GENERAL DESCRIPTION
The Z893x3 products are high-performance Digital Signal
Processors (DSP) with a modified Harvard architecture fea-
turing separate program and dual data memory banks. The
design is optimized for processing power with a minimum
of silicon area.
The Z893x3 16/24-Bit architecture accommodates ad-
vanced signal processing algorithms. The operating perfor-
mance and efficient architecture provide deterministic in-
struction execution. Compression, filtering, frequency
detection, audio, voice detection, speech synthesis, and oth-
er vital algorithms can all be implemented.
Six data RAM pointers provide circular buffer capabilities
and simultaneous dual operand fetching. Three vectored in-
terrupts are complemented by a six-level stack.
By integrating a high-speed 4-channel, 8-bit A/D, SPI, three
Counter/Timers with PWM and WDT support, and up to 40
bits of I/O, the Z893x3 family provides a compact low-cost
system solution.
To support a wide variety of development requirements, the
Z893x3 DSP product family features the cost-effective
Z89223/323 with 8 KWords of ROM. The Z89273/373, an
