S912ZVML12F3WKH                   Description

The MC9S12ZVM-Family is an automotive 16-bit microcontroller family using the NVM + UHV

technology that offers the capability to integrate 40 V analog components. This family reuses many features from the existing S12/S12X portfolio. The particular differentiating features of this family are the enhanced S12Z core, the combination of dual-ADC synchronized with PWM generation and the integration of “high-voltage” analog modules, including the voltage regulator (VREG), Gate Drive Unit (GDU) and a Local Interconnect Network (LIN) physical layer. These features enable a fully integrated single chip solution to drive up to 6 external power MOSFETs for BLDC or PMSM motor drive applications.
