Texas Instruments Microcontroller Family Offers Industry-Leading MIPS/Watt Performance for Battery-Powered Applications
DALLAS (June 22, 1998) -- A microcontroller family from Texas Instruments (TI) that provides an ultra-low power solution is now available for the first time outside Europe. These devices offer a high-performance 16-bit reduced instruction set computing (RISC) microcontroller unit (MCU) and integrated peripherals for industry-leading MIPS/Watt performance. This combination is ideal for applications such as utility metering, industrial metering, high-precision portable measurement and home measurement such as thermostats and smoke detectors. Designed in extensively by utilities in Europe, these devices will be especially useful in North America for remote meter reading as utilities are deregulated.
This microcontroller family, designated the MSP430, has lower standby power and lower active power than any other 8 or 16-bit MCU market solution. With a performance rating of 4 MIPs, the MSP430 delivers in an industry leading 1200 MIPS per Watt. Its ultra-low power consumption can extend battery life up to ten times longer than traditional low power MCUs. The devices also offer the industry's shortest active duty cycle.
The MSP430 offers an integrated, high-resolution A/D converter, producing a lower total system cost and reduced power consumption than solutions using a discrete A/D converter. On-chip integration of the 16-bit RISC core, the 14-bit resolution A/D, liquid crystal display (LCD) driver, internal oscillator, universal asynchronous receiver/transmitter (UART/SPI), timers and JTAG make the MSP430 the highest performance, lowest power single-chip solution for most battery-powered applications.
The MSP430 device family is fully supported by a development tool set including a Windows® based software simulator, evaluation boards with assembler and linker, C-compiler with industry-leading efficiency, in-circuit emulators, UV-EPROM devices, programming adapter or gang programmer for OTP devices, and a JTAG tool set for debug.
The MSP430 product family consists of the following devices, available now in the below configurations. In addition, the MSP430C311s -- listed first in the table below -- will be available in third quarter of 1998.
