Ultra-low power MCUs

23 July 2008 DSP, Micros & Memory

Texas Instruments has announced a new generation of ultra-low power MSP430 microcontrollers, offering low power consumption, 25 MHz peak performance, increased Flash and RAM memory and integrated peripherals such as RF, USB, encryption and LCD interfaces. With as low as 160 μA/MHz active power consumption and 1,5 μA in standby, these MCUs enable longer battery life and the ability to use smaller batteries for portable applications. A wake up time of less than 5 microseconds with full status retention from both standby and sleep modes provides full performance on demand and instant reaction to events like external interrupts. Multichannel direct memory access (DMA) permits data exchange with peripherals while the core remains in low-power modes. A 32-bit RTC with an alarm requires just 1,5 μA of standby current.
