Texas Instruments has made available four new development kits supporting the fourth generation of its ARM Cortex-M3-based Stellaris MCUs. The new kits allow developers to immediately begin their designs, leveraging the advanced connectivity, data efficiency and motion control features of the newest 32-bit Stellaris MCUs. Further simplifying development, each kit includes the comprehensive StellarisWare peripheral driver library, graphics library, USB library and code examples.
The offering consists of two new evaluation kits, one development kit and one reference design kit. Each contains an 80 MHz Stellaris MCU with 256 KB Flash, 96 KB SRAM, StellarisWare software in ROM, as well as integrated Ethernet, USB on-the-go (OTG)/host/device and CAN.
The LM3S9B90 and LM3S9B92 Ethernet+USB-OTG evaluation kits include an in-circuit debug interface board and the 36 x 102 mm EK-LM3S9B90 or EK-LM3S9B92 evaluation board. For applications requiring power saving modes, the new 80 MHz LM3S9B90 MCU features a hibernation module for extended periods of inactivity. For applications requiring more simultaneous access to peripherals and advanced motion control, the 80 MHz LM3S9B92 MCU features eight PWM outputs for motion and energy and two quadrature encoder input (QEI) modules, along with options for maximum peripheral connectivity. Integrated connectivity peripherals include Ethernet 10/100 with two LED indicators and USB 2.0 full-speed OTG. Complete source code, documentation and a choice of evaluation tools from third party ARM tools vendors are available for simplified development.
The DK-LM3S9B96 development kit features a 3,5” landscape QVGA TFT colour LCD graphics display and a thumbwheel potentiometer for simple menu navigation. The SafeRTOS stored in ROM can be used as a standard operating system or as part of a high integrity application requiring IEC61508 or FDA510(k) certification. The kit features the highly integrated 80 MHz Stellaris LM3S9B96 MCU and two external peripheral interface (EPI) daughter boards – one featuring 8 MB SDR SDRAM memory and one featuring easy access to all 32 EPI pins. It integrates an Interchip Sound (I²S) interface with an external audio codec and interface supporting line in/out, microphone in and headphone out.
The 3,5 inch landscape single board computer intelligent display reference design kit (RDK-IDM-SBC) is an example of a human machine interface (HMI) touch display panel for embedded control devices. It features an 80 MHz LM3S9B92 MCU in addition to extended board-level memories including 8 MB SDRAM, 1 MB serial Flash, USB host connector for external mass storage, and a MicroSD card slot for image, data and code storage. The kit includes a 3,5 inch landscape-oriented QVGA 16-bit colour LCD resistive touch panel display with white LED backlight. Serial, digital and analog connectivity options include 10/100 Ethernet RJ45 Jack, USB 2.0 Type A connector, CAN through a terminal block interface, as well as UART and I²C through an expansion header. An I²S audio codec with power amplifier is included to drive an external 8 Ω speaker.
