S12VR: S12 MagniV Mixed-Signal MCU for Relay Driven Motor Applications

The S12VR family is based on a process combing NVM, digital logic and high-voltage analog components into a monolithic solution. These analog components include an automotive voltage regulator, LIN physical layer, low-side drivers, high-side drivers and inputs. The new high-voltage devices are capable of withstanding the rigorous requirements of the automotive environment (up to 40V), which can happen during load dump conditions and are integrated with the industry-proven 16-bit S12 CPU and memory subsystem consisting of ECC-protected flash memory and real EEPROM. This S12 CPU is fully compatible with the S12G family of cost-effective, highly-integrated microcontrollers. That compatibility also extends to the digital peripherals included in the S12VR, such as SPI, SCI serial modules, PWM and timer modules.

The S12VR combines all the elements of a system that saves valuable PCB space, simplifies design and increases overall system quality and reduces cost. A smaller PCB means smaller enclosures for automotive applications where every bit of weight removed increases fuel efficiency. The integration of different components on the S12VR reduces time-to-market by requiring less development time to get to a complete solution.
