ADSP-2186MKST-300

Digital Signal Processor Dsp Overview

The ADSP-2186MKST-300 is a fixed-point digital signal processor from the ADSP-21xx family, fabricated in a high-speed CMOS process. It features a 75 MHz clock rate and a 13.3 ns instruction cycle time, delivering 75 MIPS sustained performance. The device integrates 40 KB of on-chip RAM, configured as 8K words (24-bit) of program memory and 8K words (16-bit) of data memory. It utilizes a three-bus architecture allowing dual operand fetches per cycle and includes independent ALU, MAC, and shifter units. The component operates with a 2.5 V core voltage and supports 2.5 V or 3.3 V I/O levels.

Digital Signal Processor Dsp Feature Summary

• 75 MHz processing speed with single-cycle instruction execution and context switching.
• Integrated 40 KB on-chip RAM (8K x 24-bit Program, 8K x 16-bit Data).
• Three independent computational units: ALU, Multiplier/Accumulator, and Barrel Shifter.
• Dual serial ports (SPORT0/SPORT1) with hardware companding and automatic buffering.

Digital Signal Processor Dsp Applications

• High-speed numeric processing applications requiring low power dissipation.
• Battery-operated portable equipment utilizing power-down modes.
• Systems requiring flexible I/O structures for 2.5 V or 3.3 V operation.
• Digital signal processing tasks compatible with the ADSP-2100 family instruction set.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'KST' against Analog Devices documentation to confirm temperature range and package type, as standard datasheets may list generic variants like LQFP or Mini-BGA without detailed suffix definitions. Ensure compatibility with development tools such as the ADSP-2100 Family Development Software and EZ-KIT Lite platforms for system integration.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring code compatibility with the broader ADSP-2100 family while needing integrated on-chip memory. Consider the 144-ball Mini-BGA or 100-lead LQFP packages based on board space constraints. Evaluate the need for external memory interfaces if the 40 KB internal capacity is insufficient for the target algorithm.

Digital Signal Processor Dsp Part Context

The ADSP-2186M belongs to the ADSP-21xx series of SHARC-compatible processors. It extends the base ADSP-2100 architecture with additional instructions for bit manipulation and multiplication. The device supports ICE-Port emulation for debugging within final systems, distinguishing it from earlier generations that required more complex probe connections.

Digital Signal Processor Dsp Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult Analog Devices for current equivalents or cross-reference with other members of the ADSP-218x family, such as the ADSP-2189M, noting potential differences in pinout or memory configuration.
