Microcontrollers draw only 500nA on
standby
A novel series of low-pin-count ultra-low-power microcontrollers delivers a 500nA standby mode using unique very-low-power oscillator technology.
Continuing to demonstrate its leadership in ultra-low-power microcontrollers, Texas Instruments has revealed that the newest MSP430F20xx low-pin-count ultra-low-power MCU series will deliver a 500nA standby mode using unique very-low-power oscillator (VLO) technology The VLO technology allows the MSP430F20xx MCU to be totally self-clocked in an ultra-low-power standby mode with self-wakeup capability using no external components

A new development tool aids evaluation of the MSP430 MCU architecture and gives experienced developers all the resources they need to complete an entire MSP430F20xx project from start to finish.
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.
This enables systems such as fire detectors or home thermostats to operate from the same battery for over a decade.
The industry leading 500nA standby is achieved with all device failsafe features active including zero-power brownout reset (BOR) allowing both ultra-low-power and extremely reliable systems.
Prior to VLO, designers had been forced to use external crystals or oscillator circuits to achieve ultra-low-power standby.

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.
Using no external components, the VLO reduces systems component count and costs as well as reducing space, all critical requirements for portable applications.
New MSP430F20xx MCUs offer a flexible clock system that allows fast operation of up to 16MIPS with no external components using a digitally controlled oscillator (DCO).
The DCO is fully programmable up to 16MHz and stable over temperature and voltage with the ability to switch from standby to a fully operation in less than one micro-second.
Ultra-low-power standby combined with 16MIPS in less than 1us allows high-performance systems to stay in standby longer allowing applications to conserve power and use smaller, lower cost batteries.
If embedded real-time clock (RTC) function is required the F20xx MCU can also use a common 32kHz crystal and achieve a standby mode of 0.7uA.
All F20xx devices operate from 1.8 to 3.6V allowing direct battery operation and are available in a 14-pin footprint as small as 4 x 4mm with 10 GPIO pins that include programmable pull-up/pull-down resistors that further eliminate external components.
Designers can match their requirements to three pin-compatible F20xx MCU peripheral options that include an analogue comparator for very cost sensitive applications, 200Ksample/s 10bit analogue to digital convertor (ADC) for real-time signal processing or a 16bit sigma-delta ADC for high-precision systems.
All devices include an enhanced watchdog timer for extreme reliability, a multifunction 16bit timer and in-system programmable Flash that provide greater design flexibility and field upgrade capability.
With 128byte of RAM and a full featured 16bit RISC CPU, complete development in C and reuse of existing MSP430 instruction set architecture (ISA) libraries is supported to reduce time to market.
TI's MSP430 broad platform of MCUs answers market demands for ultra-low-power applications including metering, portable instrumentation and intelligent sensing and enables new forms of embedded power supplies including solar, motion and heat.
The MSP430F20xx uses existing MSP430 USB-based tool chains.
TI will showcase the MSP430F20xx as well as other new MSP430 devices for the first time at the Advanced Technical Conference (ATC), the premier event for all MSP430 MCU developers.
The ATC will be held in November and December in Dallas, Texas, Landshut, Germany, Taiwan as well as China.
The MSP430F20x3 and MSP430F20x1 MCUs are sampling now with full production scheduled Q4 2005.
The MSP430F20x2 MCUs will sample Q4 2005 with production early Q1 2006.
