These functions combine with the capabilities of Toshiba’s “Donau-LC” System on Chip (SoC) for consumer digital media applications. Developers can also take advantage of integrated solutions to powerful-but-expected features of modern LCD-IDTVs, including Dolby ProLogic, Virtual Dolby, SRS True Surround and Common Interface, IDE interface for PVR support, and USB2.0 host. The platform is built around the TC90408FG ‘Donau-LC’ digital media SoC, which combines Toshiba’s Media embedded Processor (MeP) architecture with the Toshiba TX49 L3 64-bit embedded RISC processor with unified file system as host. It provides a four-plane video and graphics engine capable of progressive scan conversion with pixel-accurate on screen display (OSD) at panel resolutions up to 1080p (Full-HD panels).
The MeP modules support dual-stream MPEG-2 video decoding as well as three-stream audio decoding to AAC, MPEG and AC-3 standards, allowing developers to quickly implement differentiating features such as audio description or bi-lingual audio decoding. All necessary demodulation circuitry, interfaces and controllers are also integrated on-chip, including an on-board COFDM (coded orthogonal frequency division multiplexer) demodulator for DVB-T applications that meets international specifications including ETSI 300 744 (DVB-T), NORDIG-II, NORDIG-Unified and DTG. The reference platform is offered complete with an optimised PCB design, enabling a compact solution capable of supporting up to 64Mbyte DRAM and up to 16Mbyte NOR Flash.
The Aurora XT middleware stack meets European-wide DTV standards, country- and region-specific profiles and local receiver specifications, and supports multiple languages, Electronic Program Guides (EPGs), parental ratings, channel ordering, sub-titles and software update mechanisms. At the operating system level, the Emerald IDTV reference platform runs on Linux, delivering advantages for developers including a robust and mature kernel, integrated connectivity features and the proven standard Linux file system, as well as royalty free use and the availability of free tool chains.
Hectronic has announced the H6043, a ARM9-based embedded Linux PC board. Measuring 52.5mm x 20mm, it is the smallest Linux computer available today and comes ready-to-run with an open-source Linux Board Support Package (BSP), 32MB LVDRAM, 16MB Flash, SPI and I2C interfaces, GPIO and a USB2.0 port. Other memory configurations can be offered on request. The battery-powered board has an integrated Li-ion battery charger, powered via the USB port, and features a maximum power consumption of 450mA, and typical power consumption of just 100mA. An optional carrier board provides a dual USB host and expansion options include a button interface and an RFID module that connects via the SPI interface. A complementary debug board is available to accelerate development work. Typical applications include sensor control, alarm systems, e-health systems and instrumentation.
Where more design flexibility and connectivity is needed, Hectronic offers the H6042. This credit card sized board (55mm x 70mm) includes an ARM processor running Linux and a Xilinx Spartan 3E Flash FPGA. The H6042 allows developers to focus on application development by quickly defining the hardware requirements using the FPGA. This reduces development time and time to market.
The compact board is designed to dock onto carrier boards and a selection of interface adapters is available. Based on a 200 MHz Atmel91RM9200 processor, the board’s peripheral functions include 10/100 Mbit Ethernet, four serial ports, SPI and I2C interfaces, FPGA expansion ports, dual host USB ports and a USB device port. The H6042 has a flexible memory sub-system with 32MB Flash and 32MB SDRAM as standard configuration, other configurations can be offered on request. The H6090 development carrier board, that includes a variety of standard interface connectors for system integration, is also available. Hectronic supports both boards with free development tools, drivers, code examples and a complete, open source operating system as part of its Linux BSP.
Both modules are available now. For 100+ quantities, the H6043 costs from 99 USD each and the H6042 from 223 USD each. The H6042 pricing is with the Spartan 3E/500 on board.
The LTC2910 monitors eight low voltage adjustable UV inputs and the LTC2914 monitors four adjustable inputs for OV, UV or negative voltages. Both the LTC2910 and LTC2914 draw just 70uA and are available in 16-lead SSOP and 5mm x 3mm DFN packages. The LTC2913 monitors two input channels for OV and UV conditions, draws only 60uA, and is offered in 10-lead MSOP and 3mm x 3mm DFN packages. The LTC2912 monitors a single supply for OV and UV conditions, with only 40uA of supply current, and is offered in 8-lead TSOT and 3mm x 2mm DFN packages. The LTC2910, LTC2912, LTC2913, and LTC2914 automotive grade voltage monitors are all available today. Pricing begins at $1.97 for 1,000-piece quantities.
