Luminary Micro Continues Its Leadership With the 4th Generation of Stellaris


AUSTIN, Texas, Mar. 3 /PRNewswire-AsiaNet/ --

          Nine New ARM Cortex-M3-based Microcontrollers Unveiled in Low

                           Power 130nm Technology

    Luminary Micro, creators of the award-winning Stellaris(R) family of ARM(R)

Cortex(TM)-M3-based microcontrollers (MCUs), today announced nine new Stellaris

family members, featuring new combinations of connectivity, memory

configurations, and advanced motion control. Unveiled today are five

microcontrollers in Luminary Micro's new LM3S9000 Series (featuring an on-chip

combination of 10/100 Ethernet MAC/PHY, USB On-The-Go, and Controller Area

Network) and two new microcontrollers each for the LM3S2000 CAN Series and

LM3S5000 USB and CAN Series. The new Stellaris family members further extend the

industry's largest ARM-based microcontroller product line by adding higher

performance with speeds up to 100 MHz and lower operating power with 130nm low

power technology.

    New and Enhanced Stellaris Family Capabilities Enable New Applications

    Today's announcement expands the reach of the innovative Stellaris family

by adding a number of compelling new features, including a versatile External

Peripheral Interface (with modes to support SDRAM, SRAM/Flash, Host-Bus, and

M2M), an Integrated Interchip Sound (I2S) Interface, simultaneous dual ADC

capability, a second watchdog timer with independent clock for safety

critical applications (supported by the recently-announced IEC 60730 library

addition to the StellarisWare(TM) Library), and a 16 MHz software-trimmed 1%

Precision Oscillator.

    In addition, these new products offer valuable enhancements to the

Stellaris family, such as faster ARM Cortex-M3 speed options up to 125 DMIPS

(100 MHz), incorporation of the new ARM Cortex-M3 R2P0 low power core,

extended on-chip software in ROM, increased single-cycle RAM up to 96KB for

data efficiency, and 32 channels of Direct Memory Access (DMA) support

expanded to more peripherals. The Stellaris family's already-speedy UARTs

have been augmented with LIN support, ISO 7816 support, full modem

capability, and increased speeds up to 12.5 Mbps. Embedded programmers will

appreciate the useful new End of Transmission interrupt capabilities on the

enhanced UART and SSI peripherals.

    Leadership in High-Performance, Low-Power Capabilities

    The fourth generation of Stellaris microcontrollers breaks new ground in

high-performance, low-power microcontroller applications. Designers of

low-power systems will benefit from the improved power management resulting

in a 1.5 ms fast wake from hibernate and power-up, as well as significantly

lower power consumption with a range from 4 uA in hibernate mode to a typical

56 mA in run mode. The battery-backed hibernate module includes a very

generous 256 bytes of non-volatile battery-backed memory, along with

low-battery detection, signaling, and interrupt generation. The

microcontroller can quickly wake from hibernate based on the integrated

real-time counter (RTC), an external pin interrupt, or low battery detection.

Software can finely regulate power performance by specific power shutdown of

unused peripheral blocks. To minimize system cost, a single 4 MHz crystal can

be used for both hibernate RTC functions and the main MCU oscillator


    Fast, Flexible External Peripheral Interface Cuts Design Time and


    The External Peripheral Interface (EPI) is a flexible high-speed parallel

bus for external peripherals or memory. The EPI has several modes of

operation providing glueless interface to many types of external devices, and

supports execution of code from external memory. Enhanced capabilities

include direct addressing, DMA support, hard realtime use (no impact on

latency) through non-blocking reads and buffered writes, clocking control,

wait state generation, and stall prevention. The EPI supports x16 SDRAMs up

to 64MB at up to 50 MHz, including automatic refresh and a sleep/standby

mode. The Host-Bus mode provides traditional x8 MCU bus interface

capabilities with up to 24MB of addressing, as well as 8-bit FIFO devices

with support for FIFO full/empty signalling. The machine-to-machine mode

provides wide parallel interfaces for fast communications, with data widths

up to 32 bits and data rates up to 150 MB/s.

    Extended StellarisWare Software Conveniently Stored in ROM

    The StellarisWare Peripheral Driver Library is a royalty-free set of

functions for controlling the peripherals found on the Stellaris family of

ARM Cortex-M3 microcontrollers. Vastly superior to a GUI peripheral

configuration tool, the Stellaris Peripheral Driver Library performs both

peripheral initialization and peripheral control functions with a choice of

polled or interrupt-driven peripheral support. With the Stellaris Peripheral

Driver Library in ROM, it is easier than ever to use the library to quickly

develop efficient and functional applications in an environment where the

entire flash memory is available for use for the application. For complete

flexibility in functionality, the ROM-based Stellaris Peripheral Driver

Library also supports flash-based overrides of standard Stellaris Peripheral

Driver Library functions.

    In addition, the new Stellaris microcontrollers include the StellarisWare

Boot Loader in ROM, allowing users to download code to flash memory for

firmware updates through UART, I2C, SSI, or Ethernet. The newest Stellaris

microcontrollers also include cryptography support with Advanced Encryption

Standard (AES) tables for 128-, 192-, and 256-bit key sizes included in ROM.

Other memory-saving functions provided in ROM include the Cyclic Redundancy

Check (CRC) error detection function.

    Stellaris - the First Microcontroller to Bring Serious Real-time

Industrial Connectivity Capability to the ARM Architecture

    The LM3S9000 Series of ARM Cortex-M3-based Stellaris microcontrollers

feature a fully integrated 10/100 Ethernet MAC plus PHY, USB 2.0 Full Speed

On-the-Go, and integrated Bosch CAN networking technology, the golden

standard in short-haul industrial networks. The LM3S9B95 Stellaris

microcontroller features a 10/100 Ethernet MAC and PHY augmented with

hardware assisted IEEE 1588 Precision Time Protocol (PTP) capability,

enabling synchronization of distributed real-time clocks in a packet-based

multicast network. Together with larger on-chip memories, enhanced power

management, and expanded I/O and control capabilities, the new LM3S9000

Series Stellaris family members are optimized for industrial applications

requiring reliable control and connectivity, including remote monitoring,

electronic point-of-sale machines, test and measurement equipment, network

appliances and switches, factory automation, HVAC and building control,

gaming equipment, motion control, medical instrumentation, and fire and


    Sophisticated Stellaris Motion Control Technology - Accelerating Motor


    The Stellaris Family of ARM Cortex-M3 microcontrollers features IP

especially designed for precision motion control and typically found only on

costly specialty devices, including: eight full channels of PWM control with

dead-band generators providing shoot-through protection for applications such

as 3-phase inverter bridges; four fault-condition handling inputs in hardware

quickly providing low-latency shutdown; synchronization of timers enabling

precise alignment of all edges; and two hardware quadrature encoders enabling

precise positioning sensing. With the new dual ADC units providing

simultaneous ADC measurement capability, Stellaris is the ideal solution for

demanding motion applications that require simultaneous current and voltage

measurements or simultaneous multi-phase measurements, including

sophisticated motor drives for AC Inverters, Brushless DC motors, Stepper

motors, and Brushed DC motors.
