Low-power 8-bit MCU family is feature rich

Microchip » PIC18F "K22"

The PIC18F K22 MCU family of low-power, high-performance 8-bit microcontrollers provide features such as

  • operation from 1.8 to 5.5 V,
  • two SPI/I2C channels,
  • a 10- or 12-bit A/D converter,
  • and peripherals for capacitive touch-sensing.

They also feature

  • 8 to 128 Kbytes of flash,
  • 256 bits to 4 Kbytes of RAM,
  • one to ten PWMs,
  • up to 11 timers,
  • and sleep currents down to 20 nA.

The MCUs are available in PDIP, QFN, SOIC, SSOP, and TQFP packages with 20 to 80 pins. A complete suite of development tools is available including the MPLAB IDE and MPLAB C18 or Hi-Tech C compilers. (From $0.60 ea/high volume — available now.)
