Substitute Part Grouping Explanation

Substitution eligibility for the R7F7010323AFP#KA3 is determined by strict equivalence across the following critical parameters:

• Series and Core Processor: Must be RH850/F1L series with RH850G3K core processor
• Memory Configuration: Program memory must be 768KB FLASH, EEPROM 32K x 8, RAM 96K x 8
• Performance Specifications: Core size (32-Bit Single-Core), speed (80MHz), and I/O count (150) must match exactly
• Connectivity and Peripherals: CANbus, CSI, I2C, LINbus, SPI, UART/USART connectivity and DMA, PWM, WDT peripherals must be present
• Electrical Specifications: Voltage supply range (3V ~ 5.5V), data converter configuration (A/D 28x10b, 32x12b), and operating temperature range (-40°C ~ 105°C) must be identical
• Package and Mounting: 176-LQFP (24x24) surface mount package is mandatory
• Compliance: RoHS3 compliance and MSL 3 rating must be maintained

The R7F7010323AFE#KA4 meets all substitution criteria and qualifies as a direct equivalent part.
