A Comprehensive Guide To SM912F634DV2AER2 Microcontroller IC 16-Bit 20MHz 32KB (32K x 8) FLASH 48-HLQFP (7x7)

S12 S/MM9 Microcontroller IC 16-Bit 20MHz 32KB (32K x 8) FLASH 48-HLQFP (7x7)

Integrated S12 Based Relay Driver with LIN

The S/MM912F634 is an integrated single package solution integrating

an HCS12 microcontroller with a SMARTMOS analog control IC. The

Die to Die Interface (D2D) controlled analog die combines system base

chip and application specific functions, including a LIN transceiver.
