ADSP-2181BSZ-133

Digital Signal Processor Dsp Overview

The ADSP-2181BSZ-133 is a single-chip microcomputer optimized for digital signal processing, based on the ADSP-2100 family architecture. It features a 25 ns instruction cycle time derived from a 20 MHz crystal at 5.0 Volts, delivering 40 MIPS sustained performance. The device integrates 80K bytes of on-chip RAM, configured as 16K words (24-bit) of program memory and 16K words (16-bit) of data memory. Key architectural components include independent ALU, MAC, and shifter units, two Data Address Generators (DAGs), and a powerful program sequencer supporting zero-overhead looping.

Digital Signal Processor Dsp Feature Summary

• ADSP-2100 Family Code Compatible with Instruction Set Extensions
• Dual Serial Ports (SPORT0/SPORT1) with Hardware Companding
• 16-Bit Internal DMA Port and Byte DMA Port for External Memory Access
• Low Power Modes: Power-Down, Idle, and Slow Idle

Digital Signal Processor Dsp Applications

• High-speed numeric processing applications
• Battery-operated portable equipment requiring low power consumption
• Systems utilizing parallel peripherals via I/O memory interface

Digital Signal Processor Dsp Procurement Notes

Verify that the 'BSZ' suffix corresponds to the specific temperature range and package variant required for the application. Confirm the '-133' designation aligns with the specified clock frequency capabilities. Ensure compatibility with the 128-lead TQFP or PQFP footprint during PCB layout. Cross-reference the datasheet revision D specifications against current manufacturing standards.

Digital Signal Processor Dsp Selection Notes

Select this component when ADSP-2100 family code compatibility is required alongside integrated on-chip memory. The ADSP-2181 is suitable for designs needing dual serial ports and extensive interrupt handling without external glue logic. Consider the 128-lead package constraints and the availability of development tools like the EZ-KIT Lite for prototyping. Evaluate power requirements against the available low-power modes if battery operation is critical.

Digital Signal Processor Dsp Part Context

The ADSP-2181 belongs to the Analog Devices ADSP-2100 family of DSPs. It extends the base architecture with integrated memory and serial interfaces. This model represents a high-performance solution within the SHARC-compatible lineage, designed for applications demanding single-cycle execution and efficient data addressing through dedicated DAGs.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the ADSP-2100 family should be verified for pin compatibility and memory size. Models such as the ADSP-2186M offer higher integration but may require software adaptation due to architectural differences. Ensure any substitute supports the same 128-lead package and maintains code compatibility with existing ADSP-2100 assembly or C compiler projects.
