Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the R5F104FGAFP#10 are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Core Processor Architecture: Both the main part and substitute must utilize the RL78 core processor operating at 16-bit architecture with 32MHz clock speed.

Memory Configuration: Identical program memory capacity (128KB FLASH), EEPROM size (8K x 8), and RAM allocation (16K x 8) are required to ensure software compatibility and functional equivalence.

Package Geometry: The 44-LQFP (10x10) surface mount package specification must be maintained to ensure PCB layout compatibility and mechanical fit.

Electrical Specifications: Voltage supply range (1.6V ~ 5.5V), I/O count (31 pins), and peripheral feature set (CSI, I2C, LINbus, UART/USART, DMA, LVD, POR, PWM, WDT) must remain constant.

Compliance & Certification: RoHS3 compliance, REACH unaffected status, and MSL rating (3) must be preserved.

The R5F104FGAFP#10 and R5F104FGAFP#30 share identical parametric specifications across all these criteria, establishing them as direct parametric equivalents within the RL78/G14 microcontroller family.

Parameter Comparison
