Substitute Part Grouping Explanation

Substitution of the R7F7010423AFP#KAT is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Core Architecture & Performance: The RH850G3K processor core, 32-bit architecture, and 96MHz operating frequency are non-negotiable substitution criteria. These parameters define the computational capability and instruction set compatibility.

Memory Configuration: Program memory (768KB FLASH), EEPROM (32KB), and RAM (96KB) must be exactly matched. Variations in memory size result in incompatible firmware deployment and operational constraints.

Peripheral & Interface Compliance: All connectivity interfaces (CANbus, CSI, I2C, LINbus, SPI, UART/USART) and integrated peripherals (DMA, LVD, POR, PWM, WDT) must be present and functionally identical.

Electrical Specifications: Supply voltage range (3V ~ 5.5V), operating temperature range (-40°C ~ 105°C), and data converter specifications (A/D 11x10b, 14x12b) must be maintained.

Package & Pinout: The 80-LFQFP (12x12) surface mount package with 65 I/O pins defines the physical and electrical interface. Package compatibility is mandatory for PCB integration.

Product Status Consideration: While the main part is Obsolete, substitute parts with Active status provide supply chain continuity and ongoing manufacturer support.
