PIC18F “K90”, je nová rodina PIC 8-bitových mikrokontrolérov - označených nálepkou "LP", 5V kompatibilitou a na čipe integrovaným LCD radičom a 12-bitovým AD prevodníkom.
Rodina spadá pod technológiu nanoWatt XLP s odberom v sleep režime iba 20nA.

Dodávané budú v 64 a 80 pinových púzdrach, s pamäťovým potenciálom v rozsahu od 32KB do 128KB Flash, až 4 KB RAM a 1 KB EEPROM.
Obsahujú taktiež 24 kanálový mTouch™ blok (kapacitné bezkontaktné snímanie).
