Engineering Selection Recommendations

The R7F100GLG2DFA#HA0 is a direct parametric equivalent to the R7F100GLG2DFB#HA0. Both devices are manufactured by Renesas Electronics Corporation, maintain active product status, and comply with ROHS3 environmental standards. The sole distinction between these parts is the physical package dimension: the main part features a 10x10mm footprint while the substitute features a 12x12mm footprint, both within the 64-LQFP package family.

Selection between these two parts should be based on PCB layout constraints and available board space. The 10x10mm variant (R7F100GLG2DFB#HA0) is suitable for space-constrained applications, while the 12x12mm variant (R7F100GLG2DFA#HA0) may offer improved thermal characteristics and easier PCB routing due to increased pad spacing. Both parts carry identical electrical specifications, memory configurations, peripheral sets, and compliance certifications, ensuring functional interchangeability within the design.

Frequently Asked Questions (FAQ)

Q: Are R7F100GLG2DFB#HA0 and R7F100GLG2DFA#HA0 functionally identical?

A: Yes. Both devices are functionally identical with respect to all electrical parameters, memory configuration, peripheral functionality, and operating characteristics. They differ only in physical package dimensions.

Q: What is the difference between the 10x10mm and 12x12mm package variants?

A: The 10x10mm package (R7F100GLG2DFB#HA0) provides a smaller footprint suitable for space-constrained designs. The 12x12mm package (R7F100GLG2DFA#HA0) offers increased pad spacing, which may facilitate PCB routing and potentially improve thermal dissipation. Both are 64-LQFP packages with identical pin counts and electrical characteristics.

Q: Can I substitute R7F100GLG2DFA#HA0 for R7F100GLG2DFB#HA0 on an existing PCB?

A: Direct PCB substitution is not possible without layout modification due to the different package dimensions. The 12x12mm footprint requires a larger PCB area than the 10x10mm footprint. PCB redesign is necessary to accommodate the larger package.

Q: Are both parts RoHS compliant?

A: Yes. Both R7F100GLG2DFB#HA0 and R7F100GLG2DFA#HA0 are ROHS3 compliant and carry identical MSL ratings of 3 (168 Hours).

Q: What is the supply voltage range for both parts?

A: Both parts operate with a supply voltage range of 1.6V to 5.5V, providing flexibility for various power supply configurations.

Q: Do both parts support the same connectivity interfaces?

A: Yes. Both devices support identical connectivity: CSI, I2C, LINbus, SPI, and UART/USART interfaces.

Q: Are there any differences in memory configuration between these parts?

A: No. Both parts feature identical memory: 128KB FLASH program memory, 16KB RAM, and 8KB EEPROM.

Q: What is the operating temperature range for both devices?

A: Both parts operate across the temperature range of -40°C to 85°C (TA).
