Luminary Micro Continues Its Leadership With the 4th Generation of Stellaris
Microcontrollers
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
function.
Fast, Flexible External Peripheral Interface Cuts Design Time and
Complexity
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
security.
Sophisticated Stellaris Motion Control Technology - Accelerating Motor
Design
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.
