ADSP-2189MKST-300

Digital Signal Processor Dsp Overview

The ADSP-2189MKST-300 is a fixed-point digital signal processor from the ADSP-21xx family, fabricated by Analog Devices Inc. It operates at a clock rate of 75 MHz with a 13.3 ns instruction cycle time. The device integrates 192 kB of on-chip RAM, configured as 32K words (24-bit) of program memory and 48K words (16-bit) of data memory. It utilizes the ADSP-2100 base architecture featuring three computational units: an ALU, a MAC, and a shifter. The processor supports dual serial ports, a byte DMA controller, and programmable I/O. It functions within a temperature range of 0°C to 70°C and requires a core voltage of 2.50 V and I/O voltage of 3.30 V.

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified secondary market suppliers. Confirm the specific suffix 'MKST' corresponds to the required package type and temperature grade. Check for obsolescence status, as this model may be discontinued. Ensure compatibility with existing development tools such as the EZ-KIT Lite or ICE-Port emulators for system integration.

Digital Signal Processor Dsp Selection Notes

Select this model when a 75 MHz processing speed and 192 KB of integrated memory are required for DSP algorithms. Consider the 100-lead LQFP package constraints for PCB layout. Evaluate power requirements against the 2.5 V core and 3.3 V I/O specifications. Compare against other ADSP-21xx variants if different memory sizes or package footprints are needed for the target application.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-2189M series, which extends the ADSP-2100 family architecture. It is designed for embedded control and signal processing tasks. The 'MKST' suffix typically denotes a specific thermal and packaging variant within the broader ADSP-2189 product line, intended for industrial or commercial environments.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the ADSP-2189MKCA-300, which shares similar electrical characteristics but may differ in package type. Verify pinout compatibility and software code compatibility before substitution. Other ADSP-21xx processors may require architectural adaptation due to differences in memory mapping or peripheral sets.
