Freescale Adds Industry’s First Single-Chip Automotive Instrument Cluster Solution to S12 MagniV Portfolio mixed-signal microcontroller family offers extreme integration and significant cost savings

Freescale Semiconductor is adding a device family designed primarily for the mainstream automotive instrument cluster market to its S12 MagniV mixed-signal microcontroller (MCU) portfolio. The new S12 MagniV S12ZVH enables developers to create a comprehensive instrument cluster solution with a single chip, significantly reducing time to market and the overall bill of materials.

The S12ZVH 16-bit mixed-signal MCU family is based on Freescale’s LL18UHV technology, which enables extensive analog integration on the MCU 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 S12ZVH, developers also can minimize sourcing from multiple suppliers and improve overall system reliability.

“With our S12ZVH mixed-signal MCU family, Freescale is the first to market with a single-chip solution for automotive instrument clusters,” said Ray Cornyn, vice president of automotive microcontrollers at Freescale. “These highly integrated devices enable streamlined design, making them ideal for entry-level cluster applications in which cost and board space are key drivers.”

The S12ZVH is the first family in Freescale’s S12 MagniV portfolio designed specifically for instrument clusters. The mixed-signal MCUs are 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 S12ZVH MCU platform, including familiar S12 MCU family features such as low power consumption and smart peripherals as well as features such as a CAN physical interface, a 5V regulator system to supply the MCU, a real-time clock and sound generator. Features unique to the S12ZVH family include 8K of ECC RAM and stepper stall detection capability.

S12Z core improvements
The S12ZVH features an enhanced S12Z core that provides significant design benefits compared to prior versions. The addressing space is now linear (no memory paging required), simplifying software development and allowing it to easily port across applications. The efficiency of this new core allows code density improvement up to 40 percent, as well as faster execution than earlier 16-bit architectures.

Benefits of LL18UHV technology
Traditionally, automotive electronic designs have required multiple devices: some created with a high-voltage process to connect to the battery and power actuator outputs, as well as microcontrollers created with a low-voltage digital logic process.
LL18UHV technology uses Freescale’s proven, low-leakage 0.18 micron (LL18) fabrication process to integrate 40V analog, non-volatile memory (NVM) and digital logic on a single piece of silicon. The result is a compact and cost-effective solution that does what it takes up to four chips to accomplish in current designs. Fewer components increase overall quality, allow customers to create a smaller board and ultimately reduce the weight of the automobile.

Enablement
For the S12ZVH family, Freescale plans to offer development tools and software common to existing S12 MCUs, including a cost effective development system, compilers from Cosmic and the CodeWarrior IDE and debuggers. Example code and application notes are expected to be available later this year to help customers speed their development time.
A hardware reference design with comprehensive reference software is expected to be available later this year, providing full BOMs, schematics and documentation that will allow them to easily build their own instrument clusters.
