ADSP-2183KSTZ-160

Digital Signal Processor Dsp Overview

The ADSP-2183KSTZ-160 is a single-chip microcomputer optimized for digital signal processing, based on the ADSP-2100 family architecture. It features a 19 ns instruction cycle time at 3.3 Volts, delivering 52 MIPS sustained performance with single-cycle instruction execution and context switching. 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 Architecture: Combines three computational units (ALU, MAC, Shifter), two DAGs, and a program sequencer for parallel operation.
• On-Chip Memory: 80K bytes total, comprising 16K words (24-bit) Program RAM and 16K words (16-bit) Data RAM.
• Serial Ports: Two double-buffered synchronous serial ports (SPORT0/SPORT1) with hardware companding and automatic data buffering.
• DMA Interfaces: Includes a 16-bit Internal DMA port for high-speed access and an 8-bit Byte DMA port for transparent transfers to external byte-wide memory.

Digital Signal Processor Dsp Applications

• Digital Signal Processing in battery-operated portable equipment due to low power modes.
• High-speed numeric processing applications requiring single-cycle instruction execution.
• Systems utilizing zero-overhead looping and conditional instruction execution for efficient code density.

Digital Signal Processor Dsp Procurement Notes

Verify package availability; the datasheet specifies 128-lead LQFP and 144-Ball Mini-BGA options. Confirm that the 'KSTZ' suffix corresponds to the specific temperature range and lead-free compliance required for the target application. Ensure development tools such as the ADSP-2100 Family Development Software or EZ-KIT Lite are compatible with the selected processor variant.

Digital Signal Processor Dsp Selection Notes

Select this component when code compatibility with the broader ADSP-2100 family is required alongside extended instruction sets like bit manipulation and x-squared multiplication. Consider the 19 ns instruction cycle and 52 MIPS performance for real-time processing needs. Evaluate the integrated memory size against external overlay requirements, as the device supports up to two 8K external memory segments via the PMOVLAY/DMOVLAY registers.

Digital Signal Processor Dsp Part Context

The ADSP-2183 belongs to the ADSP-2100 family of DSPs, which utilize a Harvard architecture with separate buses for program and data memory. This family is characterized by its ability to fetch instructions and operands simultaneously. The ADSP-2183 specifically adds integration features like dual serial ports and extensive DMA capabilities compared to base core models, making it suitable for complex system interfaces without external glue logic.

Digital Signal Processor Dsp Replacement Considerations

For direct pin-compatible replacements within the same package, consider other variants in the ADSP-218x series (e.g., ADSP-2189M) if higher clock speeds or additional features are needed. Verify that any substitute maintains the ADSP-2100 instruction set compatibility and memory map structure to ensure software portability.
