Z89223

The Z89223 is designed as one kind of 16-bit digital signal processors with A/D converter.The design is optimized for processing power with a minimum
of silicon area.The Z89223 16/24-Bit architecture accommodates advanced signal processing algorithms. The operating performance and efficient architecture provide deterministic instruction execution. Compression, filtering, frequency detection, audio, voice detection, speech synthesis, and other vital algorithms can all be implemented.

Some important points can be summarized as:(1)operating range:5V±10%;0°C to 70°C standard temperature,40°C to +85°C extended temperature;(2)DSP core:16-Bit fixed point DSP,24-Bit ALU and accumulator;single-cycle multiply and ALU operations;six-level hardware stack;six data RAM pointers and sixteen program memory pointers;RISC processor with 30 instruction types.On-chip peripherals:4-channel,8-bit half-flash A/D converter;serial peripheral interface (SPI);three general-purpose counter/timers;up to 40 bits of I/O;three vectored interrupts servicing eight sources and low power clock modes with wake-up options.
