Integrated S12 Based Relay Driver with LIN

The MM912G634 (48 kB) and MM912H634 (64 kB) are integrated single package solutions that integrates 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.
