Dallas - Texas Instruments Inc. has added two 16-bit RISC flash microcontroller families to its MSP430 product line. With power consumption below 1 microamp, the MSP430F43x and F-44x target battery-powered system-on-chip applications such as utility metering, portable instrumentation and intelligent sensing.
The MCUs include up to 60 kbytes of flash, 2 kbytes of RAM and a 160-segment liquid-crystal display. They also include an eight-channel, 200-ksample/second, 12-bit analog-to-digital converter, a comparator, two pulse-width-modulator timers and a 16-bit hardware multiplier.
The devices' clock system switches from a 0.8-microamps standby mode to high-performance processing in less than 6 microseconds, thus permitting the MCU to maintain its battery-saving standby mode up to 1,000 times longer than competing MCUs, TI said.
The clock system is driven by a 32-kHz watch crystal that reduces high-frequency EMI.
The MCUs, sampling now with volume production slated for March, come in a 100-pin PZ quad flat pack. The MSP430F449 sells for $7.03 in lots of 1,000. A flash emulation tool, MSP-FET430P440, provides an integrated development environment for $99.
