Product details
Overview
ADSP-21060LKS-133 from Analog Devices is a 32-bit floating-point SHARC® digital signal processor with 4 Mbit dual-ported on-chip SRAM, 40 MIPS instruction rate at 33 MHz, and 3.3 V core supply. It implements Super Harvard Architecture with independent PM/DM buses, integrated DMA controller (10 channels), six link ports, two serial ports, and JTAG emulation support. Used in real-time audio processing, radar signal conditioning, and medical imaging systems requiring deterministic low-latency computation.
For engineers reviewing the ADSP-21060LKS-133 datasheet, ADSP-21060LKS-133 pinout, ADSP-21060LKS-133 application, or ADSP-21060LKS-133 equivalent, key selection criteria include on-chip memory size (4 Mbit), 3.3 V operation, MQFP_PQ4 package compatibility, IEEE 754 32-bit/40-bit floating-point support, and glueless multiprocessing capability via link and external ports.
Technical Context
The ADSP-21060LKS-133 executes single-cycle 48-bit instructions using an on-chip instruction cache and parallel ALU/multiplier/shifter units. Its dual-ported SRAM enables concurrent core and DMA access without bus contention, supporting simultaneous FFT butterfly operations and background data transfers.
It features two hardware circular buffer address generators (DAG1/DAG2), zero-overhead looping, and bit-reverse addressing-critical for efficient FIR/IIR filter execution and radix-4 FFTs. The 240-lead MQFP_PQ4 package supports thermal management in high-density signal processing modules while maintaining full pin compatibility with other ADSP-21060L variants.
