GENERAL DESCRIPTION
The Z89175/176 is a fully integrated, dual processor controller 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 converters 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 programs can be directed by events in each other’s domain.
The Z89176 is the ROMless version of the Z89175. However, 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).

GENERAL DESCRIPTION (Continued)
Z8 Core Processor
The on-chip Z8 is Zilog’s 8-bit microcontroller core with an
Expanded Register File to allow access to registermapped peripheral and I/O circuits. The Z8 offers a flexible
I/O scheme, an efficient register and address space structure and a number of ancillary features which makes it ideally suited for high-volume processing, peripheral controllers and consumer applications.
For applications demanding powerful I/O capabilities, the
Z89175 provides 47 pins dedicated to input and output.
These I/O lines are grouped into six ports. Each port is
configurable under software control to provide timing, status signals and parallel I/O with or without handshake.
Four basic memory resources for the Z8 are available to
support a wide range of configurations: Program Memory,
Register File, Data Memory, and Expanded Register File.
The Z8 core processor is supported by an efficient register
file that allows any of 256 on-board data and control registers to be either the source and/or the destination of almost
any instruction. This unique architecture eliminates traditional microprocessor Accumulator bottlenecks and permits rapid content switching.
The Register File is composed of 236 bytes of general-purpose registers, four I/O port registers, and 15 control and
status registers. The Expanded Register File consists of
mailbox registers, WDT mode register, DSP Control register, Stop-Mode Recovery register, Port Configuration register, and the control and data registers for Port 4 and Port
5. Some of these registers are shared with the DSP.
To unburden the software from supporting real-time prob-
lems such as counting/timing and data communication, the
Z8 offers two on-chip counter/timers with a large number
of user-selectable modes.
Watch-Dog Timer and Stop-Mode Recovery features are
software driven by setting specific bits in control registers.
STOP and HALT instructions support reduced power operation. The low-power Stop Mode allows parameter information to be stored in the register file if power fails. An external capacitor or battery will retain device memory and
power the 32 kHz timer.
DSP Coprocessor
The DSP coprocessor is a second generation, 16-bit two’s
complement CMOS Digital Signal Processor (DSP). Most
instructions, including multiply and accumulate, are accomplished in a single clock cycle. The processor contains
two on-chip data RAM blocks of 256 words, a 8K word program ROM, 24-bit ALU, 16x16 multiplier, 24-bit Accumulator, shifter, six-level stack, three vectored interrupts and
two inputs for conditional program jumps. Each RAM block
contains a set of four pointers which can be incremented
or decremented automatically to affect hardware looping
without software overhead. The data RAMs can be simultaneously addressed and loaded to the multiplier for a true
single-cycle scalar multiply.
Four external DSP registers are mapped into the expanded register file of the Z8. Communication between the Z8
and the DSP occurs through those common registers
which form the mailbox registers.
The analog output is generated by a 10-bit resolution
Pulse Width Modulator. The PWM output is a digital signal
with CMOS output levels. The output signal has a resolution of 1 in 1024 with a sampling rate of 16 kHz (XTAL =
20.48 MHz). The sampling rate can be changed under
software control and can be set at 10 and 16 kHz. The dynamic range of the PWM is from 0 to 4V.
An 8-bit resolution half-flash A/D converter is provided.
The conversion is conducted with a sampling frequency of
16 kHz. (XTAL = 20.48 MHz) in order to provide oversampling. The input signal is 4V peak to peak.
Two additional timers (Timer2 and Timer3) have been
added to support different sampling rates for the A/D and
D/A converters. These timers are free-running counters
that divide the crystal frequency to the appropriate sampling of frequency. Two DSP I/O pins: DSP0, DSP1 are
provided for application.

This is a stress rating only; operation of the device at any
condition above those indicated in the operational sections
of these specifications is not implied. Exposure to absolute
maximum rating conditions for an extended period can affect device reliability.
