ADSP-2184NKCA-320

Digital Signal Processor Dsp Overview

The ADSP-2184NKCA-320 is a digital signal processor from the ADSP-218xN series, fabricated in a 0.18 μm CMOS process. It features a 12.5 ns instruction cycle time at 1.8 V, delivering 80 MIPS sustained performance with single-cycle execution. The device integrates up to 48K words of program RAM and 56K words of data RAM within a 144-ball BGA package. Key architectural components include an ALU, multiplier/accumulator, barrel shifter, two data address generators, and a program sequencer. System interfaces comprise two serial ports, a 16-bit internal DMA port, and a byte DMA port for external memory access.

Digital Signal Processor Dsp Feature Summary

• Single-cycle instruction execution with dual operand fetch capability via three-bus architecture
• Integrated on-chip memory: up to 48K words program RAM and 56K words data RAM
• Flexible I/O supporting 1.8 V, 2.5 V, or 3.3 V operation with 3.6 V input tolerance
• Low-power modes including power-down with 200 CLKIN cycle recovery and idle/slow idle states

Digital Signal Processor Dsp Applications

• Digital signal processing applications requiring high-performance fixed-point computation
• Battery-operated portable equipment utilizing low-power standby modes
• Systems requiring glueless interface to off-chip RAM and I/O peripherals
• Audio and telecommunications processing using SPORT companding hardware

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'C' against the manufacturer's ordering guide to confirm temperature range and packaging details. Ensure compatibility with existing ADSP-2100 family codebases due to architectural similarity. Confirm voltage requirements align with the 1.8 V internal operation specification. Check for availability of development tools supporting the ICE-Port emulator interface.

Digital Signal Processor Dsp Selection Notes

Select this model when 48K words of program memory and 56K words of data memory are sufficient for the application. Consider the 144-ball BGA package for space-constrained designs requiring high pin counts. Evaluate the need for the specific 320 MHz clock speed if lower frequencies suffice for power savings. Compare against other ADSP-218xN members based on required memory capacity and package type.

Digital Signal Processor Dsp Part Context

This component belongs to the ADSP-218xN series, which shares pin compatibility and base architecture across family members. Differentiation within the series is primarily determined by the amount of on-chip SRAM. The ADSP-2184N variant specifically offers 4K words of program memory and 4K words of data memory, while the N-series denotes enhanced features compared to earlier generations.

Digital Signal Processor Dsp Replacement Considerations

Direct substitutes within the ADSP-218xN series include ADSP-2185N, ADSP-2186N, ADSP-2187N, ADSP-2188N, and ADSP-2189N, differing mainly in memory size. Cross-family replacements like the ADSP-2181 require evaluation of memory and interface differences.
