ADSP-2187LBSTZ-160

Digital Signal Processor Dsp Overview

The ADSP-2187LBSTZ-160 is a member of the Analog Devices ADSP-218x family, based on the ADSP-2185 architecture. It features a 30 ns instruction cycle time and sustains 33 MIPS performance. The device integrates 80K bytes of on-chip RAM, configured as 16K words (24-bit) program memory and 16K words (16-bit) data memory. It utilizes a three-bus architecture allowing dual operand fetches in every cycle. Key computational units include an independent ALU, multiplier/accumulator, and barrel shifter. The processor supports single-cycle context switching and multifunction instructions.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix LBSTZ-160 against the manufacturer's current production status, as the primary datasheet references the ADSP-2185. Confirm package type and temperature range specifications for the exact part number to ensure compatibility with design requirements.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring code compatibility with the ADSP-2100 family base architecture. Consider the 100-lead TQFP package constraints and the need for external memory interfaces if on-chip storage is insufficient. Evaluate power-down modes for battery-operated portable equipment needs.

Digital Signal Processor Dsp Part Context

This model belongs to the ADSP-218x series, which extends the ADSP-2100 family architecture. It is designed for high-speed numeric processing and digital signal processing applications. The device integrates extensive interrupt capabilities, programmable timers, and flag I/O alongside the core DSP engine.

Digital Signal Processor Dsp Replacement Considerations

The ADSP-2185 serves as the architectural basis. Verify pinout and electrical compatibility if substituting with other ADSP-218x variants. Ensure software tools support the specific instruction set extensions present in this family.
