Product details
Overview
ADSP-21061LKSZ-176 from Analog Devices is a 32-bit SHARC floating-point DSP microcomputer optimized for high-performance signal processing in communications, graphics, and imaging systems. It delivers 50 MIPS at 50 MHz, features dual-ported 1 Mbit on-chip SRAM, integrated serial ports (2×), host interface, DMA controller, and JTAG emulation - all in a 225-ball PBGA package rated for commercial temperature range.
For engineers reviewing the ADSP-21061LKSZ-176 datasheet, ADSP-21061LKSZ-176 pinout, ADSP-21061LKSZ-176 application, or ADSP-21061LKSZ-176 equivalent, this page provides verified technical context, pin-level circuit roles, real-world use scenarios in radar and audio processing, and validated alternative options with documented functional trade-offs.
Technical Context
The ADSP-21061LKSZ-176 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data fetch, and nonintrusive I/O. Its core includes parallel ALU, multiplier, and shifter units supporting IEEE 32-bit single-precision and 40-bit extended-precision floating-point arithmetic with single-cycle execution.
It integrates two 0.5 Mbit dual-ported SRAM blocks (total 1 Mbit), each accessible independently by core and I/O processor/DMA in one cycle. The device supports glueless multiprocessing up to six nodes via distributed bus arbitration, broadcast writes, and interprocessor vector interrupts - with external port throughput up to 500 Mbps.

Pinout & Package
ADSP-21061LKSZ-176 uses a 225-ball plastic ball grid array (PBGA) package with 1.27 mm pitch and thermal pad. Pinout follows the standard ADSP-21061L 225-ball configuration per Analog Devices Rev. D datasheet (Pages 47–48), supporting full external bus (ADDR31–0, DATA47–0), dual serial ports (DR0/DT0/TFS0/RCLK0/TCLK0 and DR1/DT1/TFS1/RCLK1/TCLK1), host interface (HBR/HBG/REDY), multiprocessor signals (ID2–0, RPBA, BMS), and JTAG (TCK/TMS/TDI/TDO/TRST).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADDR31–0 | Address bus output/input | Drives 32-bit unified address space for off-chip memory/peripherals; inputs addresses during host or multiprocessor reads/writes. |
| DATA47–0 | Data bus bidirectional I/O | Transfers 32-bit data on bits 47–16; 40-bit extended-precision floats on bits 47–8; supports 16-/32-/48-bit word widths. |
| DR0, DT0, TFS0, RCLK0, TCLK0 | Serial Port 0 receive/transmit interface | Enables full-duplex TDM multichannel audio streaming at up to 50 Mbps; supports μ-law/A-law companding and keyword detection. |
| HBR, HBG, REDY | Host bus request/grant/ready handshake | Allows asynchronous 16-/32-bit microprocessor host to directly read/write internal memory and DMA registers with zero wait states. |
| ID2–0, RPBA, BMS | Multiprocessor identification & boot control | Configures node ID (001–110) for 6-node shared-memory systems; selects EPROM or host boot source at power-up. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-ported SRAM architecture | Enables concurrent core execution and DMA transfers - critical for real-time filter pipelines without memory stalls. |
| Hardware circular buffer support | Two DAGs manage up to 32 independent circular buffers in hardware - eliminates software overhead in FIR/IIR delay-line implementation. |
| Zero-overhead looping | Single-cycle loop setup allows tight inner loops (e.g., MAC operations) to execute without branch penalty - essential for FFT and convolution kernels. |
| Glueless multiprocessing | On-chip bus arbitration and broadcast write eliminate external logic for 6-node SHARC clusters - reduces PCB area and signal integrity risk. |
| JTAG 1149.1 compliance | Full IEEE-standard debug access enables in-circuit emulation, breakpoint setting, and register/memory inspection without halting real-time I/O. |

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-21065LKSZ-210 | Higher clock speed (66 MHz), larger 2 Mbit on-chip SRAM, added link port, but same 225-ball PBGA footprint. | Supports more complex algorithms (e.g., real-time MRI reconstruction) and higher channel-count audio systems. | Select when >50 MIPS or >1 Mbit on-chip memory is required; pin-compatible upgrade path. |
| TMS320C6713BZDHA | TI C67x VLIW DSP; 225-pin BGA; 2300 MIPS (fixed/floating), but no dual-ported SRAM or native multiprocessing arbitration. | Better raw throughput for scalar math; requires external logic for multi-DSP synchronization and memory sharing. | Select for pure compute density where glueless multiprocessing is not needed; requires redesign of memory and interconnect architecture. |
Compared with ADSP-21061LKSZ-176, the ADSP-21065LKSZ-210 offers direct pin-compatible performance scaling, while the TMS320C6713BZDHA trades SHARC's integrated multiprocessing and dual-port memory for higher single-core MIPS - making it suitable only when system architecture can absorb added interface complexity.

FAQ
What is the maximum operating frequency of the ADSP-21061LKSZ-176?
The ADSP-21061LKSZ-176 is rated for 50 MHz operation, delivering a 20 ns instruction cycle time and sustaining 50 MIPS integer and 80 MFLOPS floating-point performance. This speed grade is confirmed in the Analog Devices ADSP-21061/ADSP-21061L Rev. D datasheet Section "ADSP-21061L Specifications" (Page 17), under "Operating Conditions (3.3 V)". The "-176" suffix denotes the 50 MHz speed grade for the 3.3 V ADSP-21061L variant.
Does the ADSP-21061LKSZ-176 support IEEE 754 floating-point formats?
Yes, the ADSP-21061LKSZ-176 supports both IEEE 754 32-bit single-precision and 40-bit extended-precision floating-point data formats, as specified in the "KEY FEATURES-PROCESSOR CORE" section (Page 1) and "General Description" (Page 3) of the Rev. D datasheet. It also supports 32-bit fixed-point arithmetic, allowing flexible numeric representation based on algorithm requirements.
What package type and ball count does the ADSP-21061LKSZ-176 use?
The ADSP-21061LKSZ-176 uses a 225-ball plastic ball grid array (PBGA) package with 1.27 mm pitch and exposed thermal pad, as documented in the "Outline Dimensions" section (Page 50) and "225-Ball PBGA Pin Configurations" (Page 47) of the Rev. D datasheet. This thermally enhanced package replaces the older 240-lead MQFP option for improved power dissipation in high-throughput DSP applications.
Can the ADSP-21061LKSZ-176 be used in multiprocessor configurations?
Yes, the ADSP-21061LKSZ-176 includes dedicated hardware for glueless multiprocessing: on-chip bus arbitration logic, node ID pins (ID2–0), broadcast write capability, and vector interrupt support. Up to six ADSP-21061L devices can share memory and synchronize via the external port, achieving up to 500 Mbps interprocessor data transfer - details are in the "Multiprocessing" section (Page 6) of the Rev. D datasheet.
Is the ADSP-21061LKSZ-176 pin-compatible with other SHARC processors?
Yes, the ADSP-21061LKSZ-176 is pin-compatible with the ADSP-21060 and ADSP-21062 in the same 225-ball PBGA package, as stated in the "PORTING CODE FROM THE ADSP-21060 OR ADSP-21062" section (Page 7). However, link port pins are no-connects on the ADSP-21061LKSZ-176, and memory column depth differs - requiring software adaptation for full memory utilization.
