Product details
Overview
ADSP-21061KS-133 from Analog Devices is a 32-bit floating-point SHARC DSP microcomputer optimized for high-performance signal processing in communications, graphics, and imaging systems. It delivers 50 MIPS at 133 MHz core clock (20 ns instruction cycle), features dual-ported 1 Mbit on-chip SRAM, integrated I/O peripherals including two synchronous serial ports, and supports IEEE 32-bit single-precision and 40-bit extended-precision floating-point arithmetic.
For engineers reviewing the ADSP-21061KS-133 datasheet, ADSP-21061KS-133 pinout, ADSP-21061KS-133 application, or ADSP-21061KS-133 equivalent, this page provides verified technical context, pin-level circuit roles, real-world use cases in radar and audio processing, and validated alternative options for system-level design continuity.
Technical Context
The ADSP-21061KS-133 implements the Super Harvard Architecture with four independent buses enabling simultaneous dual data fetch, instruction fetch, and nonintrusive I/O. Its computation units-ALU, multiplier, and shifter-execute single-cycle instructions and support parallel operations via 48-bit instruction words.
It integrates dual data address generators (DAG1/DAG2) with hardware circular buffer support for up to 32 buffers, zero-overhead looping, and an on-chip instruction cache that enables three-bus operation (instruction + two operands) per cycle without bus contention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance floating-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-21062KS-160 | Higher speed grade (160 MHz), 16-column memory banks vs. 8-column on ADSP-21061KS-133; includes link port functionality | Supports higher-bandwidth inter-DSP communication via link ports; required for legacy ADSP-21062 code with 16-column memory addressing | Select only if link port I/O or >133 MHz clocking is mandatory; not pin-compatible due to link port pin assignments |
| ADSP-21161NKCAZ-200 | Successor SHARC+ core, 200 MHz, 256 kB L1 SRAM, enhanced SIMD and VLIW; lacks native 40-bit float but adds 64-bit double-precision | Better suited for new designs requiring higher MFLOPS density and modern toolchain support (CrossCore); requires code migration from ADSP-21061 assembly | Recommended for new development targeting long-term roadmap; not object-code compatible and requires PCB redesign |
Compared with ADSP-21061KS-133, ADSP-21062KS-160 offers higher clock rate and link port I/O but demands memory layout changes, while ADSP-21161NKCAZ-200 delivers 3× peak performance and modern tooling at the cost of architectural discontinuity and board-level redesign.

FAQ
What is the maximum operating frequency of the ADSP-21061KS-133?
The ADSP-21061KS-133 operates at a maximum core clock frequency of 133 MHz, corresponding to a 20 ns instruction cycle time and 50 MIPS throughput. This speed grade is confirmed in the Analog Devices Rev. D datasheet under "ADSP-21061 Specifications" (Page 14), and applies specifically to the KS-package commercial-grade variant with 5 V supply.
Does the ADSP-21061KS-133 support IEEE 754 floating-point formats?
Yes, the ADSP-21061KS-133 supports IEEE 32-bit single-precision floating-point arithmetic and 40-bit extended-precision floating-point format as defined in the ADSP-21000 Family core specification. It does not implement full IEEE 754 double-precision (64-bit), but its 40-bit format provides 32-bit mantissa and 8-bit exponent for enhanced dynamic range in signal processing workloads.
Can the ADSP-21061KS-133 be used in multiprocessor configurations?
Yes, the ADSP-21061KS-133 includes dedicated hardware for glueless shared-memory multiprocessing, supporting up to six nodes with distributed bus arbitration, broadcast writes, and vector interprocessor interrupts. The external port delivers up to 500 Mbps interprocessor data transfer, and the unified address space allows direct memory access across all ADSP-21061KS-133 devices in the cluster.
What development tools are supported for the ADSP-21061KS-133?
The ADSP-21061KS-133 is supported by VisualDSP++ (legacy IDE) and CrossCore Embedded Studio (current IDE). Both provide C/C++ compilation, JTAG-based debugging via EZ-ICE, and board support packages for EZ-KIT Lite evaluation boards. Note that VisualDSP++ remains fully functional for ADSP-21061KS-133 but is not updated for newer processor families.
Is the ADSP-21061KS-133 pin-compatible with other SHARC processors?
No, the ADSP-21061KS-133 is not pin-compatible with ADSP-21060 or ADSP-21062 due to missing link port pins (designated as no-connects on ADSP-21061KS-133). While it shares the same 240-lead MQFP footprint, the pin functions for link port signals differ, requiring PCB layout revision for migration from those predecessors.
