replacement for R5F100FKAFP#30?

A: Yes. Both parts share identical electrical specifications, memory configuration, I/O count, connectivity interfaces, and 44-LQFP package dimensions. The difference in part number suffix reflects internal Renesas product variants with no functional impact on circuit design or firmware compatibility.

Q: Is R5F140FKAFP#30 compatible with designs using R5F100FKAFP#30?

A: Yes. R5F140FKAFP#30 maintains all electrical parameters and package specifications required for direct substitution. The series designation change from RL78/G13 to RL78/G13A indicates a product line update; however, functional equivalence is preserved.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by matching: core processor (RL78), core size (16-Bit), operating speed (32MHz), program memory (384KB FLASH), RAM (24K x 8), EEPROM (8K x 8), supply voltage range (1.6V ~ 5.5V), I/O count (31), connectivity interfaces (CSI, I2C, LINbus, UART/USART), peripheral set (DMA, LVD, POR, PWM, WDT), package type (44-LQFP 10x10), and operating temperature range (-40°C ~ 85°C).

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

A: All three parts are ROHS3 compliant and carry MSL 3 moisture sensitivity classification. No compliance or certification differences exist that would affect design or manufacturing processes.

Q: Can firmware developed for R5F100FKAFP#30 run on R5F140FKAFP#30?

A: Yes. Firmware compatibility is assured due to identical core processor architecture, memory configuration, and peripheral set. No code modifications are required for substitution.

Q: What is the significance of the part number suffix (FP vs. DP)?

A: The suffix indicates internal Renesas product variants. Both FP and DP variants maintain identical electrical and mechanical specifications for the RL78/G13 series, making them functionally interchangeable in circuit design.
