ADSP-2189MKSTZ-300

Digital Signal Processor Dsp Overview

The ADSP-2189MKSTZ-300 is a single-chip microcomputer optimized for digital signal processing, based on the ADSP-2100 family architecture. It integrates 32K words (24-bit) of program RAM and 48K words (16-bit) of data RAM, totaling 192K bytes of on-chip memory. The device features three computational units: an ALU, a multiplier/accumulator (MAC), and a shifter. It operates with a 13.3 ns instruction cycle time at 2.5 volts, delivering 75 MIPS sustained performance. Key interfaces include two serial ports, a 16-bit internal DMA port, and a byte DMA port.

Digital Signal Processor Dsp Feature Summary

• ADSP-2100 base architecture with single-cycle instruction execution and dual operand fetches via 3-bus system.
• Integrated 192K bytes of on-chip RAM: 32K words (24-bit) program memory and 48K words (16-bit) data memory.
• Three independent computational units: ALU, MAC (40-bit accumulation), and barrel shifter.
• Two double-buffered serial ports with hardware companding and automatic data buffering.

Digital Signal Processor Dsp Applications

• Digital signal processing in battery-operated portable equipment utilizing power-down modes.
• High-speed numeric processing applications requiring parallel computation and data movement.
• Systems requiring flexible I/O structures supporting 2.5 V or 3.3 V operation.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix MKSTZ-300 against official Analog Devices documentation to confirm package type, temperature range, and lead-free status. Ensure compatibility with development tools such as the EZ-KIT Lite and ADSP-2100 Family Development Software for system integration.

Digital Signal Processor Dsp Selection Notes

Select this component when code compatibility with the broader ADSP-2100 family is required alongside extended on-chip memory resources. Consider the 100-lead LQFP package constraints and the need for external memory interfaces if on-chip storage is insufficient for application requirements.

Digital Signal Processor Dsp Part Context

This model belongs to the ADSP-2189M series within the ADSP-2100 family. It shares architectural similarities with other members like the ADSP-2181 but offers distinct memory configurations and interface options tailored for specific DSP workloads.

Digital Signal Processor Dsp Replacement Considerations

Consult Analog Devices documentation for verified cross-references. Substitution requires matching the ADSP-2100 base architecture, pinout compatibility, and electrical specifications including voltage levels and instruction cycle times.
