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.
The newest MSP430 family members include the MSP430F122 with 4Kbyte of ultra-low-power Flash memory and the MSP430F123 with 8Kbyte, which are sampling now.
Both devices include a flexible USART serial port, 16bit PWM timer, analogue comparator, multi-oscillator asynchronous clock system, 22 digital I/Os and a watchdog, and are fully code compatible with all MSP430 devices.
Designers of portable equipment also benefit from the small 28-pin footprint of the new MSP430F12x devices.

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.
Devices in the MSP430F12x family typically consume less than 1uA of current, in stand-by mode with an active 32kHz crystal oscillator and timer.
The family's digitally controlled oscillator provides a system wake-up with a stable high-speed system clock in less than 6us, enabling the applications to remain in battery saving stand-by mode up to 1000 times longer than other competing MCUs.
When active, the new MCUs consume less than 250uA per MIP.
Using the dual clock approach, a single 32kHz watch crystal combined with the integrated DCO can drive the entire system, saving power, cost and reducing high frequency EMI by eliminating a second high-speed crystal.
Due to their low power consumption, MSP430s are ideal for applications that require extended battery life.
For example, a typical MSP430-based fire detection system can run off of the same lithium battery for more than 10 years.
Additional MSP430F12x 28-pin and MSP430F11x 20-pin family members offering high-speed data convertors and highly integrated MSP430F4xx family members are planned for introduction in late 2001 and throughout 2002.
MSP430F12x developers are fully supported today using the MSP-FET430P120 Flash Emulation Tool (FET).
The FET is a modern integrated development environment (IDE) enabling sophisticated real-time in-system emulation using a standard IEEE 1149.1 JTAG interface.
Included with the FET is an unlimited assembler/linker, debugger, software simulator and improved 2Kbyte IAR Kickstart C-compiler.
Also included are a target board and two MSP430F123 evaluation devices.
The MSP430F122 and MSP430F123 come in a 28-pin SOPs and TSSOPs.
Suggested resale pricing in quantities of 10,000 is $2.39 for the MSP430F122 and $2.51 for the MSP430F123.
The MSP-FET430P120 development tool is available now for $99.
