ADSP-2186MKSTZ-300

Digital Signal Processor Dsp Overview

The ADSP-2186MKSTZ-300 is a digital signal processor from Analog Devices, part of the ADSP-2100 family. It features an Enhanced Harvard architecture with a 16-bit data bus width and operates at a maximum clock frequency of 75 MHz. The device provides 24 kB of program memory and 16 kB of data RAM. It supports a 2.5 V operating supply voltage and is housed in a 100-lead LQFP package. Key interfaces include two serial ports (SPORTs) and a host port for system integration.

Digital Signal Processor Dsp Feature Summary

• Enhanced Harvard architecture with single-cycle instruction execution and dual operand fetches.
• Integrated 40K bytes of on-chip memory configured as 8K words of 24-bit program RAM and 8K words of 16-bit data RAM.
• Two double-buffered synchronous serial ports (SPORTs) with hardware companding support.
• Supports ICE-Port emulation interface for debugging within final systems.

Digital Signal Processor Dsp Applications

• Digital signal processing applications requiring high-speed numeric processing.
• Battery-operated portable equipment utilizing low power dissipation modes.
• Multimedia entry systems and voice/audio signal processing.
• Industrial control systems using the flexible I/O structure and interrupt capabilities.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KSTZ' against the manufacturer's ordering guide to confirm package type, temperature range, and lead-free compliance status. Ensure the required speed grade matches the 75 MHz specification. Confirm that the 100-lead LQFP package dimensions align with the target PCB footprint requirements.

Digital Signal Processor Dsp Selection Notes

Select this component when a 16-bit fixed-point DSP with integrated memory and serial communication interfaces is required. Consider the 2.5 V core voltage and 3.3 V tolerant I/O levels for system compatibility. Evaluate the need for external memory expansion if the internal 40K byte limit is insufficient for the application code and data storage.

Digital Signal Processor Dsp Part Context

This model belongs to the ADSP-2186M series, which extends the ADSP-2100 base architecture. It integrates computational units including an ALU, multiplier/accumulator, and barrel shifter. The device supports multifunction instructions and zero-overhead looping, optimizing performance for complex signal processing algorithms compared to earlier generations in the family.

Digital Signal Processor Dsp Replacement Considerations

Check the ADSP-2189M datasheet for pin-compatible or functionally similar upgrades within the same family. Verify if alternative speed grades or packages within the ADSP-2186M series meet the specific timing and environmental requirements of the design.
