MCUs boast lowest sleep current

27 May 2009 DSP, Micros & Memory

Microchip has claimed the world’s lowest sleep current for 8-bit microcontrollers (MCUs). The PIC18F46J11 and PIC18F46J50 feature Microchip’s new nanoWatt XLP eXtreme Low Power technology, which enables typical sleep currents of less than 20 nA. The technology provides multiple internal wake-up sources, such as realtime clock and calendar alarm, brown-out resets, and interrupts and watch-dog timers, all while maintaining I/O states. The general purpose PIC18F46J11 MCUs enable designers to add new features to a variety of applications, while maintaining low power and small size, while the PIC18F46J50 devices include Full Speed USB 2.0 for designs requiring connectivity, for remote field upgrades or the downloading of data. Both families include the mTouch peripheral to enable capacitive touch user interfaces.
