Data buffer has dual multiplexer
Texas Instruments has introduced the industry's first 0- to 4-Gbps data buffer/signal conditioner with a dual multiplexer.
Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
With the highest level of analogue integration and the industry's lowest power consumption, the MSP430F43x/F44x parts provide complete systems on a chip (SoCs).
The MSP430F43x/F44x devices include up to 60Kbyte Flash, 2Kbyte of RAM, a 160-segment LCD, a 200Ksample/s 12bit ADC, a comparator, two PWM timers, two hardware USARTs, a 16bit hardware multiplier and an onboard supply voltage supervisor to combat brown-out.
The family's patented frequency locked loop enables applications to achieve a phenomenally low average current consumption.

TI adds low-cost and high-integration DSP pair
Texas Instruments has unveiled the latest pair of programmable DSPs in its ultra-power-efficient TMS320C55x family of digital signal processors.
Triple-output power modules shrink ADSL designs
Texas Instruments has unveiled two new triple-output plug-in power solutions for asymmetric digital subscriber line (ADSL) applications.
The MSP430's flexible clock system switches from an ultra-low-power 0.8uA standby mode to high performance processing in less than 6us permitting the MCU to maintain battery saving standby mode up to 1000 times longer than competing MCUs.
The extremely versatile high performance 12bit ADC can be configured and optimised to meet the unique needs of customers' applications.
The eight-channel ADC comes with a built in programmable sample and hold, an on-chip RC oscillator, a temperature sensor, low battery detection, and an auto scan with a 16-word buffer that supports high speed mixed-signal processing.
With the auto scan, the MCU is no longer burdened with servicing the high-speed data conversion.
In addition, the design cycle time is significantly reduced by the MSP430's embedded real-time JTAG emulation, which allows devices to be programmed either in stand-alone sockets or in system via the dedicated JTAG pins.
The entire clock system is driven by a single 32kHz watch crystal, which saves cost and reduces high frequency EMI, eliminating the need for a second high-speed crystal.
Another key advantage of the MSP430 product line is the 16bit RISC CPU resulting in the industry's leading C code efficiency.
Samples of TI's new family of MSP4F43x/F44x are available now, with volume production planned for March 2002.
The devices are packaged in a 100-pin PZ quad flatpack.
Suggested pricing for the MSP430F449 in quantities of 1000 is $7.03.
The Flash emulation tool, the MSP-FET430P440, is a complete integrated development environment available now for just $99.
