Xilinx announced availability of the XtremeDSP tools package along with the availability of a XtremeDSP development kit based on the Virtex-5 SXT FPGA platform. The new bundle and kit offerings include new package pricing that makes it easier for algorithm and system developers who use MATLAB to create high-performance DSP systems using Xilinx FPGAs. The individual DSP design tools, System Generator for DSP and AccelDSP continue to be offered individually to accommodate specific needs of customers. The XtremeDSP Development Kit – Virtex-5 DSP Edition comes with the ML506 development board, reference designs, IP cores, cables and XtremeDSP development tools to give users the ability to create DSP and high-speed serial designs utilizing the Virtex-5 DSP48E slices and RocketIO GTP transceivers. A variety of onboard memory and industry-standard connectivity interfaces add to the ML506’s ability to serve as a versatile development platform for applications serving wireless, automotive, medical, defense and other applications. For low-cost applications, developers can use the XtremeDSP Solutions Starter Platform -- Spartan-3A DSP 1800A FPGA Edition that was announced last September.

Pricing and Availability

The AccelDSP synthesis tool and System Generator for DSP are now available as a packaged bundle for $1,495 (DO-DSP-PC) (previously sold separately for $4,995 and $995 respectively.) The individual tools continue to be available separately for $895 and $995 respectively. The XtremeDSP Development Kit – Virtex-5 DSP Edition (DO-V5-DSP-DK-SG-UNI-G) is available now for $1,695.

STMicroelectronics announced a series of digital-output temperature sensors, operating over the -55 to +125 degrees C temperature range. The STxx75 devices are software-compatible drop-in replacements for industry-standard LM75, DS75 and TCN75A parts, and also complement ST’s STLM20 analog temperature sensor, now being used in several mobile phone designs. The digital sensors, in standard 8-lead TSSOP and SO-8 packages, are intended for use in any control application where a processor with an I2C bus/SMBus needs to take action based on an digital reading of the local temperature, or where an alarm or interrupt is required when a preset temperature level is reached. They use a band-gap temperature sensor, with a programmable 9-bit to 12-bit sigma-delta ADC (analog to digital converter) to digitize the temperature reading to a resolution of up to 0.0625 degrees C. The STTS75 devices are factory-calibrated and require no external components.

 

Accuracy is plus or minus 3 degrees over the full -55 to +125 degrees C temperature range, and plus or minus 2 degrees from -25 to +100 degrees C. The sensors are designed for a supply voltage range of 2.7V to 5.5V and have a low operating current of 75uA (typical) at 3.3V. In the power-saving shutdown mode the standby current is a very low 1uA maximum. Power-up defaults enable standalone operation as a thermostat, and both temperature and hysteresis values are programmable. Typical applications include any product with a hard drive – including laptops, servers and some set-top boxes – plus medical equipment, industrial controllers and LCD backlighting. The STTS75 series is available in volume in SO-8 and MSOP8 (TSSOP8) packages, priced at $0.70 in quantities of 1,000. Samples are also readily available.
