New low-power MCU family from Microchip

22 July 2009 DSP, Micros & Memory

New from Microchip is the PIC24F16KA family of 16-bit microcontrollers (MCUs) with new nanoWatt XLP eXtreme low-power technology, featuring typical sleep currents as low as 20 nA. Low power, combined with integrated EEPROM in a small footprint and low pin-count package makes the four members of the family ideally suited for battery powered, energy harvesting and other power-constrained applications.

The PIC24F16KA’s 20 nA sleep currents are achieved by isolating power to various circuits during sleep, with a fast wake-up time. The new nanoWatt XLP technology gives designers the flexibility to customise their applications for low power consumption through multiple internal wake-up sources, such as realtime clock and calendar alarm, brown-out resets, interrupts and watch-dog timers, all while maintaining the I/O states.

In addition to suiting low-power and space constrained applications, the PIC24F16KA family has high C-code efficiency and 16 MIPS of computational horsepower, which makes it well suited for applications using advanced algorithms. In addition, it features two rail-to-rail comparators and an mTouch capacitive touch sensing peripheral, as well as SPI, I²C and two UART modules for serial communications. Example applications for the new MCUs will cross the medical, industrial and consumer markets.
