Automotive window lift reference design features analogue-integrated Freescale MCU

Freescale and Tongji University (Shanghai, China) have jointly developed a reference design for automotive window lift systems. The reference design, based on Freescale’s S12 MagniV S12VR64 mixed-signal microcontroller, provides a ready-to-use, rugged anti-pinch window lift control system.

The single-chip S12VR64 is built on Freescale’s LL18UHV technology, which enables extensive analogue integration on the MCU so developers can connect high-voltage signals and power supplies directly to the MCU in their automotive designs. Freescale says this “direct-connect” capability helps save board space, increase system quality and reduce complexity and cost.

Traditionally, automotive electronic designs have required multiple devices, including some created with a high-voltage process to connect to the battery and power actuator outputs, as well as MCUs created with a low-voltage digital logic process. This poses a challenge when the end application has space limitations.

The window lift reference design is available now on a limited basis from Freescale.
