Product details
Overview
ADSP-21060LKS-160 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 40 MHz, and 80 MFLOPS sustained performance. It integrates serial ports, link ports, host interface, DMA controller, and JTAG emulation for real-time signal processing in communications infrastructure and audio systems.
For engineers reviewing the ADSP-21060LKS-160 datasheet, ADSP-21060LKS-160 pinout, ADSP-21060LKS-160 application, or ADSP-21060LKS-160 equivalent, key selection criteria include on-chip memory size (4 Mbit), 3.3 V core voltage, 240-lead MQFP_PQ4 package, IEEE 754 32-bit/40-bit floating-point support, and glueless multiprocessing capability via six link ports.
Technical Context
The ADSP-21060LKS-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous dual data fetch, instruction fetch, and nonintrusive I/O. Its dual-ported SRAM allows concurrent access by core and DMA without contention, supporting background transfers at up to 240 MBps over link ports.
It features two hardware circular buffer address generators (DAG1/DAG2), zero-overhead looping, and parallel ALU/multiply/shifter units executing single-cycle IEEE 32-bit floating-point or 32-bit fixed-point operations. The processor supports 16-bit floating-point storage format, doubling effective on-chip data capacity.
