Product details
Overview
ADSP-21160NKBZ-100 from Analog Devices is a 100 MHz, 32-bit SIMD-capable SHARC® digital signal processor with dual 40-bit floating-point computational units (PEX/PEY), 4 Mbits of on-chip dual-ported SRAM, and integrated I/O processor supporting 14 zero-overhead DMA channels - deployed in professional audio mixing consoles, medical ultrasound beamformers, and radar signal processors.
For engineers reviewing the ADSP-21160NKBZ-100 datasheet, ADSP-21160NKBZ-100 pinout, ADSP-21160NKBZ-100 application, or ADSP-21160NKBZ-100 equivalent, key selection criteria include its 100 MHz instruction rate, 1.9 V core supply, 400-ball PBGA package, SIMD-enabled FFT and FIR performance, and glueless multiprocessing via six link ports.
Technical Context
The ADSP-21160NKBZ-100 implements a Super Harvard architecture with four independent buses enabling simultaneous dual data fetch, instruction fetch, and nonintrusive I/O - sustaining up to four 32-bit transfers per cycle between memory and core. Its dual processing elements (PEX and PEY) execute identical instructions on independent data streams under SIMD mode, enabled via the PEYEN bit in MODE1.
Memory subsystem includes two 2M-bit dual-ported SRAM blocks supporting concurrent single-cycle access by core, I/O processor, and DMA. The external 64-bit parallel bus operates at 100 MHz with programmable wait states, glueless interfacing to SBSRAM/DRAM, and unified 4G-word address space shared across multiprocessor systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Clock Rate | 100 MHz (10 ns instruction cycle) - enables real-time execution of 1024-point complex FFT in 92 μs. |
| Computational Architecture | Single-instruction, multiple-data (SIMD) with PEX and PEY units - doubles throughput for math-intensive algorithms like FIR/IIR filtering. |
| On-Chip Memory | 4 Mbits dual-ported SRAM (2 × 2M-bit blocks) - supports independent concurrent access by core, DMA, and host without contention. |
| I/O Bandwidth | 6 link ports @ 100 MB/s each + 2 serial ports @ 50 Mbps each - enables low-latency point-to-point interprocessor communication. |
| Power Supply | 1.9 V core / 3.3 V I/O - reduces dynamic power vs. ADSP-21160M while maintaining backward compatibility with 3.3 V peripherals. |
| DMA Channels | 14 zero-overhead DMA channels - offloads data movement for serial, link, external port, and host interface transfers without CPU intervention. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLKIN | External clock input | Accepts 25–50 MHz crystal or oscillator; feeds on-chip PLL to generate 100 MHz core clock (4× ratio). |
| RESET | Asynchronous reset input | Active-low signal that initializes all internal registers, disables PEX/PEY, and forces boot sequence reinitialization. |
| BMS, EBOOT, LBOOT | Boot configuration inputs | Determine boot source: 8-bit EPROM, host processor, or link port - critical for system startup reliability. |
| DATA63–0 | 64-bit bidirectional data bus | Glueless interface to external memory/peripherals; supports 16/32/48/64-bit packed transfers with byte enable control. |

| LXDAT7–0 (LX0–LX5) | Six 8-bit link port data buses | Enable full-duplex, point-to-point inter-DSP communication at 100 MB/s per port - no external arbitration logic required. |
| DR0/DT0, DR1/DT1 | Two synchronous serial port I/O | Support TDM, μ-law/A-law companding, and programmable word length (3–32 bits) for audio codec interfacing. |
| JTAG TCK/TMS/TDO/TDI | IEEE 1149.1 test access port | Enables boundary-scan testing, in-circuit emulation, and real-time debugging without halting core execution. |
Key Features
| Feature | Design Value |
|---|---|
| Dual DAG hardware circular buffers | Two independent data address generators support up to 32 circular buffers - eliminates software overhead in FIR filter delay lines and FFT bit-reversal addressing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital signal processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-21161NKBCZ-100 | Same 100 MHz SHARC core but with 256-pin CSP package (13 mm × 13 mm); lacks link ports and external 64-bit bus. | Targeted at space-constrained embedded audio codecs and portable medical devices where inter-DSP communication is unnecessary. | Select when board area is critical and multiprocessing is not required - trades link/external bus flexibility for compact footprint. |
| TMS320C6748ZWT | 300 MHz C67x DSP core (VLIW), 128 KB L2 RAM, no on-chip dual-ported SRAM; requires external memory for large buffers. | Used in cost-sensitive industrial gateways and communications infrastructure where fixed-point performance dominates over floating-point precision. | Select for higher raw MIPS in fixed-point tasks but accept added design complexity from external memory interface and lack of native SIMD floating-point acceleration. |
Compared with ADSP-21161NKBCZ-100, the ADSP-21160NKBZ-100 provides full glueless multiprocessing scalability and larger on-chip memory bandwidth; versus TMS320C6748ZWT, it delivers superior IEEE 754 floating-point determinism and lower latency for real-time control loops - making it preferred for safety-critical audio, imaging, and radar systems.

FAQ
What is the core voltage requirement for ADSP-21160NKBZ-100?
The ADSP-21160NKBZ-100 requires a dedicated 1.9 V ± 3% supply for its digital core (VDDINT), separate from the 3.3 V I/O supply (VDDEXT). This lower core voltage enables higher clock efficiency and reduced power dissipation compared to the ADSP-21160M variant, while maintaining full functional compatibility with 3.3 V peripheral interfaces.
Does ADSP-21160NKBZ-100 support IEEE 754 single-precision floating-point arithmetic?
Yes, the ADSP-21160NKBZ-100 fully supports IEEE 754 32-bit single-precision floating-point operations in both PEX and PEY computational units. It also supports 40-bit extended-precision floating-point and 32-bit fixed-point formats, with hardware acceleration for multiply-accumulate, FFT butterfly, and transcendental functions - all accessible via its 48-bit instruction word.
How many link ports does ADSP-21160NKBZ-100 have, and what is their maximum throughput?
The ADSP-21160NKBZ-100 integrates six independent 8-bit link ports (LX0–LX5), each capable of 100 MB/s bidirectional transfer at the 100 MHz core clock rate. These ports support glueless point-to-point interprocessor communication and can be configured in 2D or 3D topologies - enabling scalable multiprocessor arrays without external switching logic.
Is ADSP-21160NKBZ-100 pin-compatible with earlier ADSP-21160M variants?
No, ADSP-21160NKBZ-100 is not pin-compatible with ADSP-21160M variants due to differences in power supply requirements (1.9 V core vs. 2.5 V) and updated thermal pad layout. While functionally and code-compatible at the assembly level, PCB redesign is required to accommodate the distinct VDDINT routing, decoupling, and thermal management specifications of the ADSP-21160NKBZ-100.
What boot sources are supported by ADSP-21160NKBZ-100?
The ADSP-21160NKBZ-100 supports three boot modes controlled by BMS, EBOOT, and LBOOT pins: 8-bit EPROM (via external address/data bus), host processor (16- or 32-bit parallel interface), or link port (serial download from another SHARC device). Boot configuration is latched at power-up reset and determines initial program load path into on-chip SRAM.
