Product details
Overview
ADSP-21160NCBZ-100 from Analog Devices is a 32-bit SHARC® digital signal processor with dual 100 MHz computational units (PEX/PEY), 4 Mbits of on-chip dual-ported SRAM, and SIMD architecture enabling 600 million math operations per second. It operates at 1.9 V core / 3.3 V I/O, features six 100 MB/s link ports, and targets high-throughput audio, medical imaging, and radar signal processing systems.
For engineers reviewing the ADSP-21160NCBZ-100 datasheet, ADSP-21160NCBZ-100 pinout, ADSP-21160NCBZ-100 application, or ADSP-21160NCBZ-100 equivalent, key selection criteria include its 100 MHz instruction rate, IEEE 32-/40-bit floating-point support, glueless multiprocessing capability, and 400-ball PBGA package compatibility with legacy SHARC toolchains.
Technical Context
The ADSP-21160NCBZ-100 implements a Super Harvard architecture with four independent buses-PM/DM address/data-enabling simultaneous instruction fetch, dual data read/write, and zero-overhead I/O. Its dual computational elements (PEX and PEY) execute identical instructions on independent data streams in SIMD mode, doubling throughput for FFT, FIR, and matrix operations versus SISD mode.
It integrates an I/O processor with 14 zero-overhead DMA channels, supports 4G-word external addressing, and provides glueless multiprocessing via distributed bus arbitration across up to six processors. The 400-ball PBGA package enables direct connection to ZBT SRAM, T1/E1 serial interfaces, and host microprocessors without external logic.

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-21161NKCAZ-100 | Same 100 MHz core, but uses 256-pin CSP instead of 400-ball PBGA; lacks link ports and has reduced SRAM (2 Mbits). | Targeted at space-constrained embedded audio, not multiprocessing or high-bandwidth I/O systems. | Choose when board area is critical and link/multiprocessing features are unnecessary. |
| ADSP-21469WBCZ-4A | Newer SHARC+ core at 450 MHz, 2 Mbytes L1 SRAM, integrated DDR2 controller, but requires updated toolchain and layout revision. | Designed for next-gen radar and AI-accelerated edge inference where legacy code porting is feasible. | Choose for higher throughput and modern peripherals; avoid if maintaining legacy SHARC-21160 codebase is mandatory. |
Compared with ADSP-21160NCBZ-100, ADSP-21161NKCAZ-100 trades package size and I/O bandwidth for compactness, while ADSP-21469WBCZ-4A offers significantly higher clock rate and memory bandwidth at the cost of architectural discontinuity and toolchain migration effort.

FAQ
What is the core architecture of the ADSP-21160NCBZ-100?
The ADSP-21160NCBZ-100 implements a Super Harvard architecture with dual 32-bit computational units (PEX and PEY), two independent data address generators (DAGs), and four dedicated buses (PM/DM address/data). It executes single-instruction, multiple-data (SIMD) operations at 100 MHz, delivering 600 million math operations per second. Its design emphasizes deterministic real-time performance for signal processing workloads, with no reliance on speculative execution or out-of-order pipelines.
Does the ADSP-21160NCBZ-100 support backward compatibility with earlier SHARC processors?
Yes, the ADSP-21160NCBZ-100 is assembly-source compatible with ADSP-2106x SHARC processors in SISD mode. Code written for ADSP-2106x can run unchanged on ADSP-21160NCBZ-100 when PEY is disabled. To leverage SIMD acceleration, minor modifications are required to exploit dual computational units-Analog Devices provides migration guides and compiler directives to assist this transition.
What memory interfaces does the ADSP-21160NCBZ-100 provide?
The ADSP-21160NCBZ-100 integrates 4 Mbits of on-chip dual-ported SRAM organized as two 2 Mbit blocks, supporting simultaneous access by core, DMA, and host. Its 64-bit external bus interfaces gluelessly to ZBT SRAM, SDRAM, and DRAM with programmable wait states and page-mode support. The unified 4G-word address space allows direct mapping of external peripherals and memory into the same logical space as internal resources.
How does multiprocessing work on the ADSP-21160NCBZ-100?
The ADSP-21160NCBZ-100 supports glueless multiprocessing via six 8-bit link ports (100 MB/s each) and a shared external bus with distributed arbitration logic. Up to six ADSP-21160NCBZ-100 processors can be interconnected without external glue logic, with broadcast writes and vector interrupts enabling coordinated task distribution. Interprocessor memory access occurs directly through the unified address space, achieving up to 400 MB/s throughput over the external port.
What development tools are supported for the ADSP-21160NCBZ-100?
Analog Devices officially supports ADSP-21160NCBZ-100 with VisualDSP++ IDE (legacy) and CrossCore Embedded Studio (current). Both provide C/C++ compilation, cycle-accurate simulation, JTAG-based debugging, and SHARC-specific libraries for FFT, filtering, and math functions. Hardware tools include ICE-100B emulators and EZ-KIT Lite evaluation boards with on-board SDRAM, audio codecs, and expansion headers for rapid prototyping.
