Substitute Part Grouping Explanation
Substitution of the R7F7010574AFP#KA3 is determined by strict equivalence across the following critical parameters:
- Core Architecture: RH850G3K processor and RH850/F1L series membership
- Memory Configuration: 2MB FLASH, 64K EEPROM, 192K RAM
- Processing Speed: 80MHz operation
- I/O Count: 150 I/O pins
- Connectivity Suite: CANbus, CSI, I2C, LINbus, SPI, UART/USART
- Peripheral Set: DMA, PWM, WDT
- Package Specification: 176-LQFP (24x24) surface mount
- Voltage Range: 3V ~ 5.5V supply compatibility
- Environmental Compliance: ROHS3 compliance and MSL rating
The R7F7010574AFE#KA4 meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: the original part is obsolete, while the substitute is active in production.
