MCU from Freescale packs 40V analog and NVM for automotive apps

Freescale Semiconductor has introduced the first single-chip device in its S12 MagniV mixed-signal microcontroller (MCU) family, the S12VR64. The device is designed for use in DC motors for automotive window lift and sunroof applications connected to local interconnect network (LIN) automotive body networks.

The S12VR64 MCU is based on Freescale's LL18UHV technology which uses 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 enabling analog integration on the MCU so developers can connect high-voltage signals and power supplies directly to the MCU in their automotive designs.

The S12VR64 MCU combines the different devices required for relay-driven electric motor control, including the LIN physical layers, voltage regulators and low- and high-side drivers, into one device.

"We are leveraging our automotive semiconductor leadership and proven process technology expertise to create a more efficient solution for networked automotive applications," said Reza Kazerounian, senior vice president and general manager of Freescale's Microcontroller Solutions Group. "The S12VR64 mixed-signal MCU is the first device based on LL18UHV technology, and we'll continue to add products to our S12 MagniV family that offer the right levels of precision and intelligence for a range of motor control and lighting applications in body electronics and other areas of the car."

The S12 MagniV family members include:

o New S12VR64 mixed-signal MCU.

o Existing system-in-package (SiP) solutions (MM912F634, MM912G634, MM912H634).

Freescale is focusing to expand the S12 MagniV family to include a full range of AEC-Q100 qualified products that integrate an MCU, automotive voltage regulators, LIN and CAN physical layers, motor drivers and more in either single-chip or dual-die form, all in single-package solutions. The next parts planned for the S12 MagniV family are single-chip solutions for applications such as brushless DC motor control, LED lighting, stepper motor control, generic LIN slave nodes or a general-purpose MCU combined with high-voltage I/O.

Availability: Now.
Pricing: $1.65 for 10K units.
