The KS8701 simplifies implementation of a FLEXTM paging device by interfacing with any of several off-theshelf paging receivers and any of several off-the-shelf host microcontroller/microprocessors. Its primary function is to process information received and demodulated from a FLEX radio paging channel, select messages addres...
