Freescale Semiconductor Inc. has rolled out a single-chip device in its S12 MagniV mixed-signal microcontroller (MCU) family that enables software compatibility and tool reuse across a broad range of applications. The S12VR64 is designed for use in DC motors for automotive window lift and sunroof applications connected to local interconnect network (LIN) automotive body networks.

Based on Freescale's LL18UHV technology, the S12VR64 MCU enables analog integration so developers can connect high-voltage signals and power supplies directly to the MCU in their automotive designs. This helps save board space, increase system quality and reduce complexity. The LL18UHV technology uses Freescale's low-leakage 0.18?m (LL18) fabrication process to integrate 40V analog, non-volatile memory (NVM) and digital logic on a single piece of silicon. The technology also enables the S12VR64 to combine the 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. The fewer components that used ultimately reduce the weight of the automobile.

The S12VR64 is included in Freescale's product longevity program, with assured supply for a minimum of 15 years.

Samples of the S12VR64 MCU are available now. Freescale expects the S12VR64 to achieve automotive AEC-100 qualification by early 2012. Budgetary pricing is $1.65 in 10,000-piece quantities.
