DALLAS -- Texas Instruments Inc. today claimed it has broken the 1-microampere barrier in a low-power 16-bit microcontroller, which integrates mixed-signal functions and flash memory for embedded display applications in utility metering, portable instruments, intelligent sensing, and other systems.
TI said the RISC-based MSP430F43x/F44x microcontroller has the highest level of analog integration and lowest power consumption of any 16-bit MCU. It also has 60 kilobytes of flash, 2 Kbytes of RAM, a 160-segment LCD circuit, 200-kilobit-per-second 12-bit analog-to-digital converter, a comparator, two PWM timers, and other on-board functions.
The microcontroller's clock system switches from a 0.8-microamp standby mode to high-performance processing in less than 6 microseconds, which allows the chip to stay in a battery-saving standby mode up to 1,000 times longer than competing parts, TI said.
Samples of the 16-bit microcontroller are available now with volume production slated to start in March. The chip is packaged in a 100-pin PZ quad flat pack (QFP). Suggested pricing for the MSP430F449 is $7.03 each in quantities of 1,000 is $7.03. TI is also offering a flash emulation tool with an integrated development environment for $99.
