GENERAL DESCRIPTION
The Z87001 /Z87L01 FHSS Cordless Telephone Trans-
ceiver/Controller is expressly designed to implement a 900
MHz frequency hopping spread spectrum cordless tele-
phone 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.
The Z87001 is the ROMless version of the Z87000 Spread
Spectrum Controller IC. Specifically intended to facilitate
user specific software development, the Z87001 can ac-
cess up to 64 kwords of external program ROM.
DS96WRL0800
The Z87001 supports a specific cordless phone system
design that uses frequency hopping and digital modulation
to provide extended range, high voice quality, and low sys-
tem costs.
The Z87001 uses a Zilog 16-bit fixed-point two鈥檚 comple-
ment static CMOS Digital Signal Processor core as the
phone and RF section controller. The Z87001鈥檚 DSP core
processor further supports control of the RF section鈥檚 fre-
quency synthesizer for frequency hopping and the genera-
tion of the control messages needed to coordinate incorpo-
ration of the phone鈥檚 handset and base station. Additional
on-chip transceiver circuitry supports Frequency Shift Key-
ing modulation/demodulation and multiplexing/demulti-
