GENERAL DESCRIPTION
The Z87010/Z87L10 is a second generation CMOS Digital
Signal Processor (DSP) that has been ROM-coded by
Zilog to provide full-duplex 32 Kbps, Adaptive Delta Pulse
Code Modulation (ADPCM) speech coding/decoding (CO-
DEC), and interface to the Z87000/Z87L00 Spread Spec-
trum Cordless Telephone Controller. Together the
Z87000/Z87L00 and Z87010/Z87L10 devices support the
implementation of a 900 MHz frequency-hopping spread
spectrum cordless telephone in conformance with United
States FCC regulations for unlicensed operation.
The Z87010 and Z87L10 are distinct 5V and 3.3V versions
of the ADPCM Audio Encoder/Decoder. For the sake of
brevity, all subsequent references to the Z87010 in this
document also are applicable to the Z87L10, unless spe-
cifically noted.
The Z87010’s single cycle instruction execution and Har-
vard bus structure promote efficient algorithm execution.
The processor contains a 4K word program ROM and 512
word data RAM. Six dual operand fetching. Three vectored
interrupts are complemented by a six level stack. The CO-
DEC interface enables high-speed transfer rate to accom-
modate digital audio and voice data. A dedicated
Counter/Timer provides the necessary timing signals for
the CODEC interface. An additional 13-bit timer is dedicat-
ed for general-purpose use.
The Z87010’s circuitry is optimized to accommodate intri-
cate signal processing algorithms and is used here for
speech compression/decompression, generation of DTMF
tones and other cordless telephone functions. Dedicated
hardware allows direct interface to a variety of CODEC
