Freescale Semiconductor has introduced the first single-chip device, the S12VR64 in its S12 MagniV mixed-signal microcontroller (MCU) family. The device is designed for use in DC motors for automotive window lift and sunroof applications connected to local interconnect network (LIN) automotive body networks. The S12VR64 MCU is based on LL18UHV technology which allows developers to connect high-voltage signals and power supplies directly to the MCU in their automotive designs.
The S12VR64 MCU combines different devices required for relay-driven electric motor control, including the LIN physical layers, voltage regulators and low- and high-side drivers, into one device through LL18UHV technology that allows the integration of high-voltage analog, NVM and digital logic on one piece of silicon. "We are leveraging our automotive semiconductor leadership and proven process technology expertise to create a more efficient solution for networked automotive applications," said Reza Kazerounian, Senior Vice-President & General Manager of Freescale's Microcontroller Solutions Group. "The S12VR64 mixed-signal MCU is the first device based on LL18UHV technology, and we will continue to add products to our S12 MagniV family that offer the right levels of precision and intelligence for a range of motor control and lighting applications in body electronics and other areas of the car."
The next parts planned for the S12 MagniV family are single-chip solutions for applications such as brushless DC motor control, LED lighting, stepper motor control, generic LIN slave nodes or a general-purpose MCU combined with high-voltage I/O.
