Substitute Part Grouping Explanation

Substitute parts for the R5F3650MCDFB#V0 are qualified based on strict parametric equivalence. All substitute parts maintain identical electrical specifications: 16-bit M16C/60 core processor, 32MHz operating frequency, 512KB FLASH program memory, 31KB RAM, 8KB EEPROM, 2.7V to 5.5V supply voltage range, and 100-LFQFP (14x14) package configuration. Connectivity interfaces (EBI/EMI, I2C, SIO, UART/USART), peripherals (DMA, LVD, POR, PWM, WDT), and data converter specifications (A/D 26x10b, D/A 2x8b) are identical across all qualified substitutes.

Substitution is permitted based on the following key parameters:

Core processor architecture and speed
Memory configuration (FLASH, RAM, EEPROM sizes)
Supply voltage range
Package type and pin count
Operating temperature range
RoHS and MSL compliance

Differences in product status (Obsolete, Active, Not For New Designs) and packaging format (Tube vs. Tray) do not affect electrical or mechanical compatibility.
