Substitute Part Grouping Explanation

Substitution eligibility for the R7F7010254AFP#AA2 is determined by strict equivalence across the following critical parameters:

Core Architecture & Performance: The substitute part must utilize the identical RH850G3K core processor, maintain 32-bit architecture, and operate at 80MHz to ensure binary compatibility with existing firmware and software stacks.

Memory Configuration: Program memory must be 1MB Flash (1M x 8), RAM must be 128KB (128K x 8), and EEPROM must be 32KB (32K x 8). These specifications are non-negotiable for application compatibility.

Electrical Specifications: Supply voltage range must remain 3V ~ 5.5V to support existing power distribution designs without modification.

Connectivity & Peripherals: All connectivity interfaces (CANbus, CSI, I2C, LINbus, SPI, UART/USART) and peripheral functions (DMA, I2S, LCD, LVD, POR, PWM, WDT) must be present and functionally identical.

Package & Pinout: The 100-LQFP package with 14x14mm dimensions and 81 I/O pins must be maintained to ensure PCB layout compatibility without redesign.

Environmental Specifications: Operating temperature range of -40°C ~ 125°C must be supported.

Substitution is based solely on these provided parameters. No additional technical criteria are applied.

Parameter Comparison

Engineering Selection Recommendations
