Substitute Part Grouping Explanation

Substitute parts for the R5F100FJDFP#X0 are identified based on strict electrical and mechanical parameter equivalence within the RL78/G13 microcontroller series. The substitution criteria are:

Core Substitution Parameters:

• Identical core processor architecture (RL78)
• Matching core size (16-Bit)
• Identical clock speed (32MHz)
• Identical program memory capacity (256KB FLASH)
• Identical RAM configuration (20K x 8)
• Identical EEPROM capacity (8K x 8)
• Matching voltage supply range (1.6V ~ 5.5V)
• Identical I/O count (31 pins)
• Identical connectivity interfaces (CSI, I2C, LINbus, UART/USART)
• Identical peripheral set (DMA, LVD, POR, PWM, WDT)
• Identical package form factor (44-LQFP 10x10)
• Identical operating temperature range (-40°C ~ 85°C)

Substitute parts differ only in product status (active vs. obsolete) and packaging configuration (bulk vs. tape & reel), which do not affect functional or electrical compatibility.
