Freescale TRK-S12VR-WLFT Window Lift and Relay-Based DC Motor Control Hardware Reference Design

About this manual

The document describes a reference hardware platform for automotive window lift, sun‑roof and zone systems, using a Freescale S12VR 16‑bit MCU. It includes a relay driver, LIN interface, Hall sensor inputs, temperature and battery voltage monitoring, and supports operation from 8‑18 V.

The kit provides a DVD with CodeWarrior, anti‑pinch software, a design reference manual and a quick‑start guide. Relay status and diagnostics can be accessed via LIN and the HVIX wake‑up pin, and the board is sold as a StarterTRAK development platform. This manual is written in Chinese.
