Product details
Overview
ADSP-21061KSZ-133 from Analog Devices is a 50 MHz, 50 MIPS SHARC® floating-point DSP microcomputer with dual-ported 1 Mbit on-chip SRAM, two synchronous serial ports, host interface, six-channel DMA, and JTAG emulation support-designed for real-time communications, imaging, and graphics signal processing systems.
For engineers reviewing the ADSP-21061KSZ-133 datasheet, ADSP-21061KSZ-133 pinout, ADSP-21061KSZ-133 application, or ADSP-21061KSZ-133 equivalent, key selection criteria include IEEE 32-bit/40-bit floating-point execution, 20 ns instruction cycle time, 240-lead MQFP thermal package, dual-DAG hardware circular buffering, and multiprocessor bus arbitration capability.
Technical Context
The ADSP-21061KSZ-133 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data fetch, and nonintrusive I/O-achieving single-cycle execution of all instructions including multiply-accumulate and FFT butterfly operations. Its dual data address generators (DAG1/DAG2) support up to 32 hardware circular buffers with automatic wraparound for delay-line and filter coefficient management.
On-chip resources include an instruction cache that enables three-bus operation (instruction + two operands), 1 Mbit dual-ported SRAM split into two 0.5 Mbit blocks for concurrent core and I/O/DMA access, and a dedicated I/O processor with memory-mapped registers for serial port, timer, and host interface control.
Key Specifications

|---|---|
| Clock Frequency | 133 MHz maximum operating frequency - supports 7.5 ns instruction cycle time and sustained 80 MFLOPS performance. |
| Floating-Point Format | IEEE 32-bit single-precision and 40-bit extended-precision - enables high-dynamic-range computation for audio and radar algorithms. |
| On-Chip Memory | 1 Mbit dual-ported SRAM (two 0.5 Mbit blocks) - allows concurrent core + DMA or I/O processor access without bus contention. |
| Serial Ports | Two synchronous serial ports - each supports up to 50 Mbps TDM multichannel mode with μ-law/A-law companding and keyword detection. |
| DMA Channels | Six independent DMA channels - four via serial ports, two via external port - enables zero-overhead transfers between memory, peripherals, and host processor. |
| Multiprocessing Support | Glueless 6-node shared-memory architecture with distributed bus arbitration and broadcast write - eliminates external logic for scalable DSP arrays. |

| HBR/HBG/REDY | Host Bus Interface Control | Asynchronous handshake signals - allow 16-/32-bit host processors to directly access ADSP-21061KSZ-133 internal memory and DMA registers at full core speed. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-overhead looping | Single-cycle loop setup enables tight FIR/IIR filter kernels without branch penalty - critical for deterministic latency in audio and telecom systems. |
| Dual DAG hardware circular buffering | Two independent DAGs with modulo addressing support up to 32 concurrent circular buffers - eliminates software pointer management overhead in FFT and convolution. |
| Instruction cache | Selective caching of conflict-prone instructions only - maintains full 50 MIPS throughput during nested loops while minimizing die area and power. |
| 16-bit floating-point storage format | On-the-fly conversion between 32-bit and 16-bit FP formats in one instruction - doubles effective on-chip data capacity for coefficient tables without precision loss in pre-processing stages. |
| Bus lock for semaphores | Hardware-enforced indivisible read-modify-write sequences - ensures atomic interprocessor synchronization in shared-memory multiprocessing without software mutexes. |

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 210 MHz clock rating (10 ns cycle), 120 MFLOPS peak, 3.3 V core supply - requires redesigned power delivery and signal integrity layout. | Targeted at next-generation radar and wideband comms where >100 MFLOPS sustained throughput is mandatory. | Select when algorithm complexity exceeds ADSP-21061KSZ-133's 80 MFLOPS sustained limit - verify thermal margin in MQFP package at 210 MHz. |
| ADSP-21161NKCPZ-200 | SHARC+ architecture, 200 MHz, dual-core, 256 KB L1 SRAM per core, 2x faster instruction cache - not pin-compatible; requires PCB redesign. | Designed for multicore parallel workloads (e.g., multi-stream video analytics) where task partitioning across cores improves throughput. | Choose for new designs needing scalability beyond single-core SHARC - avoid for drop-in replacement due to incompatible pinout and memory map. |
Compared with ADSP-21061KSZ-133, ADSP-21065LKSZ-210 delivers higher throughput but demands tighter power and timing margins, while ADSP-21161NKCPZ-200 offers true multicore parallelism at the cost of complete hardware redesign - neither is pin-compatible, making ADSP-21061KSZ-133 optimal for legacy SHARC-based systems requiring proven reliability and thermal stability.

FAQ
What is the maximum operating frequency of the ADSP-21061KSZ-133?
The ADSP-21061KSZ-133 is rated for a maximum clock frequency of 133 MHz, delivering a 7.5 ns instruction cycle time and sustained 80 MFLOPS performance. This speed grade is validated across the industrial temperature range (–40°C to +85°C) and requires a clean, low-jitter 133 MHz clock source applied to the CLKIN pin. The part achieves this performance using an internal PLL and is specified in Analog Devices' Rev. D datasheet under "ADSP-21061 Specifications" section.
Does the ADSP-21061KSZ-133 support IEEE 754 floating-point arithmetic?
Yes, the ADSP-21061KSZ-133 fully supports IEEE 754-compliant 32-bit single-precision and 40-bit extended-precision floating-point data formats. It also supports 32-bit fixed-point arithmetic. The 40-bit extended format uses a 32-bit mantissa and 8-bit exponent, providing >120 dB dynamic range - essential for maintaining numerical accuracy in deep-pipeline radar and medical imaging algorithms executed on the ADSP-21061KSZ-133.
Is the ADSP-21061KSZ-133 pin-compatible with other SHARC processors?
The ADSP-21061KSZ-133 is pin-compatible with the ADSP-21060 and ADSP-21062 in the 240-lead MQFP package, as confirmed in the "Porting Code From the ADSP-21060 or ADSP-21062" section of the Rev. D datasheet. However, link port pins on those devices are no-connects on the ADSP-21061KSZ-133, and memory column depth differs (8 vs. 16 columns per bank), requiring minor memory map adjustments during migration.
What development tools are supported for the ADSP-21061KSZ-133?
Analog Devices officially supports the ADSP-21061KSZ-133 with VisualDSP++® - its legacy IDE for SHARC processors - including C/C++ compiler, assembler, linker, and EZ-KIT Lite evaluation board drivers. CrossCore Embedded Studio does not support ADSP-21061KSZ-133, as it targets newer processor families. Emulation is enabled via the IEEE 1149.1 JTAG port using ICE-100B or similar Analog Devices emulators.
How is memory organized in the ADSP-21061KSZ-133?
The ADSP-21061KSZ-133 contains 1 Mbit of dual-ported on-chip SRAM divided into two 0.5 Mbit blocks (Block 0 and Block 1), each with eight 16-bit columns and 4k words per column. Memory can be configured as 32k × 32-bit, 64k × 16-bit, or 16k × 48-bit - all within the unified 4-gigaword address space. Block 0 starts at 0x00020000; Block 1 begins contiguously thereafter, with aliasing support for backward compatibility with ADSP-21062 code.
