Substitute Part Grouping Explanation

Substitution of R5F3650TDFB#V2 with R5F3650TDFB#10 is based on strict equivalence across all critical electrical and mechanical parameters. Both devices share identical specifications in the following determinative categories:

Core Architecture: Both utilize the M16C/60 processor core with 16-bit architecture and 32MHz operating frequency.

Memory Configuration: Identical program memory (768KB FLASH), EEPROM (8K x 8), and RAM (47K x 8) allocations.

Electrical Characteristics: Matching voltage supply range (2.7V ~ 5.5V), identical I/O count (85 pins), and equivalent data converter specifications (A/D 26x10b; D/A 2x8b).

Connectivity and Peripherals: Identical interface support (EBI/EMI, I2C, SIO, UART/USART) and peripheral set (DMA, LVD, POR, PWM, WDT).

Physical Package: Both devices use 100-LQFP (14x14) surface mount packaging with identical thermal and environmental specifications.

Compliance: Both maintain ROHS3 compliance, identical MSL rating (3), and REACH Unaffected status.

The primary distinction is product status: R5F3650TDFB#V2 is Obsolete, while R5F3650TDFB#10 maintains Active status. The packaging designation differs (V2 indicates standard packaging; #10 indicates Tray packaging), reflecting distribution format rather than functional capability.
