Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R7F7015834AFP-C#BA3 is determined by strict equivalence across the following critical parameters:

Core Processor Architecture: Both the main part and substitute must utilize the RH850G3KH core to ensure instruction set compatibility and firmware portability.

Memory Configuration: Program memory (2MB FLASH), EEPROM (64K x 8), and RAM (192K x 8) must be identical to maintain software compatibility and system functionality.

Operating Frequency: 120MHz operation is mandatory for timing-critical applications and peripheral clock generation.

Electrical Specifications: Supply voltage range (3V to 5.5V), I/O count (120 pins), and data converter specifications (A/D 24x10b, 24x12b) must match exactly.

Package and Mechanical: 144-LQFP (20x20mm) package format ensures PCB layout compatibility and assembly process alignment.

Connectivity and Peripherals: CANbus, CSI, I2C, LINbus, SPI, UART/USART interfaces, plus DMA, PWM, and WDT peripherals must be present and functionally equivalent.

Environmental and Compliance: Operating temperature range (-40°C to +125°C), RoHS3 compliance, and MSL 3 rating must be maintained.

The identified substitute R7F7015834AFP-C#AA3 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The R7F7015834AFP-C#BA3 and R7F7015834AFP-C#AA3 are parametric equivalents with identical electrical, mechanical, and functional specifications. Both parts are manufactured by Renesas Electronics Corporation and maintain Active product status, ensuring long-term supply chain viability.

Compliance and Certification:

Both parts comply with ROHS3 environmental standards and carry MSL 3 moisture sensitivity ratings with 168-hour floor life specifications. These certifications are maintained across both part numbers, supporting deployment in regulated automotive and industrial applications.

Inventory Considerations:

The substitute part R7F7015834AFP-C#AA3 currently maintains higher inventory availability (1061 units) compared to the main part number (777 units). This inventory differential may influence procurement decisions when lead time or bulk order requirements are factors.

Design Integration:

No design modifications, firmware changes, or PCB layout adjustments are required when substituting between these part numbers. Pin configuration, package footprint, and electrical characteristics are fully compatible.

Supply Chain Flexibility:

Both part numbers represent the same functional device with identical performance characteristics. Selection between them should be based on availability, delivery timeline, and supplier preference rather than technical differentiation.

Frequently Asked Questions (FAQ)

Q: Are R7F7015834AFP-C#BA3 and R7F7015834AFP-C#AA3 pin-for-pin compatible?

A: Yes. Both parts use the 144-LQFP (20x20mm) package with 120 I/O pins in identical pin configurations. PCB layouts designed for one part number are directly compatible with the other without modification.

Q: Can firmware developed for R7F7015834AFP-C#BA3 run on R7F7015834AFP-C#AA3 without recompilation?

A: Yes. Both parts utilize the identical RH850G3KH core processor running at 120MHz with identical memory configurations (2MB FLASH, 192K RAM, 64K EEPROM). Compiled firmware is directly portable between the two part numbers.

Q: What is the difference between the two part numbers?

A: The part numbers differ only in their suffix designations (BA3 versus AA3). All electrical specifications, memory configurations, peripheral sets, and performance characteristics are identical. The suffix variation reflects internal Renesas manufacturing or distribution tracking but does not indicate functional differences.

Q: Are both parts suitable for automotive applications?

A: Yes. Both R7F7015834AFP-C#BA3 and R7F7015834AFP-C#AA3 support automotive connectivity standards including CANbus and LINbus, operate across the automotive temperature range (-40°C to +125°C), and comply with ROHS3 environmental standards required for automotive deployment.

Q: What is the moisture sensitivity level, and how does it affect handling?

A: Both parts carry MSL 3 rating with 168-hour floor life. This means the components can be exposed to ambient conditions (typically 23°C ± 2°C, 45% to 75% relative humidity) for up to 168 hours after moisture barrier bag opening before requiring baking. Proper moisture control during storage and assembly is required to prevent solder joint defects.

Q: Can these parts be used interchangeably in existing production?

A: Yes. No design changes, firmware updates, or assembly process modifications are required. Both parts are direct substitutes from an engineering perspective and can be used interchangeably in production environments.

Q: What supply voltage range do these microcontrollers support?

A: Both parts operate across a 3V to 5.5V supply voltage range, supporting both 3.3V and 5V logic systems commonly used in industrial and automotive applications.

Q: How many I/O pins are available for application-specific functions?

A: Both parts provide 120 I/O pins in the 144-LQFP package. Pin allocation includes dedicated pins for power, ground, and oscillator functions, with the remaining pins available for application-specific connectivity including CANbus, SPI, I2C, UART/USART, and general-purpose digital I/O.
