Product Summary

The ADSP-2185NKSTZ-320 consists of six single chip microcomputers optimized for digital signal processing applications. The high-level block diagram for the ADSP-2185NKSTZ-320 appears on the previous page. The ADSP-2185NKSTZ-320 is pin-compatible and is differentiated solely by the amount of on-chip SRAM. This feature, combined with ADSP-2185NKSTZ-320 code compatibility, provides a great deal of flexibility in the design decision. ADSP-2185NKSTZ-320 combines the ADSP-2100 family base architecture (three computational units, data address generators, and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, extensive interrupt capabilities, and on-chip program and data memory.
