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.
