Product details
Overview
ADSP-21062KS-160 from Analog Devices is a 40 MHz, 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, integrated DMA controller, six link ports, and IEEE JTAG 1149.1 debug interface-designed for real-time audio processing, radar signal conditioning, and industrial motor control systems.
For engineers reviewing the ADSP-21062KS-160 datasheet, ADSP-21062KS-160 pinout, ADSP-21062KS-160 application, or ADSP-21062KS-160 equivalent, key selection considerations include its 40 MIPS instruction rate, 240 MBps link port throughput, 25 ns cycle time, and support for 32-/40-/48-bit word access in multiprocessor configurations.
Technical Context
The ADSP-21062KS-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous dual-data fetch, instruction fetch, and nonintrusive I/O. Its core integrates parallel ALU, multiplier, and shifter units executing single-cycle IEEE 32-bit floating-point or 32-bit fixed-point operations.
It features two hardware data address generators (DAG1/DAG2) supporting modulo and bit-reverse addressing for FFT and filter buffers, plus an on-chip instruction cache enabling three-bus operation-fetching one instruction and two operands per cycle without pipeline stalls.

FAQ
What is the maximum operating frequency of the ADSP-21062KS-160?
The ADSP-21062KS-160 operates at a guaranteed 40 MHz instruction rate with 25 ns cycle time, delivering 40 MIPS and 120 MFLOPS peak performance. This frequency is specified under 5 V ±5% supply and commercial temperature range (0°C to +70°C), and is validated across process, voltage, and temperature corners per Analog Devices' Rev. H datasheet.
Does the ADSP-21062KS-160 support IEEE 754 single-precision floating-point arithmetic?
Yes, the ADSP-21062KS-160 fully supports 32-bit IEEE 754 single-precision floating-point format-including add, multiply, divide, and square root operations-with hardware normalization and rounding. It also supports 40-bit extended-precision format for intermediate accumulation to minimize round-off error in long FIR filters.
How many link ports does the ADSP-21062KS-160 have, and what is their data rate?
The ADSP-21062KS-160 integrates six independent 4-bit link ports, each capable of transferring 8 bits per core cycle at 40 MHz-yielding 240 MBps aggregate throughput. These ports support programmable transmit/receive modes, double-buffered registers, and clock/acknowledge handshaking for reliable inter-DSP communication.
Can the ADSP-21062KS-160 boot from external memory?
Yes, the ADSP-21062KS-160 supports no-boot mode where instruction execution begins directly from external memory. Boot source selection is controlled by BMS, EBOOT, and LBOOT pins; valid sources include 8-bit EPROM, host processor, or link port-enabling flexible system initialization in modular DSP architectures.
Is the ADSP-21062KS-160 pin-compatible with other ADSP-2106x variants?
The ADSP-21062KS-160 shares identical pinout and signal definitions with ADSP-21062KBZ-160 (PBGA) and ADSP-21062LKS-160 (3.3 V version), but is not pin-compatible with ADSP-21060-series parts due to differing SRAM size and internal memory mapping. Always verify power supply voltage and thermal pad connection per package variant.
