MM912H634DM1AER2

The MM912G634 (48 kB) and MM912H634 (64 kB) are integrated single package solutions that integrate an HCS12 MCU 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. Your customer benefits include: Integrated MCU and analog features in the same package solution A full LIN solution Easy control of high-current motors using relays and current sense features Reduced space, resulting in enhanced reliability Full protection for output stages Economical multifunction solution with few components Low-power mode flexibility Reverse-battery-protected voltage sense
