Product Overview
The ADSP-21266SKSTZ-1B is a high-performance 32/40-bit floating-point SHARC® DSP by Analog Devices. Running at 150 MHz, it delivers up to 900 MFLOPS of peak performance via dual SIMD cores, making it ideal for consumer audio, professional signal processing, and medical instrumentation. Its 2Mbit on-chip dual-port SRAM ensures low-latency execution of complex algorithms like FFTs and filters, while integrated hardware accelerators, audio interfaces, and clock routing circuits simplify system design. Housed in a lead-free 144-LQFP package with exposed thermal pad, it is well-suited for multi-channel automotive audio, studio processors, and precision automation systems.
Core Advantages
SIMD Core Parallel Processing Architecture
Utilizes dual computational blocks that can run parallel math instructions concurrently, effectively doubling the single-core data throughput and significantly shortening execution cycles for massive math processing arrays.
Substantial 2Mbit Dual-Port SRAM Core Memory
Integrates 2 Megabits of high-speed on-chip SRAM, divided into independent blocks. This allows simultaneous access from both the internal processing registers and background DMA channels without experiencing structural system stalls.
Dedicated Hardware Audio Peripheral Complex
Features an elite combination of synchronous serial ports (SPORTs), digital audio interfaces (DAI), and programmable precision clock generators that dramatically simplify interconnect routines to external codecs and digital DAC converters.
Advanced Hardware Mathematical Accelerators
Equipped with internal fixed-function acceleration blocks specifically optimized for processing complex execution routines like IIR (Infinite Impulse Response) and FIR (Finite Impulse Response) filters directly at the silicon layer.

Frequently Asked Questions
Q1: Is your current stock inventory of the ADSP-21266SKSTZ-1B fully original and new?
A: Yes, we guarantee that all ADSP-21266SKSTZ-1B SHARC processors in our inventory are 100% brand-new, factory-original products from Analog Devices Inc., kept and handled under strict anti-static ESD shielding safeguards.
Q2: What do the unique character elements inside the “SKSTZ” string mean for this component type?
A: The “S” designation specifies the 150MHz clock performance rate. The “K” letter specifies the commercial operating temperature standard (0°C to +70°C). The “ST” characters outline the low-profile quad flatpack (LQFP) outline format, while the “Z” denotes a lead-free green package formulation.
Q3: How does the Digital Audio Interface (DAI) help in routing digital signals across an audio design?
A: The DAI includes a fully flexible Signal Routing Unit (SRU). This hardware matrix allows engineers to route any internal peripheral to any physical external pin dynamically via software configurations, drastically reducing PCB layout complexity and eliminating jumper paths.
Q4: How can our hardware development team download device drivers, pin placement sheets, or check multi-reel bulk discount structures?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
