Product details
Overview
ADSP-21061KS-160 from Analog Devices is a 5 V, 40 MHz SHARC floating-point DSP microcomputer with dual-ported 1 Mbit SRAM, integrated host interface, two synchronous serial ports, and six-channel DMA. It delivers 80 MFLOPS sustained performance and executes instructions in single cycles for real-time signal processing in communications infrastructure and imaging systems.
For engineers reviewing the ADSP-21061KS-160 datasheet, ADSP-21061KS-160 pinout, ADSP-21061KS-160 application, or ADSP-21061KS-160 equivalent, key selection considerations include its 240-lead MQFP package, IEEE 32-bit/40-bit floating-point support, dual-bus Harvard architecture enabling simultaneous instruction + dual-data fetch, and multiprocessor interface for glueless 6-node SHARC arrays.
Technical Context
The ADSP-21061KS-160 implements the Super Harvard Architecture with four independent buses (PM/DM address/data), enabling concurrent instruction fetch, dual data access, and nonintrusive I/O. Its core includes parallel ALU/multiplier/shifter units supporting IEEE 32-bit single-precision and 40-bit extended-precision floating-point arithmetic.
It integrates dual-ported on-chip SRAM (two 0.5 Mbit blocks), a dedicated I/O processor bus, JTAG-compliant test access port, and hardware circular buffer support via two DAGs. Memory configuration supports up to 32k words of 32-bit data or 16k words of 48-bit instructions within its unified 4-gigaword address space.

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-21061LKS-160 | 3.3 V core supply, lower power dissipation, same 40 MHz speed grade and pinout | Preferred for battery-powered or thermally constrained embedded systems requiring identical functionality at reduced voltage | Select when system-level power budget or thermal envelope prohibits 5 V operation |
| ADSP-21062KS-160 | Includes link port interface and 16-column memory banks vs. ADSP-21061's 8-column banks; otherwise functionally compatible | Suitable where inter-DSP high-speed point-to-point links are required, or legacy ADSP-21062 code must run without memory layout changes | Choose only if link port I/O or full 16-column memory addressing is mandatory |
Compared with ADSP-21061LKS-160, the ADSP-21061KS-160 offers higher noise immunity and legacy 5 V system compatibility; compared with ADSP-21062KS-160, it trades link port bandwidth for lower cost and simplified board routing in multiprocessor systems relying on broadcast-based communication.

FAQ
What is the operating voltage requirement for the ADSP-21061KS-160?
The ADSP-21061KS-160 requires a nominal 5 V supply for both core and I/O operation, as specified in the Rev. D datasheet Section "Operating Conditions (5 V)". It is not compatible with 3.3 V core logic and must be powered from a regulated 5 V source meeting ±5% tolerance and ripple limits per the Electrical Characteristics table.
Does the ADSP-21061KS-160 support IEEE 754 single-precision floating-point arithmetic?
Yes, the ADSP-21061KS-160 natively supports IEEE 32-bit single-precision floating-point computation in both its ALU and multiplier units, as confirmed in the "KEY FEATURES-PROCESSOR CORE" section. It also supports 40-bit extended-precision and 32-bit fixed-point formats, all executable in single cycles.
Can the ADSP-21061KS-160 be used in a multiprocessor configuration with other SHARC devices?
Yes, the ADSP-21061KS-160 includes on-chip distributed bus arbitration logic supporting glueless connection of up to six ADSP-21061 devices plus a host processor. Its multiprocessor interface provides broadcast writes, vector interrupts, and 500 Mbps interprocessor throughput over the external port.
What package type and pin count does the ADSP-21061KS-160 use?
The ADSP-21061KS-160 uses a 240-lead thermally enhanced MQFP (Metric Quad Flat Package) with 0.5 mm lead pitch and exposed thermal pad, as documented in the "Outline Dimensions" section (Page 50) and "240-Lead MQFP Pin Configurations" (Page 49) of the Rev. D datasheet.
Is the ADSP-21061KS-160 pin-compatible with the ADSP-21060 or ADSP-21062?
Yes, the ADSP-21061KS-160 is pin-compatible with the ADSP-21060 and ADSP-21062 processors per the "PORTING CODE FROM THE ADSP-21060 OR ADSP-21062" section. However, link port pins on those devices are no-connects on the ADSP-21061KS-160, and memory bank column depth differs (8 vs. 16 columns).
