The Qorivva MPC560xP family of 32-bit microcontrollers are powerful ICs for automotive chassis and safety applications and designs where enhanced motor control capability is required. These scalable Power Architecture® devices are supported by an enablement ecosystem that includes boards, software drivers, operating systems and configuration code to help you quickly implement your designs.

This 32-bit system-on-chip (SoC) automotive microcontroller family is the latest achievement in integrated automotive application controllers. It belongs to an expanding range of automotive-focused products designed to address chassis applications—specifically, electrical hydraulic power steering (EHPS) and electric power steering (EPS)—as well as airbag applications.

This family is one of a series of next-generation integrated automotive microcontrollers based on the Power Architecture technology.

The advanced and cost-efficient host processor core of this automotive controller family complies with the Power Architecture embedded category. It operates at speeds of up to 64 MHz and offers high performance processing optimized for low power consumption. It capitalizes on the available development infrastructure of current Power Architecture devices and is supported with software drivers, operating systems and configuration code to assist with users implementations.
