new products Luminary adds 34 Stellaris MCUs Luminary Micro has introduced 34 new Stellaris microcontrollers (MCUs), adding networking and expanded control capabilities for realtime applications in motion control, ﬁre and security, remote sensing, HVAC and building controls, power and energy monitoring and conversion, network appliances and switches, factory automation, electronic pointof-sale machines, test and measurement equipment, medical instrumentation, and gaming equipment. The additions include 20 members of the Stellaris LM3S1000 high pin count real-time MCU series, 11 members of the Stellaris LM3S8000 Ethernet+CAN internetworking series, and 3 new members of the Stellaris LM3S6000 Ethernet series featuring hardware assist for IEEE 1588 Precision Time Protocol (PTP) support. The LM3S1000 series feature new combinations of expanded general purpose I/O, larger on-chip memory, and low-power optimization for batterybacked applications. The LM3S8000 devices combine both Ethernet Media Access Control (MAC) and Physical (PHY) layers with up to 3 CAN interfaces on-chip, marking the ﬁrst time that integrated internetworking connectivity is available with an ARM Cortex-M3 MCU. Stellaris family MCUs are based on the ARM Cortex-M3 processor, the microcontroller member of the ARM Cortex processor family. Three of the new Stellaris LM3S6000 Ethernet series MCUs and six of the new Stellaris LM3S8000 Ethernet+CAN internetworking MCUs feature hardware assist for IEEE 1588 PTP support. The IEEE 1588 standard provides a mechanism for synchronising distributed real-time clocks in a packet-based multicast network such as Ethernet. Time-based synchronisation is the preferred method for synchronizing control systems (especially motion control) over networks because it is not as susceptible to jitter as other synchronisation methods and is also based on absolute time, making it easier to program. Additional beneﬁts of this standard include the use of inexpensive network components, fault tolerance, hot plugging capability, and self-conﬁguration. Networked variable frequency drives require synchronisation accuracy in the tens of milliseconds, and servocontrolled systems require accuracy in the few hundreds of nanoseconds. Eleven of the new MCUs feature both on-chip Ethernet MAC and PHY and up to 3 integrated CAN controllers, making Stellaris the only ARM-based MCU to offer this useful combination for real-time internetworking applications. With Ethernet features including 10/100 Mbps full and half-duplex operation, automatic MDI/MDI-X crossover correction, programmable MAC address, promiscuous mode support, and generous single-cycle 2kbyte transmit and 2kbyte receive buffers, and Bosch-licensed CAN controllers featuring bit rates up to 1 Mbps, 32 message objects per controller, and automatic transmission disable for TTCAN (timetriggered communication on CAN), the powerful communications capabilities in the LM3S8000 series offermore options for both control and internetworking applications. Two complete evaluation kits are available, the Stellaris LM3S1968 EvaluationKit and the Stellaris LM3S8962 Ethernet+CAN Evaluation Kit. Each includes evaluation boards, all required cables, a choice of evaluation tools suites for popular development tools, documentation, the Stellaris Peripheral Driver Library (providing a convenient, no-hassle method of initializing, programming, and controlling peripherals), applications notes, and everything a developer needs to get up and running in 10 minutes or less. www.luminarymicro.com 39 Board eases STM32 evaluation The Keil MCBSTM32 evaluation board provides access to all functions provided by the STM32 microcontroller family from ST Microelectronics. The board provides interfaces to most on-chip peripherals of the STRM32F103 including UART, CAN, USB, and SPI with SD memory card connector. It is equipped with an LCD, potentiometer, and several LEDs which simpliﬁes software testing. The board comes with an evaluation version of the RealView microcontroller development kit, a complete software development environment for ARM Microcontrollers which in- cludes the RealView C/C++ compiler, the genuine µVision IDE/Debugger, and the RTX RTOS kernel. Also included are several examples for the STM32 microcontroller. www.keil.com www.embedded.com/europe | embedded systems design europe | OCTOBER 2007 039_ESDE.indd 39 11/10/07 11:01:59 http://www.luminarymicro.com http://www.keil.com http://www.embedded.com/europe
