GENERAL DESCRIPTION
The Z89175/176 is a fully integrated, dual processor con-
troller designed for voice processing applications. The I/O
control processor is a Z8® with 24 KB of program memory,
two 8-bit counter/timers, and up to 47 I/O pins. The DSP is
a 16-bit processor with a 24-bit ALU and accumulator,
512x16 bits of RAM, single cycle instructions, and 8K
words of program ROM. The chip also contains a half-flash
8-bit A/D converter with up to a 16 kHz sample rate and a
10-bit PWM D/A converter. The sampling rates for the con-
verters are programmable. The precision of the 8-bit A/D
can be extended by resampling the data at a lower rate in
software. The Z8 and DSP processors are coupled by
mailbox registers and an interrupt system. DSP or Z8 pro-
grams can be directed by events in each other’s domain.
The Z89176 is the ROMless version of the Z89175. How-
ever, the on-chip DSP is not ROMless.
Notes: All Signals with a preceding front slash, "/", are ac-
tive Low, e.g., B//W (WORD is active Low); /B/W (BYTE is
active Low, only).
