ROMless Spread Spectrum Cordless Phone Controller
plexing of the 32 kbps voice data and 4 kbps command
data between handset and base station. The Z87001 pro-
vides thirty-two I/O pins, including four wake-up inputs and
two CPU interrupt inputs. These programmable I/O pins al-
low a variety of user-determined phone features and board
layout configurations. Additionally, the pins may be used
so that phone features and interfaces are supported by an

optional microcontroller rather than by the Z87001’s DSP
core.
In combination with an RF section designed according to
the system specifications, Zilog’s Z87010/Z87L10 ADPCM
Processor, a standard 8-bit PCM telephone codec and
minimal additional phone circuity, the Z87001 and its em-
bedded software provide a total system solution.
