Freescale Semiconductor unveils the S12 MagniV S12ZVHY MCU family said to provide a comprehensive instrument cluster solution with a single chip, significantly reducing time to market and the overall bill of materials.

 S12 MagniV S12ZVHY MCU

The S12ZVHY mixed-signal MCU family integrates extensive analogue capability so automotive developers can connect high-voltage signals and power supplies directly to the MCU, helping save board space and reduce system complexity. By designing with the S12ZVHY MCU family, developers also can minimise sourcing from multiple suppliers and improve overall system reliability, said the company.

The S12 MagniV S12ZVHY portfolio is targeted at instrument cluster applications requiring controller area network (CAN) connectivity, stepper motor gauges and segment LCD or dot-matrix displays. Customers building an efficient instrument cluster solution can benefit from the integration provided by the S12ZVHY MCU platform, including familiar S12 MCU family features such as low power consumption and smart peripherals as well as features such as a CAN module, a built-in voltage regulator, a real-time clock and sound generator. Features unique to the S12ZVHY family include 4K of ECC RAM and stepper stall detection capability.

The S12ZVHY family is an extension of the current S12ZVH family, allowing hardware and software reuse between platforms through pin compatibility and common S12Z cores, peripherals and software. If customers developing on the current S12ZVH platform are looking for fewer features, the S12ZVHY family is ideal, providing further cost optimisation and no major design modifications needed, said the company. Customers can seamlessly transfer their current S12ZVH development to the S12ZVHY platform.

For the S12ZVHY family, Freescale offers development tools and software common to existing S12 MCUs, including a cost-effective development system, compilers from Cosmic and the CodeWarrior IDE and debuggers. Customers can begin development immediately with the current S12ZVH reference design, which provides schematics and documentation that will allow them to easily build their own instrument clusters and migrate seamlessly to the S12ZVHY reference design planned for later this year.

Limited availability of the S12ZVHY reference design and MCU samples are planned for Q4 of this year. However, customers can start development today with the compatible S12ZVH family.
