PIC microcontrollers

Microchip has announced a family of 8-bit PIC microcontrollers with nanoWatt XLP technology, enabling low sleep currents.

The PIC18F13K22, PIC18LF13K22, PIC18F14K22 and PIC18LF14K22 (PIC18F1XK22) MCUs are available in 20-pin packages and provide 1.8 to 5.5 V operation, with up to 16 KB flash program memory. The devices have an enhanced peripheral set that includes support for mTouch capacitive touch sensing and are suitable for a variety of general-purpose applications.

nanoWatt XLP technology allows the MCUs to operate longer using less power, or with fewer battery changes, by enabling sleep current of 34 nA, typical at 1.8 V; timer1 oscillator currents of 800 nA, typical at 1.8 V, 32 kHz; and watchdog timer currents of 300 nA, typical at 1.8 V.

Features of the devices include: 64 MHz internal oscillator that reduces the number of external components needed for complete designs; master synchronous serial port with SPI/I2C interface and address masking; 12-channel, 10-bit analog-to-digital converter; S/R-latch module that supports mTouch capacitive touch-sensing (up to four buttons); enhanced capture/compare/pulse-width modulation with steering capabilities; dual rail-to-rail comparators; programmable brown out reset; low-power 1.8 to 5.5 V operation, with full analog peripheral functionality.
