GENERAL DESCRIPTION
The Z89323/373/393 DSP family of products builds on
Zilog's first generation Z893XX DSP core, integrating several
peripherals especially well suited for cost-effective voice,
telephony, and control applications.
These DSP devices feature a modified Harvard architecture
supported by one program bus and two on-chip data
buses. This bus structure is supported by two address
generators and six register pointers to ensure that the
20 MIPS DSP CPU is continually active.
The Z893X3 DSP family is designed to provide a complete
DSP and control system on a single chip. By integrating
various peripherals, such as a high-speed 4-channel, 8-bit
A/D, an SPI, three timers with PWM and WDT support, the
Z893X3 family provides a compact system solution and
reduces overall system cost.
To support a wide variety of development needs, the
Z893X3 DSP product family features the cost-effective
Z89323 with 8 Kwords of on-chip ROM, and the Z89373, a
16-MIPS OTP version of the Z89323, ideal for prototypes
and early production builds. For systems requiring more
than 8 Kwords of program memory, the Z89393 device can
address up to 64 Kwords of external program memory.
