microcontroller family are the low pin count PIC12F(LF)1840 and PIC16F(LF)1847 which have 7 KB and 14 KB of on-chip flash memory and up
to 1 KB RAM.The MCUs feature mTouch capacitive touch-sensing, with the 'LF' versions
featuring eXtreme low power technology, for active currents of less than 40 µA/MHz and sleep currents down to 20 nA.The PIC12F(LF)1840 MCUs are available in 8-pin PDIP, SOIC and 3 mm x 3
mm DFN SOIC packages, for $0.75 each, in 10,000-unit quantities.The PIC16F(LF)1847 MCUs are available in 18-pin PDIP, SOIC, SSOP and 4
mm x 4 mm UQFN packages, for $1.04 each, in 10,000-unit quantities.
