Product details
Overview
ADSP-2184NKSTZ-320 from Analog Devices is a 16-bit fixed-point DSP microcomputer optimized for real-time signal processing in embedded audio, telecom, and industrial control systems. It delivers 80 MIPS sustained performance at 12.5 ns instruction cycle time (1.8 V core), features 4K words of on-chip program RAM and 4K words of data RAM, dual serial ports with hardware companding, and supports full-memory or host-mode booting via byte DMA or internal DMA interfaces.
For engineers reviewing the ADSP-2184NKSTZ-320 datasheet, ADSP-2184NKSTZ-320 pinout, ADSP-2184NKSTZ-320 application, or ADSP-2184NKSTZ-320 equivalent, key selection criteria include its 100-lead LQFP package, 1.8 V core voltage compatibility, zero-overhead looping capability, 200-cycle power-down recovery, and ICE-Port™ debug interface support in final-system environments.
Technical Context
The ADSP-2184NKSTZ-320 implements the ADSP-2100 base architecture with three independent computational units - ALU, 40-bit MAC, and barrel shifter - enabling parallel operand fetches and multifunction instructions per cycle. Its dual DAGs support circular buffering and modulo addressing, while the program sequencer provides conditional branching and subroutine calls with single-cycle latency.
It integrates two double-buffered synchronous serial ports (SPORT0/SPORT1) supporting μ-law/A-law companding per CCITT G.711, programmable 16-bit interval timer with prescaler, 13 flag I/O pins (8 configurable), and flexible memory interface with programmable wait states, byte DMA (up to 4 MB), and 16-bit internal DMA port for transparent on-chip RAM access.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-2185NKSTZ-320 | 16K words program RAM / 16K words data RAM; otherwise identical architecture and pinout | Supports larger algorithm footprints (e.g., multi-band audio codecs, complex filter banks) | Select when on-chip memory requirements exceed 4K/4K but same LQFP footprint and toolchain compatibility are required |
| TMS320VC5402PGE | 16-bit C54x architecture; 100-MIPS @ 10-ns cycle; different instruction set and memory map | Lacks hardware companding; requires software-based μ/A-law; uses different development tools (CCS vs. VisualDSP++) | Choose for migration paths requiring TI ecosystem integration or higher raw MIPS, accepting firmware rework and toolchain change |

FAQ
What is the core supply voltage requirement for ADSP-2184NKSTZ-320?
The ADSP-2184NKSTZ-320 requires a 1.8 V ±0.1 V core supply (VDDINT) for nominal operation at 80 MIPS. Its I/O banks operate at 3.3 V (VDDIO), and all input pins tolerate up to 3.6 V regardless of VDDIO setting - enabling safe interfacing with mixed-voltage systems without level shifters.
Does ADSP-2184NKSTZ-320 support automatic boot from external memory?
Yes, ADSP-2184NKSTZ-320 supports automatic boot from byte-wide external memory (e.g., EPROM) using its Byte DMA port. When configured in Mode C = 0, Mode A = 0, it loads the first 32 program memory words from byte memory space before starting execution - a feature confirmed in the ADSP-218xN Rev. A datasheet Section "Modes Of Operation".
How many external interrupts does ADSP-2184NKSTZ-320 support?
ADSP-2184NKSTZ-320 supports up to six external interrupts: four dedicated pins (IRQ2, IRQL0, IRQL1, IRQE) plus two additional interrupt-capable signals (IRQ0, IRQ1) routed through SPORT1 configuration. IRQ2, IRQ0, and IRQ1 are programmable as edge- or level-sensitive, while IRQL0/IRQL1 are level-sensitive and IRQE is edge-sensitive.
Is ADSP-2184NKSTZ-320 pin-compatible with other ADSP-218xN family members?
Yes, ADSP-2184NKSTZ-320 is fully pin-compatible with all ADSP-218xN series variants (e.g., ADSP-2185N, ADSP-2189N) in the same package type. The ADSP-218xN datasheet explicitly states: "All series members are pin-compatible and are differentiated solely by the amount of on-chip SRAM." This applies to both 100-lead LQFP and 144-ball BGA packages.
What debug interface does ADSP-2184NKSTZ-320 provide?
ADSP-2184NKSTZ-320 includes the ICE-Port™ emulator interface, a proprietary Analog Devices debug port supporting non-intrusive real-time debugging, breakpoint insertion, register and memory inspection, and flash programming - even in final-system deployments without halting application execution.
