Product details
Overview
ADSP-21062KSZ-160 from Analog Devices is a 40 MHz, 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, integrated DMA controller, six link ports, and IEEE JTAG 1149.1 debug interface - deployed in real-time audio processing, radar beamforming, and medical imaging systems.
For engineers reviewing the ADSP-21062KSZ-160 datasheet, ADSP-21062KSZ-160 pinout, ADSP-21062KSZ-160 application, or ADSP-21062KSZ-160 equivalent, key selection criteria include sustained 80 MFLOPS performance, 240-ball PBGA package compatibility, host processor interface timing, and multiprocessor bus arbitration support for scalable DSP arrays.
Technical Context
The ADSP-21062KSZ-160 implements a Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data operand access, and nonintrusive I/O - all within a single 25 ns cycle. Its dual data address generators (DAG1/DAG2) support hardware circular buffers and bit-reverse addressing essential for FFT and filter execution.
It integrates a dedicated I/O processor (IOP), 10-channel DMA controller with background transfer capability, and a programmable external port supporting 4-gigaword addressing, page-mode DRAM, and configurable wait states - enabling direct interfacing to legacy peripherals without glue logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar floating-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-21060KSZ-160 | 4 Mbit on-chip SRAM, same 40 MHz clock, identical PBGA package - but lacks link port DMA channel sharing with serial ports. | Better suited for memory-intensive standalone DSP tasks; less optimal for tightly coupled multiprocessor arrays requiring serial+link coordination. | Select when larger on-chip memory is prioritized over link port flexibility in distributed architectures. |
| ADSP-21062LKSZ-160 | 3.3 V core voltage (vs. 5 V), lower power dissipation, same 2 Mbit SRAM and 40 MHz speed - pin-compatible PBGA footprint. | Preferred for battery-powered or thermally constrained systems where power efficiency outweighs legacy 5 V peripheral compatibility. | Choose for new designs targeting reduced thermal load and improved power efficiency without sacrificing performance or package layout. |
Compared with ADSP-21062KSZ-160, ADSP-21060KSZ-160 offers double on-chip memory at the cost of reduced link port versatility, while ADSP-21062LKSZ-160 delivers identical compute capability at 3.3 V for lower power - making the original ideal for 5 V industrial systems needing balanced memory, I/O, and multiprocessing features.

FAQ
What is the maximum sustained floating-point performance of the ADSP-21062KSZ-160?
The ADSP-21062KSZ-160 delivers 80 MFLOPS sustained performance under real-world workloads, verified by benchmarked 1024-point complex FFT execution in 0.46 µs. This reflects its ability to maintain parallel multiply-accumulate operations with dual memory accesses and instruction fetches across all functional units without pipeline stalls.
Does the ADSP-21062KSZ-160 support direct connection to a 32-bit host microprocessor?
Yes, the ADSP-21062KSZ-160 includes a fully asynchronous host processor interface compatible with both 16-bit and 32-bit microprocessors. It uses memory-mapped addressing via the external port, with HBR/HBG/REDY handshaking, enabling direct read/write access to internal SRAM and IOP registers without additional glue logic.
How many link ports does the ADSP-21062KSZ-160 have, and what is their aggregate bandwidth?
The ADSP-21062KSZ-160 integrates six independent 4-bit link ports, each capable of 8 bits per core cycle at 40 MHz, yielding an aggregate bandwidth of 240 MBps. This is confirmed in Table 2 and Figure 1 of the Rev. H datasheet, and supports deterministic point-to-point communication in multiprocessor DSP arrays.
Is the ADSP-21062KSZ-160 pin-compatible with other members of the ADSP-2106x family?
The ADSP-21062KSZ-160 shares the same 225-ball PBGA package and pinout with ADSP-21062LKSZ-160 and ADSP-21060KSZ-160 variants. However, voltage differences (5 V vs. 3.3 V) and SRAM size (2 Mbit vs. 4 Mbit) require careful review of power supply and memory mapping - mechanical compatibility does not imply electrical or functional drop-in replacement.
What development tools are officially supported for the ADSP-21062KSZ-160?
Analog Devices officially supports ADSP-21062KSZ-160 with VisualDSP++ IDE (legacy) and CrossCore Embedded Studio (current). Both provide C/C++ compilation, JTAG-based debugging, and board support packages for EZ-KIT Lite evaluation boards - with VisualDSP++ remaining the only IDE validated for VDK RTOS integration on this SHARC generation.
