ADSP-2186NKSTZ-320

Digital Signal Processor Dsp Overview

The ADSP-2186NKSTZ-320 is a member of the Analog Devices ADSP-218xN series, fabricated using a 0.18 μm CMOS process. It operates with a 12.5 ns instruction cycle time at 1.8 V, delivering 80 MIPS sustained performance. The device integrates up to 48K words of program RAM and 8K words of data RAM. Key architectural features include a single-cycle execution capability, a three-bus architecture for dual operand fetches, and independent ALU, multiplier/accumulator, and barrel shifter units. It supports flexible I/O levels (1.8 V, 2.5 V, or 3.3 V) and includes two serial ports, DMA controllers, and ICE-Port debugging support.

Digital Signal Processor Dsp Feature Summary

• High-performance DSP core with 12.5 ns instruction cycle and 80 MIPS sustained throughput.
• Integrated memory configuration of 48K words program RAM and 8K words data RAM.
• Three independent computational units: ALU, MAC (40-bit accumulation), and shifter.
• Dual serial ports (SPORT0/SPORT1) with hardware companding and autobuffering.

Digital Signal Processor Dsp Applications

• Digital signal processing applications requiring high code compatibility with the ADSP-2100 family.
• Battery-operated portable equipment utilizing low-power idle and power-down modes.
• Systems requiring flexible I/O interfacing with 1.8 V, 2.5 V, or 3.3 V logic levels.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure that the required on-chip memory size (48K program/8K data) matches the application needs, as other members in the ADSP-218xN series offer different memory configurations.

Digital Signal Processor Dsp Selection Notes

Select this model when 48K words of program memory and 8K words of data memory are sufficient. Compare against other ADSP-218xN variants if larger memory capacities are required. Consider the 100-lead LQFP or 144-ball BGA package options based on board space constraints.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-218xN series, which consists of six pin-compatible microcomputers differentiated by on-chip SRAM amounts. All series members share the same base architecture and instruction set, ensuring code compatibility across the family while allowing design flexibility based on memory requirements.

Digital Signal Processor Dsp Replacement Considerations

Other members of the ADSP-218xN series (e.g., ADSP-2184N, ADSP-2185N, ADSP-2187N) are pin-compatible alternatives. Selection depends on whether the specific memory configuration of the ADSP-2186N is required or if a different memory size is more appropriate for the system design.
