Luminary Micro Adds New Parts, Packages, and Temperature Grades to the Largest Selection of ARM-based Microcontrollers

    AUSTIN, Texas, Feb. 27 /CNW/ -- Luminary Micro (,
creators of the award-winning Stellaris(R) family of ARM(R)
Cortex(TM)-M3-based microcontrollers (MCUs), today announced the immediate
availability of nineteen new Stellaris family members, providing
cost-effective entry points and precise motion control support. Additionally,
Luminary Micro extends the capability and reach of the entire Stellaris family
by announcing a new small BGA (ball-grid array) package option with a space-
saving 10mm by 10mm footprint and a new extended temperature option with a -40
to 105 degrees Celsius operating temperature range.
    "As ARM's lead partner in the development of the Cortex-M3 core, Luminary
Micro was the first company to bring the ARM Cortex-M3 to market.  With
today's announcement, we have now brought 104 Stellaris ARM Cortex-M3-based
microcontrollers to market in just two years," said Jean Anne Booth, Chief
Marketing Officer of Luminary Micro. "The addition of extended temperature
range and small BGA packages opens up even more opportunities for customers to
add capabilities to their products that were previously out of reach."
    60 Percent Footprint Reduction in 108-BGA Package
    The new 108-BGA packages provide up to a 60% smaller footprint than
current Stellaris-family devices available in a 100-pin LQFP package. This
small 10mm by 10mm package enables the use of fully-featured Stellaris
microcontrollers in designs where board space is limited, such as a motor with
integrated control electronics.
    19 New MCUs Extend the World's Largest Selection of ARM-based MCUs
    Eighteen of the new Stellaris microcontrollers provide capable, cost-
efficient entries into the product family. These include six LM3S300/600/800
low pin count real-time MCU series family members, four LM3S1000 high pin
count real-time MCU series family members, four LM3S2000 CAN-enabled MCU
series family members, and four LM3S6000 Ethernet-enabled MCU series members.
These entry-level MCUs provide single cycle on-chip flash ranging from 16KB to
256KB, single cycle on-chip SRAM ranging from 4KB to 64KB, and include I2Cs,
SPIs, UARTs, up to four flexible 32-bit timers, and up to eight channels of
analog-to-digital conversion.
    Also announced today is the LM3S8971, which provides a new option for
precision motor control, with six motion-control capable PWMs, a CAN 2.0 A/B
controller and an integrated 10/100 Ethernet MAC / PHY.  The recently
announced Brushless DC Motor Control Reference Design Kit (RDK-BLDC) features
the new LM3S8971 and includes four-quadrant motor control for three-phase
brushless DC motors rated at up to 36 V and 60,000 RPM.
    New Extended Temperature Option Extends Operating Range
    Rounding out the capabilities announced today is a new extended
temperature operating range, adding an option for -40 to 105 degree Celsius
extended temperature operating range. Both the new extended temperature grade
and current industrial temperature grade (-40 to 85 degree Celsius) options
are available across the entire Stellaris family of microcontrollers.
    Stellaris Features the Cortex-M3 Core
    The ARM Cortex-M3 processor, the microcontroller member of the ARM Cortex
processor family, is at the heart of all Stellaris microcontrollers. Designed
for serious microcontroller applications, the Cortex-M3 core features highly
deterministic, fast interrupt processing - as low as six cycles and never more
than twelve cycles. At the heart of the Cortex-M3 processor is an advanced 3-
stage pipeline core, based on the Harvard architecture, incorporating features
such as branch speculation, single cycle multiply and hardware divide to
deliver exceptional performance. Cortex-M3 implements the new Thumb(R)-2 mixed
16-/32-bit instruction set architecture without mode switching, helping it to
be 70 percent more efficient per MHz than an ARM7TDMI-S(R) processor executing
Thumb instructions, and 35 percent more efficient than the ARM7TDMI-S
processor executing ARM instructions, for the Dhrystone benchmark.
    The Stellaris microcontroller family features a fully integrated 10/100
Ethernet, up to three integrated Bosch CAN 2.0 A/B controllers, three UARTs,
two I2Cs, and two synchronous serial interfaces (SSI). Stellaris Ethernet-
enabled devices combine both the Media Access Control (MAC) and Physical (PHY)
layers, marking the first time that integrated connectivity is available with
an ARM Cortex-M3 MCU and the only integrated 10/100 Ethernet MAC and PHY
available in an ARM architecture MCU. The integrated Ethernet features
automatic MDI/MDI-X cross-over detection, and several Ethernet-enabled
Stellaris microcontrollers also include hardware-assisted support for
synchronized industrial networks utilizing the IEEE 1588 Precision Time
Protocol (PTP).
    Pricing and Availability
    The new Stellaris MCUs are available now through Luminary Micro's global
sales channel ( and online
( starting at a suggested price of USD 1.75
(10,000 unit quantity).
