GENERAL DESCRIPTION

The Z87001 /Z87L01 FHSS Cordless Telephone Transceiver/Controller is expressly designed to implement a 900 MHz frequency hopping spread spectrum cordless telephone compliant with US FCC regulations for unlicensed operation. The Z87001 and Z87L01 are distinct 5V and 3.3V versions, respectively, of the core device. For the sake of brevity, all subsequent references to the Z87001 in this document also apply to the Z87L01 unless specifically noted.
