GENERAL DESCRIPTION
Zilog's Digital Voice Processor Controller family
combines a Z8® microcontroller and a DSP processor
on-chip for a cost-effective turnkey system in digital
telephone answering devices and other voice processing
applications.
The dual-processor architecture is loosely coupled by
mailbox registers and an interrupt system, enabling DSP or
Z8 programs to be directed by events in each other's
domain.
The Z8 microcontroller uses an expanded register file to
allow access to register-mapped peripheral and I/O
circuits for programming versatility.
The 16-bit DSP processor features a 24-bit ALU and
accumulator with single-cycle instructions, providing the
algorithm processing power necessary for telephone voice
quality.
The Z89165/166 devices offer a half-flash 8-bit A/D
converter with up to 128 kHz sample rate and a 10-bit
Pulse-Width modulator (PWM) D/A converter, eliminating
the need for an external CODEC.
The Z89167/168/169 devices feature a hardware ARAM
interface, as well as a dual-CODEC interface. A 10-bit
PWM D/A converter is also on-chip.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.:
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
