ADSP-2183KST-133

Digital Signal Processor Dsp Overview

The ADSP-2183KST-133 is a single-chip microcomputer optimized for digital signal processing, based on the ADSP-2100 family architecture. It integrates 80 KB of on-chip RAM configured as 16K words (24-bit) of program memory and 16K words (16-bit) of data memory. The processor features a 19 ns instruction cycle time derived from a 26.32 MHz crystal, delivering 52 MIPS sustained performance. 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

• High-performance fixed-point DSP with 52 MIPS sustained execution at 19 ns instruction cycles.
• Integrated 80 KB on-chip RAM: 16K words program memory and 16K words data memory.
• Dual serial ports (SPORT0/SPORT1) with hardware companding and automatic data buffering.
• Supports glueless system design via programmable wait states and separate I/O memory space.

Digital Signal Processor Dsp Applications

• High-speed numeric processing applications requiring fixed-point computation.
• Battery-operated portable equipment utilizing low-power idle and power-down modes.
• Systems requiring transparent program/data transfers via Byte DMA or internal DMA ports.

Digital Signal Processor Dsp Procurement Notes

Verify package availability for the 128-lead LQFP or 144-Ball Mini-BGA configurations. Confirm that the specific suffix KST-133 aligns with the required temperature range and speed grade as defined in the official Analog Devices datasheet. Ensure development tools such as VisualDSP++ are compatible with the ADSP-2100 family instruction set extensions.

Digital Signal Processor Dsp Selection Notes

Select this processor when code compatibility with the broader ADSP-2100 family is required alongside integrated memory and I/O. The device supports new instructions including bit manipulations and x-squared multiplication. Consider the 19 ns cycle time constraint relative to the external clock source; a 26.32 MHz crystal yields the specified performance. Evaluate power requirements against the available Idle and Power-Down modes for battery-sensitive designs.

Digital Signal Processor Dsp Part Context

The ADSP-2183 belongs to the ADSP-2100 family of SHARC-compatible processors. It extends the base architecture with additional integration, including dual serial ports and extensive on-chip memory, reducing the need for external glue logic. This family is designed for high-throughput digital signal processing tasks where deterministic single-cycle instruction execution is critical.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements within the same pinout and feature set are not explicitly listed in the provided documentation. For upgrades, consider other members of the ADSP-2100 family or the SHARC series, noting that instruction set extensions and memory sizes may vary. Verify software compatibility and peripheral mapping before substituting.
