Substitute Part Grouping Explanation

Substitution of the S9S12VR48F2CLC is determined by strict equivalence across the following critical parameters:

Processor Core & Architecture: 12V1 core, 16-bit S12 MagniV series
Memory Configuration: 48KB FLASH, 512 bytes EEPROM, 2KB RAM
Operating Frequency: 25MHz
Supply Voltage Range: 3.13V ~ 5.5V
Peripheral Set: IrDA, LINbus, SCI, SPI connectivity; LVD, POR, PWM, WDT functions
I/O Count: 16 I/O pins
Package Specification: 32-LQFP (7x7) surface mount
