ADSP-21062LCS-160 개요
A DSP (Digital Signal Processor) is a specialized microprocessor whose architecture is optimized for the arithmetic operations that dominate signal processing: multiply-accumulate (MAC), convolution, and finite impulse response (FIR) filtering. Within the semiconductor taxonomy, the SHARC DSP sits under digital signal processors, which are a branch of embedded processors, which in turn are a subset of microprocessors and integrated circuits. The SHARC (Super Harvard ARChitecture) family combines a high-performance floating-point core with integrated system features that would otherwise require external glue logic.
The ADSP-21062 integrates a 4 Mbit SRAM array (2 Mbit configured on the ADSP-21062), a host processor interface, a DMA controller, serial ports, and link ports, forming a complete system-on-a-chip for real-time signal processing. The dual-ported memory allows the core and the I/O processor to access data simultaneously, eliminating the classic single-bus bottleneck. The 32-bit floating-point datapath removes the scaling and overflow management burden that fixed-point DSPs impose on the programmer.
Typical applications include professional audio processing, sonar and radar beamforming, medical imaging, motor control, and telecommunications infrastructure. The link ports enable glueless multiprocessing, allowing arrays of SHARC DSPs to be cascaded for high-channel-count systems.
When designing with this device, note that the ADSP-21062 is a legacy SHARC part and Analog Devices recommends migration to newer SHARC families for new designs; code is not binary-compatible across families, so migration requires source-level changes. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

일반적인 애플리케이션
ADSP-21062LCS-160 적합 용도: 6 애플리케이션s: Professional Audio Processing, Sonar and Radar Beamforming, Medical Imaging Signal Chains, Motor Control and Servo Loops, Telecommunications Infrastructure, Industrial Instrumentation and Data Acquisition.
Professional Audio Processing
The ADSP-21062LCS-160 fits professional audio processing because its 32-bit floating-point core delivers 120 MFLOPS at 40 MHz, enough to run multi-channel equalization, dynamics, and reverb algorithms in real time without the scaling overhead of fixed-point arithmetic. The 2 Mbit dual-ported SRAM holds delay lines and filter state while the DMA controller streams audio samples from the serial ports, so the core is not interrupted by I/O. In a typical topology the DSP sits between an audio ADC and DAC, with the serial ports clocked from the converter master clock. The trade-off is power: the 5 V core and I/O rail dissipate more than a modern 1.2 V SHARC, so thermal design must account for the 240-pin MQFP-EP package's exposed pad.
추천
Sonar and Radar Beamforming
The ADSP-21062LCS-160 suits sonar and radar beamforming because its floating-point MAC unit and 120 MFLOPS throughput handle the delay-and-sum and FFT operations that dominate array processing, while the link ports allow multiple SHARC DSPs to be cascaded without external glue logic for high-channel-count arrays. The 2 Mbit on-chip SRAM stores beamforming coefficients and sample buffers, and the dual-ported memory lets the I/O processor move sensor data in while the core computes. In a typical system the DSP receives digitized array data over the link ports and outputs beam outputs to a host processor through the host interface. The main consideration is that the 5 V supply and 40 MHz clock limit density compared with newer SHARC devices.
추천
Medical Imaging Signal Chains
The ADSP-21062LCS-160 is used in medical imaging signal chains because its 32-bit floating-point datapath preserves the wide dynamic range of ultrasound and CT front ends, and the 120 MFLOPS throughput supports real-time filtering and scan conversion. The 2 Mbit dual-ported SRAM buffers raw channel data while the DMA controller transfers it to the core, and the serial ports interface directly to high-speed ADCs. In a typical ultrasound beamformer the DSP performs channel delay and summation before scan conversion. The design trade-off is that the 5 V supply and 40 MHz clock are modest by modern standards, so channel count per device is limited and multiple DSPs may be required.
추천
Motor Control and Servo Loops
The ADSP-21062LCS-160 supports motor control and servo loops because its single-cycle floating-point MAC executes the Park and Clarke transforms and current-loop PI controllers at the 40 MHz core rate, giving a control-loop update well within the bandwidth of industrial servo drives. The serial ports and link ports connect to encoder interfaces and gate-driver feedback, while the 2 Mbit SRAM holds trajectory tables and filter state. In a typical drive the DSP runs the current loop and passes position commands to a host controller over the host interface. The trade-off is that the 5 V supply and 240-pin package are larger than modern motor-control MCUs, so board area must be budgeted.
추천
Telecommunications Infrastructure
The ADSP-21062LCS-160 fits telecommunications infrastructure because its 120 MFLOPS floating-point throughput and dual-ported 2 Mbit SRAM support the channel filtering, echo cancellation, and modulation functions used in base-station and line-card processing. The link ports enable glueless multiprocessing so several SHARC DSPs can share a channel bank, and the host interface connects to the system controller. In a typical line card the DSP processes multiple voice or data channels in parallel using the DMA controller to move samples between the serial ports and memory. The main consideration is that the 5 V supply and 40 MHz clock are legacy-class, so newer designs favor lower-voltage SHARC devices.
추천
Industrial Instrumentation and Data Acquisition
The ADSP-21062LCS-160 is used in industrial instrumentation and data acquisition because its floating-point core removes the scaling burden from sensor-linearization and FFT algorithms, and the 2 Mbit dual-ported SRAM buffers high-rate acquisition data while the DMA controller streams it from the serial ports. The host processor interface lets the DSP report results to a system controller without interrupting the acquisition loop. In a typical instrument the DSP performs oversampling, digital filtering, and spectral analysis on data from a multi-channel ADC. The trade-off is that the 5 V supply and 240-pin MQFP-EP package require more board area and power than a modern integrated data-acquisition SoC.

설계 노트
The ADSP-21062LCS-160 runs from a single 5 V rail that supplies both the core and the I/O ring, so the regulator must be sized for the combined current, not just the core. Decouple each VDD pin with a 0.1 uF ceramic capacitor placed within a few millimeters of the pin, and add bulk capacitance (10 uF or larger) near the package to absorb the current transients of the 40 MHz core. Estimated: at a typical 5 V core current of several hundred milliamps, the DSP alone can dissipate over 1 W, so verify the regulator's thermal margin before finalizing the power tree.
The 240-pin MQFP-EP package includes an exposed thermal pad that must be soldered to a matching copper land and connected to the ground plane with a via array. Estimated: with a junction-to-ambient thermal resistance on the order of 20-30 C/W for a well-vented MQFP-EP, a 1 W dissipation raises the junction roughly 20-30 C above ambient, which is acceptable at 85C ambient only with adequate copper area. Follow the manufacturer's recommended land pattern and reflow profile for the exposed-pad package.
Route the 40 MHz clock and the external memory bus as controlled-impedance traces and keep them short to minimize reflections and crosstalk. Place series termination resistors close to the DSP on the clock and address/data lines where the datasheet recommends them. Keep the link-port and serial-port traces away from the clock and bus to avoid coupling, and provide a solid ground plane under the entire device to control return currents. Because the part is a legacy 5 V device, level-shift any 3.3 V peripherals before connecting them to the DSP I/O.
Do not assume code portability across SHARC families. Analog Devices states that code compatibility is not possible between processors from different families, so migrating from the ADSP-21062 to a newer SHARC requires source-level changes and re-verification. Also confirm the speed grade suffix (-160 = 40 MHz) and the temperature grade (LCS = industrial -40C to +85C) when ordering, because the same 240-pin footprint is shared by several ADSP-2106x variants with different memory sizes and speed grades.
