Analog Devices Inc. ADSP-21062LAB-160

Overview

ADSP-21062LAB-160 from Analog Devices is a 40 MHz, 32-bit floating-point SHARC DSP with 2 Mbit dual-ported on-chip SRAM, IEEE JTAG 1149.1 debug interface, and six 4-bit link ports-designed for real-time audio processing, radar signal conditioning, and medical imaging systems requiring deterministic low-latency computation.

For engineers reviewing the ADSP-21062LAB-160 datasheet, ADSP-21062LAB-160 pinout, ADSP-21062LAB-160 application, or ADSP-21062LAB-160 equivalent, key selection criteria include sustained 80 MFLOPS performance, 25 ns instruction cycle time, dual-data-address-generator support for circular buffers, and glueless multiprocessing capability via distributed bus arbitration.

Technical Context

The ADSP-21062LAB-160 implements the Super Harvard Architecture with four independent buses enabling simultaneous instruction fetch, dual data operand fetch, and nonintrusive I/O-supporting single-cycle execution of multiply + ALU + shifter operations. Its dual DAGs provide hardware modulo and bit-reverse addressing for FFT and filter delay-line management.

It integrates a dedicated I/O processor (IOP), 10-channel DMA controller with background transfer at up to 240 MBps, and a memory-mapped host port compatible with 16-/32-bit microprocessors. The 2 Mbit on-chip SRAM is split into two 1 Mbit dual-ported blocks, each independently accessible by core and DMA in one cycle.

FAQ

What is the maximum sustained floating-point performance of the ADSP-21062LAB-160?

The ADSP-21062LAB-160 delivers 80 MFLOPS sustained performance under real-world workloads such as 1024-point complex FFTs and multi-tap FIR filtering. This value reflects measured throughput with cache hits and dual-bus memory access-not peak theoretical rates. The ADSP-21062LAB-160 achieves this using its dual-ported SRAM and parallel computation units without pipeline stalls.

Does the ADSP-21062LAB-160 support booting from external memory?

Yes, the ADSP-21062LAB-160 supports no-boot mode where instruction execution begins directly from external memory. Boot source selection is controlled by BMS, EBOOT, and LBOOT pins. In this mode, the processor fetches code from the 4-gigaword external address space via its multiplexed 32-bit address and 48-bit data bus-enabling flexible system-level firmware partitioning.

Can the ADSP-21062LAB-160 interface directly with a 32-bit host microprocessor?

Yes, the ADSP-21062LAB-160's host port is fully compatible with 32-bit microprocessors via its memory-mapped external interface. It supports asynchronous transfers at full 40 MHz clock rate using HBR/HBG/REDY handshaking. Host access covers internal SRAM, IOP registers, and DMA setup-requiring no external glue logic for integration into x86 or ARM-based host systems.

What package type and thermal characteristics does the ADSP-21062LAB-160 use?

The ADSP-21062LAB-160 uses a 240-lead thermally enhanced MQFP_PQ4 package with exposed thermal pad. Its junction-to-board thermal resistance is 12°C/W, enabling reliable operation at 2.7 W typical power dissipation without forced air. The package complies with RoHS and supports standard lead-free reflow profiles per JEDEC J-STD-020.

How many link ports does the ADSP-21062LAB-160 have, and what is their data rate?

The ADSP-21062LAB-160 features six independent 4-bit link ports, each capable of 8 bits per core cycle (double-clocked). At 40 MHz, this yields 240 MBps aggregate throughput across all ports. Each port has dedicated double-buffered transmit/receive registers and programmable clock/acknowledge handshaking-optimized for low-latency inter-DSP messaging in radar and beamforming arrays.
