Substitute Part Grouping Explanation

Substitution of the R7F7010293AFP#AA4 with R7F7010293AFP-C#AA4 is based on strict equivalence of the following critical parameters:

Core Functional Parameters:

• Identical core processor (RH850G3K) and architecture (32-bit single-core)
• Matching clock speed (80MHz)
• Identical memory configuration: 1MB FLASH, 128KB RAM, 32KB EEPROM
• Identical I/O count (120 pins)
• Matching voltage supply range (3V ~ 5.5V)
• Identical operating temperature range (-40°C ~ 105°C)

Connectivity & Peripherals:

• Both support CANbus, CSI, I2C, LINbus, SPI, and UART/USART
• Both include DMA, PWM, and WDT peripherals
• Matching A/D converter configuration (24x10b, 24x12b)

Compliance & Packaging:

• Both are automotive-grade with AEC-Q100 qualification
• Both are ROHS3 compliant and REACH unaffected
• Both use 144-LQFP surface mount packaging
• Identical MSL rating (3, 168 Hours)

The primary distinction is product status: the original part is obsolete, while the substitute is active, with enhanced peripheral support (I2S, LCD, LVD, POR added in substitute).
