The Qorivva MPC5645S represents a new generation of 32-bit microcontrollers targeting single-chip automotive instrument cluster applications. MPC5645S devices are part of the MPC56xxS family of Power Architecture®-based devices. This family has been designed with an emphasis on providing cost-effective and high quality graphics capabilities in order to satisfy the increasing market demand for color Thin Film Transistor (TFT) displays within the vehicle cockpit. Traditional cluster functions, such as gauge drive, real time counter, and sound generation are also integrated on each device.
