The MC9S12ZVL-Family is an automotive 16-bit microcontroller family using the 180nm NVM + UHV technology that offers the capability to integrate 40V analog components. This family reuses many features from the existing S12 portfolio. The particular differentiating features of this family are the enhanced S12Z core and the integration of “high-voltage” analog modules, including the voltage regulator (VREG) and a Local Interconnect Network (LIN) physical layer. The MC9S12ZVL-Family includes error correction code (ECC) on RAM, FLASH and EEPROM for diagnostic or data storage, a fast analog-to-digital converter (ADC) and a frequency modulated phase locked loop (IPLL) that improves the EMC performance. The MC9S12ZVL-Family delivers an optimized solution with the integration of several key system components into a single device, optimizing system architecture and achieving significant space savings. The MC9S12ZVL-Family delivers all the advantages and efficiencies of a 16-bit MCU while retaining the low cost, power consumption, EMC, and code-size efficiency advantages currently enjoyed by users of existing S12 families. The MC9S12ZVL-Family is available in 48-pin, 32-pin LQFP and 32-pin QFN-EP. In addition to the I/O ports available in each module, further I/O ports are available with interrupt capability allowing wake-up from stop or wait modes. The MC9S12ZVL-Family is a general-purpose family of devices suitable for a wide range of applications. The MC9S12ZVL-Family is targeted at generic automotive applications requiring LIN connectivity. Typical examples of these applications include switch panels and body endpoints for sensors.
