ADSP-2186NBSTZ-320

Digital Signal Processor Dsp Overview

The ADSP-2186NBSTZ-320 is a member of the Analog Devices ADSP-218xN series, a high-performance DSP microcomputer optimized for digital signal processing. Fabricated in a 0.18 μm CMOS process, it delivers an instruction cycle time of 12.5 ns at 1.8 V, sustaining 80 MIPS performance with single-cycle execution. The device integrates up to 256K bytes of on-chip SRAM, configured as 8K words (24-bit) of program memory and 8K words (16-bit) of data memory. It features a three-bus architecture allowing dual operand fetches, independent ALU, MAC, and shifter units, two serial ports, and flexible I/O supporting 1.8 V, 2.5 V, or 3.3 V operation.

Digital Signal Processor Dsp Feature Summary

• High-speed 12.5 ns instruction cycle time (80 MIPS) using 0.18 μm CMOS technology.
• Integrated memory: 8K words program RAM and 8K words data RAM.
• Three-bus architecture enabling simultaneous instruction fetch and dual operand access.
• Dual synchronous serial ports (SPORTs) with hardware companding and autobuffering.

Digital Signal Processor Dsp Applications

• Digital signal processing applications requiring high throughput and low power.
• Battery-operated portable equipment utilizing power-down modes.
• Systems requiring flexible I/O and external memory interfacing via IDMA/BDMA ports.

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 compatibility with existing design constraints regarding voltage levels and pin configurations before procurement.

Digital Signal Processor Dsp Selection Notes

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

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-218xN series, which shares pin compatibility and code compatibility with the broader ADSP-2100 family. Family members differ primarily in on-chip SRAM size, ranging from 4K to 48K words of program memory.

Digital Signal Processor Dsp Replacement Considerations

Other ADSP-218xN series members (e.g., ADSP-2184N, ADSP-2185N, ADSP-2187N) are pin-compatible alternatives offering different memory sizes. Verify software compatibility and memory usage before substituting.
