ADSP-2189MKCAZ-300

Digital Signal Processor Dsp Overview

The ADSP-2189MKCAZ-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. The device features three computational units: an ALU, a multiplier/accumulator with 40-bit accumulation, and a barrel shifter. It operates with a 13.3 ns instruction cycle time at 2.5 volts, delivering 75 MIPS sustained performance. Key interfaces include two double-buffered serial ports, a 16-bit internal DMA port, and a byte DMA port.

• High-speed numeric processing applications
• Multiprocessor communication systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix MKCAZ-300 against the manufacturer's official documentation to confirm voltage levels, temperature range, and package type. Ensure compatibility with development tools such as the EZ-KIT Lite or EZ-ICE emulator for debugging. Confirm that the target system supports the required 2.5V core voltage and 2.5V/3.3V I/O interface options defined in the datasheet.

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. The 100-lead LQFP package is suitable for designs needing extensive I/O and flag pins. Consider the power-down modes and low CMOS standby dissipation if battery life is a critical constraint for the application.

Digital Signal Processor Dsp Part Context

This part belongs to the ADSP-2189M series within the Analog Devices ADSP-21xx family. It shares architectural similarities with other members like the ADSP-2181 and ADSP-2185 but offers distinct memory configurations and pinout optimizations. The device is fabricated using high-speed, low-power CMOS technology.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the ADSP-2181, ADSP-2185, and ADSP-2186. Verify pin compatibility and memory size differences before substitution. Cross-model generic features do not guarantee identical electrical specifications or timing requirements.
