Engineering Selection Recommendations
All substitute parts listed maintain active product status with Renesas Electronics Corporation and carry identical RoHS3 compliance and REACH unaffected certifications. Selection between R5F100LDGFB#10 and its substitutes is determined by printed circuit board layout requirements and packaging constraints.
R5F100LDGFB#10 and R5F100LDGFB#30 are functionally equivalent, both utilizing the 64-LFQFP (10x10) package format. The primary distinction is the tape reel configuration (#10 versus #30), which affects supply chain and procurement parameters but not electrical performance.
R5F100LDGFA#10 and R5F100LDGFA#30 employ the 64-LQFP (12x12) package format, which differs in physical dimensions from the LFQFP variant. PCB footprint design and component placement must accommodate the larger package dimensions. Both LQFP variants maintain identical electrical specifications and functional capabilities.
Selection of LFQFP (10x10) or LQFP (12x12) packaging is determined by available board space and design constraints. No electrical or functional differences exist between these package variants for this microcontroller series.
Frequently Asked Questions (FAQ)
Q: Are R5F100LDGFB#10 and R5F100LDGFA#10 electrically interchangeable?
A: Yes. Both parts share identical electrical specifications, memory configurations, operating frequency, supply voltage range, and peripheral sets. The primary difference is the package format: R5F100LDGFB#10 uses 64-LFQFP (10x10) while R5F100LDGFA#10 uses 64-LQFP (12x12). PCB footprint design must accommodate the selected package variant.
Q: What is the difference between #10 and #30 designations?
A: The #10 and #30 suffixes indicate different tape reel configurations for surface mount component packaging. These designations affect supply chain logistics and component handling but do not alter electrical performance or functional characteristics.
Q: Can I substitute R5F100LDGFB#10 with R5F100LDGFA#30?
A: Electrical substitution is valid. However, the 64-LQFP (12x12) package used in R5F100LDGFA#30 has different physical dimensions than the 64-LFQFP (10x10) package of R5F100LDGFB#10. PCB layout and footprint design must be modified to accommodate the larger package size.
Q: Do all substitute parts maintain the same compliance certifications?
A: Yes. All parts listed carry RoHS3 compliance and REACH unaffected status. Moisture sensitivity level is identical across all variants at MSL 3 (168 Hours).
Q: Are there memory differences between the main part and substitutes?
A: No. All parts feature identical memory configurations: 48KB FLASH program memory, 4KB EEPROM, and 3KB RAM.
Q: What connectivity interfaces are available on all substitute parts?
A: All substitute parts include CSI, I2C, LINbus, and UART/USART connectivity interfaces with identical peripheral support including DMA, LVD, POR, PWM, and WDT.
Q: Is the operating temperature range the same for all variants?
