ADSP-2186LBST-133

Digital Signal Processor Dsp Overview

The ADSP-2185LBST-133 is a single-chip microcomputer optimized for digital signal processing applications, fabricated in a high-speed, double metal, low power, 0.5 μm CMOS process. It operates with a 30 ns instruction cycle time, delivering 33 MIPS sustained performance. The device integrates 80K bytes of on-chip RAM, configured as 16K words of program memory and 16K words of data memory. Key architectural features include a three-bus architecture allowing dual operand fetches, independent ALU, multiplier/accumulator, and barrel shifter computational units, and two independent data address generators. It supports ADSP-2100 family code compatibility and includes extensive system interface capabilities such as DMA ports and serial communication interfaces.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix LBST-133 against the manufacturer's official documentation to confirm package type, temperature range, and lead-free status. Ensure the source document corresponds to the ADSP-2185 series specifications provided. Confirm availability through authorized Analog Devices distributors or partners.

Digital Signal Processor Dsp Selection Notes

Select this component when ADSP-2100 family code compatibility is required alongside 33 MIPS performance. Consider the 100-lead TQFP package constraints. Evaluate the 80K byte on-chip memory limit against application requirements. Verify that the 30 ns instruction cycle meets the timing demands of the target DSP algorithms.

Digital Signal Processor Dsp Part Context

The ADSP-2185L series consists of single chip microcomputers differentiated by on-chip SRAM amounts while maintaining pin compatibility. The ADSP-2185 specifically provides 80K bytes of RAM. This series is part of the broader ADSP-21xx family, ensuring software portability across members with varying memory capacities.

Digital Signal Processor Dsp Replacement Considerations

Other members of the ADSP-218xL series are pin-compatible and differ primarily in on-chip SRAM capacity. Select an alternative member based on whether higher or lower memory requirements exist for the specific application design.
