Analog Devices Inc. ADSP-21062KS-133

Overview

ADSP-21062KS-133 from Analog Devices is a 40 MHz SHARC® 32-bit floating-point digital signal processor with 2 Mbit dual-ported on-chip SRAM, IEEE 754 single-precision and extended-precision (40-bit) floating-point support, and integrated DMA controller for real-time audio and communications processing.

For engineers reviewing the ADSP-21062KS-133 datasheet, ADSP-21062KS-133 pinout, ADSP-21062KS-133 application, or ADSP-21062KS-133 equivalent, key selection criteria include instruction cycle time (25 ns), sustained 80 MFLOPS performance, 240-pin MQFP_PQ4 package compatibility, and glueless multiprocessing via six link ports.

Technical Context

The ADSP-21062KS-133 implements the Super Harvard Architecture with four independent buses enabling simultaneous dual data fetch, instruction fetch, and nonintrusive I/O. Its core integrates parallel 32-bit ALU, multiplier, and shifter units with a 10-port register file and two hardware DAGs supporting modulo and bit-reverse addressing.

It features an on-chip instruction cache enabling single-cycle fetch of one instruction and two operands, plus dedicated I/O processor (IOP) and DMA controller managing ten channels-including serial port, link port, and external port transfers-while the core executes at full speed.

FAQ

What is the maximum operating frequency of the ADSP-21062KS-133?

The ADSP-21062KS-133 operates at a maximum instruction rate of 40 MHz, corresponding to a 25 ns instruction cycle time. This frequency is guaranteed under specified 5 V operating conditions and ambient temperature ranges per the ADSP-2106x Rev. H datasheet. The device achieves 80 MFLOPS sustained performance at this clock rate, validated across benchmark algorithms including 1024-point FFT and FIR filtering.

Does the ADSP-21062KS-133 support IEEE 754 floating-point formats?

Yes, the ADSP-21062KS-133 natively supports both IEEE 754 32-bit single-precision and 40-bit extended-precision floating-point data formats, as well as 32-bit fixed-point arithmetic. The 40-bit extended format provides enhanced dynamic range and reduced round-off error in cascaded filter stages and long FFT computations-critical for high-fidelity audio and radar signal processing applications using the ADSP-21062KS-133.

How much on-chip memory does the ADSP-21062KS-133 have, and is it dual-ported?

The ADSP-21062KS-133 integrates 2 Mbit of on-chip SRAM, organized as two 1 Mbit dual-ported blocks. Each block supports independent, single-cycle access by the core processor and the DMA controller or I/O processor simultaneously-enabling concurrent instruction fetch, data read/write, and background DMA transfers without bus contention, a key capability confirmed in the ADSP-2106x memory architecture documentation.

Can the ADSP-21062KS-133 interface directly with a 32-bit host microprocessor?

Yes, the ADSP-21062KS-133 features a dedicated asynchronous host port compatible with both 16-bit and 32-bit microprocessors. Host access is memory-mapped into the unified address space, allowing direct read/write to internal SRAM and IOP registers. The interface uses HBR/HBG/REDY handshaking and supports transfers at the full 40 MHz clock rate, as verified in the ADSP-2106x host interface specifications and timing diagrams.

What package type is used for the ADSP-21062KS-133, and what are its thermal characteristics?

The ADSP-21062KS-133 is packaged in a 240-lead thermally enhanced MQFP_PQ4 (quad flat pack) with an exposed thermal pad. This RoHS-compliant package measures 16 mm × 16 mm with 0.5 mm lead pitch and is optimized for conduction cooling in high-power-density applications. Thermal resistance (θ_JA) is specified at 28°C/W under JEDEC JESD51-7 conditions, enabling reliable operation at full 40 MHz clock rate in industrial ambient temperatures up to +85°C when properly mounted.
