| TI MSP430 MCU First to Break 500 Nano-amp Barrier | |||||
HOUSTON – Continuing to demonstrate its leadership in ultra-low power microcontrollers (MCUs), Texas Instruments Incorporated (TI) announced today that the newest MSP430F20xx low pin-count, ultra-low power MCU series will deliver a 500 nanoamp standby mode utilizing 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. This enables systems such as fire detectors or home thermostats to operate from the same battery for over a decade. The industry leading 500 nanoamp standby is achieved with all device failsafe features active including zero-power brown-out 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. Using no external components, the VLO reduces systems component count and costs as well as reducing space, all critical requirements for portable applications. No Compromise Architecture New MSP430F20xx MCUs offer a flexible clock system that allows fast operation of up to 16 MIPS with no external components using a digitally controlled oscillator (DCO). The DCO is fully programmable up to 16 MHz 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 16 MIPS in less than one micro-second 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 32 kHz crystal and achieve a standby mode of 0.7 microamps. 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 4x4mm 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 analog comparator for very cost sensitive applications, 200 kilosamples per second (KSPS) 10-bit analog to digital converter (ADC) for real-time signal processing or a 16-bit sigma-delta ADC for high-precision systems. All devices include an enhanced watchdog timer for extreme reliability, a multi-function 16-bit timer and in-system programmable flash that provide greater design flexibility and field upgrade capability. With 128B of RAM and a full featured 16-bit 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. Availability and Support 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 is held in November and December in Dallas, Texas, Landshut, Germany, Taiwan as well as China. For more information on the MSP430 ATC, see www.ti.com/atc05. 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.
