Product details
Overview
ADSP-21062LCS-160 from Analog Devices is a 32-bit floating-point SHARC® digital signal processor with 2 Mbit dual-ported on-chip SRAM, 40 MHz instruction rate (25 ns cycle), IEEE 32-bit/40-bit floating-point computation units, and integrated host interface, serial ports, link ports, and DMA controller - deployed in real-time audio processing, radar signal conditioning, and medical imaging systems.
For engineers reviewing the ADSP-21062LCS-160 datasheet, ADSP-21062LCS-160 pinout, ADSP-21062LCS-160 application, or ADSP-21062LCS-160 equivalent, key selection criteria include on-chip memory size (2 Mbit), 3.3 V core voltage, 240-pin MQFP_PQ4 package compatibility, and support for glueless multiprocessing via six link ports and parallel bus arbitration.
Technical Context
The ADSP-21062LCS-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 core and DMA access without contention, while the dedicated I/O processor handles serial, link, and host port transfers independently of the main CPU pipeline.
It features two hardware data address generators (DAG1/DAG2) supporting modulo and bit-reverse addressing for FFTs and filters, plus an on-chip instruction cache that enables single-cycle execution of looped operations like multiply-accumulate and butterfly computations - critical for deterministic real-time DSP workloads.

| RESET | Asynchronous reset input | Active-low signal that initializes processor state, clears registers, and forces boot sequence - must be held low ≥ 100 ns after power stabilization |
| BMS, EBOOT, LBOOT | Boot mode select inputs | Three-pin encoding determines boot source: 8-bit EPROM, host processor, or link port - defines initial program load path at power-up |
| ADDR31–0 / DATA47–0 | External bus address/data multiplex | 32-bit address and 48-bit data shared over external port; supports 4-gigaword unified address space with programmable wait states |
| LxCLK, LxDAT3–0, LxACK (x=0–5) | Link port clock/data/acknowledge | Six independent 4-bit bidirectional links; each transfers 8 bits/cycle (double-clocked), enabling 240 MBps aggregate interprocessor throughput |
| HBR, HBG, REDY | Host bus request/grant/ready | Supports asynchronous 16-/32-bit microprocessor host interface - allows direct read/write of internal memory and IOP registers without CPU intervention |
Key Features
| Feature | Design Value |
|---|---|
| Dual-ported SRAM architecture | Enables simultaneous core processor access and DMA transfer without bus arbitration delay - essential for real-time streaming I/O |
| Hardware circular buffer support | Two DAGs with 32 total circular buffer configurations (16 primary + 16 secondary register sets) - eliminates software overhead in FIR/FFT delay-line management |
| Glueless multiprocessing interface | Distributed on-chip bus arbitration supports up to six ADSP-21062LCS-160 devices + host on shared parallel bus - no external logic required for scalable array systems |
| IEEE JTAG 1149.1 compliance | Full on-chip emulation via TAP controller - enables non-intrusive breakpoint setting, register/memory inspection, and real-time trace without affecting system timing |
| 16-bit floating-point storage format | Single-instruction conversion between 32-bit and 16-bit FP formats - doubles effective on-chip data capacity for coefficient tables and buffers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar floating-point DSP applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADSP-21062LKBZ-160 | Same core, identical 2 Mbit SRAM and 40 MHz speed, but in 225-ball PBGA package - different thermal profile and board layout requirements | Preferred for space-constrained designs where MQFP footprint is prohibitive; requires requalification of thermal management and signal integrity | Select when PCB area is constrained and BGA assembly capability exists; not drop-in compatible due to package mismatch |
| ADSP-21060LCS-160 | Same 3.3 V supply and MQFP_PQ4 package, but 4 Mbit on-chip SRAM and identical 40 MHz speed - higher memory density at same pinout | Used where larger coefficient tables or multi-algorithm partitioning is required without external memory latency penalties | Choose when application demands >2 Mbit on-chip storage; shares same footprint but requires updated memory map configuration |
Compared with ADSP-21062LCS-160, ADSP-21062LKBZ-160 offers identical compute and memory specs in a smaller-area BGA, while ADSP-21060LCS-160 provides double the on-chip SRAM in the same MQFP package - enabling memory-bound algorithms without redesigning the board layout.

FAQ
What is the core voltage requirement for ADSP-21062LCS-160?
The ADSP-21062LCS-160 operates at 3.3 V for both core (VDD) and I/O (VDDIO) supplies, as confirmed in the ADSP-21060L/ADSP-21062L Specifications section (Rev. H, Page 18). This distinguishes it from the 5 V ADSP-21060 variants and mandates compatible 3.3 V power delivery and level-shifting for interfacing peripherals.
Does ADSP-21062LCS-160 support IEEE 754 floating-point arithmetic?
Yes, the ADSP-21062LCS-160 supports IEEE 32-bit single-precision and 40-bit extended-precision floating-point data formats, as stated in the KEY FEATURES-PROCESSOR CORE section (Rev. H, Page 2). Its multiplier, ALU, and shifter units are fully compliant with IEEE 754 standards for arithmetic operations.
How many link ports does ADSP-21062LCS-160 provide, and what is their bandwidth?
The ADSP-21062LCS-160 integrates six independent 4-bit link ports, each capable of transferring 8 bits per core cycle (double-clocked), delivering a total aggregate bandwidth of 240 MBps - confirmed in the MULTIPROCESSING and Link Ports sections (Rev. H, Pages 7–8).
Can ADSP-21062LCS-160 boot from external memory?
Yes, the ADSP-21062LCS-160 supports no-boot mode where instruction execution is sourced directly from external memory, controlled by the BMS, EBOOT, and LBOOT pins (Rev. H, Page 8). This enables flexible system initialization without on-chip boot ROM or EPROM dependency.
Is ADSP-21062LCS-160 pin-compatible with ADSP-21060LCS-160?
No, ADSP-21062LCS-160 and ADSP-21060LCS-160 share the same 240-lead MQFP_PQ4 package and pinout, but differ in on-chip SRAM size (2 Mbit vs. 4 Mbit) and memory mapping - requiring firmware-level adjustments to memory allocation despite mechanical compatibility.
