Motorola Combines Flash MCUs with Analog ICs
for Automotive Applications
New Devices Integrate Control
And Power Functions To Help Reduce Components And Costs In LIN
SystemsMUNICH - September 24, 2003 - As
the Local Interconnect Network (LIN) protocol, a low-cost serial communication
system for vehicles, gains acceptance by automakers worldwide, demand is
increasing for LIN enabled products. Motorola, Inc.'s (NYSE:MOT) Semiconductor
Products Sector is addressing this market requirement with a new series of
devices that combine high-performance flash microcontrollers (MCUs) with
SMARTMOS™ analog integrated circuits (ICs) in a single package.
Many of today's LIN systems include a variety
of different ICs and numerous discrete components. Motorola's new MM908E624 and
MM908E625 Intelligent Distributed Control devices integrate virtually all of the
features needed for a LIN node into a single 54-lead SOIC (small outline
integrated circuit) package. These devices are designed to help automotive
suppliers incorporate power and control functions into systems such as seat,
mirror and window lift controls, door locks and other automotive
electronics.
Communication, Intelligence and
Power in One Small PackageFor communication,
Motorola's MM908E624 and MM908E625 devices include the LIN physical layer
coupled with a flash MCU that integrates an enhanced serial communications
Interface for simple yet flexible management of the LIN protocol. In addition,
a special internal oscillator module in the MCU, called an internal clock
generator, eliminates the need for an external quartz oscillator.
The HC908 microcontroller provides
intelligence for demanding motion control decisions while its flash memory
enables on-the-fly programming and production flexibility. Additional MCU
features include dual timer channels, a 10-bit analog-to-digital converter and
serial peripheral interface.
The analog ICs
on the MM908E624 and the MM908E625 are manufactured using Motorola's proprietary
SMARTMOS process. This enables the combination of high-density/high-speed logic
with precision analog and high-voltage/high-current power circuitry.
The MM908E624 includes the drivers and inputs
necessary for high-current DC motor control using low-cost relays. Its analog
IC features include three high-side outputs that allow direct control of
automotive relays with a minimal number of external components.
With an analog IC that features four
half-bridges and one high-side output, the MM908E625 allows for direct control
of the motors used in door locks and other small motor control applications. In
addition to running DC motors, the MM908E625 can be configured to run bipolar
stepper motors in current control mode up to 500mA in
size.
The analog ICs on both Intelligent
Distributed Control devices also incorporate a watchdog timer and an advanced
voltage regulator with the capability to enter a battery-saving low-power mode
with system wake up via LIN or external inputs.
Development Support, Price and
AvailabilityDevelopment support is offered
with the LIN development kits, which are PC-interface boards combined with
individual device evaluation boards. They allow users to program/debug software
for the MM908Exxx product family and then to control the programmed device using
a LIN master GUI. The kit includes a software monitor interface for the HC08
architecture, the MON08, to enable programming and debugging of MM908Exxx
products. This debug tool allows flash programming and software debugging of
all HC908 Flash MCUs. The kit is supported by most HC08 programming/ debugging
utilities, including Metrowerks CodeWarrior™ for HC08, which is available
separately.
Sample quantities of both of the
new Intelligent Distributed Control devices for LIN are currently available,
with production quantities expected to be available in first quarter of 2004.
The suggested list prices (USD) for 10,000-piece quantities are $3.95 for the
MM908E624 and $4.95 for the MM908E625.
The
evaluation kits, KIT908EINTFCEVB, KIT908E624DWBEVM and KIT908E625DWBEVM, are
each available now for a suggested list price of $100.00
(USD).
About the LIN Consortium
The LIN Consortium was initiated in 1998 as a
group of seven companies focused on developing the LIN specification as a
low-end multiplex solution to complement the Controller Area Network (CAN)
protocol, while reducing the development, production and servicing of automotive
electronics. The Consortium has evolved to today's 35 members - the original
seven Steering Group members and 28 Associated members - made up of leaders in
the automotive, semiconductor and communications sectors. Steering Group members
include Audi, BMW AG, DaimlerChrysler, Motorola Inc., Volvo Car Corporation,
Volkswagen and Volcano Communications Technologies AB (VCT). Since the release
of the first documents in July 1999, the Consortium has disseminated the
specification more than 10,000 times to industrial parties worldwide with the
first LIN-based applications appearing in production vehicles in
2001.
