Luminary Micro has released the new Stellaris DK-LM3S9B96 development kit platform in support of the 10 recently-launched Stellaris MCUs. The new development kit provides users access to all the features of the new Stellaris MCUs, including new combinations of connectivity, data efficiency, and advanced motion control.

The development kit enables access to the rich features of the latest Stellaris microcontroller family members including simultaneous interfaces for Ethernet MAC/PHY, USB On-The-Go and CAN. The DK-LM3S9B96 also adds several features that enhances the overall user experience, such as an integrated 3.5-inch color QVGA LCD graphics display with a resistive touch interface, a thumbwheel potentiometer (for menu navigation), a MicroSD card slot, 1Mbyte of serial flash memory, precision 3V analog reference voltage, user LED and pushbutton and I/O wired to convenient break-out pads. Moreover, the DK-LM3S9B96 takes full advantage of the Stellaris family's new versatile External Peripheral Interface with an 8Mbyte SDRAM memory module attachment and the new I?S Interface with an external audio codec and interface supporting line in/out, microphone in, and headphone out.

10-minute promise
The feature-rich DK-LM3S9B96 development kit includes the development board, all required cables, four different evaluation tools suites for popular development tools, documentation, a complete StellarisWare Firmware Development Package, USB flash drive, microSD Card, 8Mbyte SDRAM memory module, and a breakout board for the External Peripheral Interfaceeverything a developer needs to get up and running in 10 minutes or less. The kit spans the design spectrum from evaluation to prototyping to application-specific design by functioning both as a development platform and as a serial in-circuit debug interface for any Stellaris MCU-based target board.

Highly-integrated MCU
The Stellaris DK-LM3S9B96 features the Stellaris LM3S9B96 MCU, based on the new low-power revision of the ARM Cortex-M3 controller core operating at up to 80MHz, with 256Kbyte flash and 96Kbyte SRAM. The device also offers a 32-channel DMA, 32bit external peripheral interface, 16MHz internal 1 percent precision oscillator, on-chip ROM preloaded with the royalty-free StellarisWare Peripheral Driver Library, boot loader, AES encryption lookup tables, CRC function, and the SafeRTOS kernel for general RTOS and safety critical applications.

The LM3S9B96 also features real-time industrial connectivity, with a 10/100 Ethernet MAC/PHY, two CAN controllers, USB 2.0 full speed On-the-Go/host/device, two SSI/SPI controllers, two I?C interfaces, an I?S interface, and three UARTs, as well as hardware-assisted support for synchronized industrial networks utilizing the IEEE 1588 Precision Time Protocol. The LM3S9B96 microcontroller also features advanced motion control features, including 8 motion-control PWM outputs with dead-band timers, two quadrature encoder inputs for precise position monitoring, and 4 fault protection inputs for low-latency shutdown.

In addition, the MCU offers intelligent analog capability, including three analog comparators and 16 channels of highly accurate 10bit A/D conversion, with the ability to sample two channels simultaneously at speeds of 1MSps. The LM3S9B96 MCU also provides 16 digital comparators, a 24bit Systick timer, four 32- or eight 16bit general-purpose timers, two watchdog timers with different clock sources, low drop-out voltage regulator, brown-out reset, power-on reset controller and up to 65 GPIOs.

The new Stellaris DK-LM3S9B96 development kit will be available in late Q2 for $425.
