ADSP-2115BP-40 - 10.24 MHz 24-Bit DSP | Analog Devices
Teilenummer: ADSP-2115BP-40 ✓ AktivADSP-2115BP-40 Übersicht
A digital signal processor is a specialized microprocessor whose internal architecture accelerates operations commonly used in filtering, waveform generation, spectral analysis, modulation, and control. In the broader semiconductor hierarchy, the ADSP-2115 is a DSP microprocessor, an integrated circuit, and a member of the ADSP-2100 family. Unlike a general-purpose processor, it combines a reusable common core with dedicated computation, addressing, sequencing, memory, timer, and serial-interface resources so that many real-time algorithms can be executed with predictable instruction timing.
The ADSP-2115BP-40 combines a 24-bit processor architecture with a 10.24 MHz clock rating. Its computation units and data address generators support efficient implementation of fixed-point signal-processing operations, while the program sequencer organizes instruction flow and the on-chip memory reduces external data-transfer demands. A programmable timer supports periodic tasks, and the family's serial ports allow the processor to exchange data with converters, transceivers, storage devices, or other digital subsystems.
The -40 suffix identifies the 10.24 MHz speed grade within the ADSP-2115 family. This ordering should not be interpreted as a package-pin count; the electrical and mechanical interface remains governed by the PQCC68/LCC-68 device documentation. Designers should preserve the clock, reset, memory, serial-interface, and power requirements associated with this specific ordering when creating a processor board or adapting an existing ADSP-2115 design.
Typical applications include industrial motor and motion control, audio and communications signal processing, data acquisition, industrial measurement, vibration analysis, and embedded instrumentation. In each case, the processor's real-time computation core can execute fixed-point algorithms while its timer and serial interfaces coordinate sampling, data transfer, and deterministic control operations with external circuitry.
A critical design consideration is that software timing and memory assumptions must match the selected ADSP-2115 speed grade. Board designers should also follow the manufacturer pin-description table and recommended decoupling scheme when assigning power and signal routes. This page combines device-level specifications, application guidance, and engineering-oriented interpretation of the manufacturer's ADSP-2115 documentation.

Typische Anwendungen
ADSP-2115BP-40 ist geeignet für 6 Anwendungs: Industrial Motor and Motion Control, Audio Signal Processing, Industrial Data Acquisition, Vibration and Condition Monitoring, Communications Signal Conditioning, Embedded Instrumentation.
Industrial Motor and Motion Control
The ADSP-2115BP-40 fits deterministic motor-control tasks that combine sampled feedback, fixed-point filtering, and periodic control calculations. Its 10.24 MHz clock rating supports a regular computational schedule, while the integrated computation units, data address generators, and program sequencer are designed for high-speed numeric processing. The processor can filter position or current measurements, execute control-law calculations, and update actuator commands at deterministic intervals. The PQCC68/LCC-68 package also provides a straightforward through-hole implementation for industrial controller boards. Designers should derive timing from the selected speed grade and allocate serial or timer resources for encoder, converter, and supervisory interfaces.
Empfohlen
Audio Signal Processing
The ADSP-2115BP-40 is suitable for audio systems that perform sampling-rate conversion, filtering, mixing, dynamic processing, or waveform generation under a predictable timing budget. At 10.24 MHz, its DSP computation units and data address generators can execute fixed-point audio algorithms efficiently, while its on-chip program and data memory help organize working buffers and coefficients. Serial ports can connect the processor to audio converters or additional digital audio equipment, and the programmable timer can organize sample-related service tasks. For production designs, use the manufacturer's serial-interface timing requirements and isolate converter clocking from processor clock routing to prevent sampling errors.
Empfohlen
Industrial Data Acquisition
The ADSP-2115BP-40 can serve as the processing engine in a data-acquisition controller that gathers sensor data, performs filtering and scaling, and forwards results to a host or control network. The common DSP architecture combines computation units, data address generators, and a program sequencer, enabling repeatable execution of acquisition and signal-conditioning algorithms. Its programmable timer supports periodic sampling and processing tasks, while the serial resources can interface with converters, transceivers, or supervisory circuits. The 10.24 MHz clock rating must be included in interrupt-latency and throughput calculations, and the PCB should follow the manufacturer's power and grounding guidance.
Empfohlen
Vibration and Condition Monitoring
The ADSP-2115BP-40 is appropriate for vibration-monitoring equipment that must sample accelerometer signals, perform real-time filtering, extract measurement features, and report events. The dedicated computation units and data address generators support efficient fixed-point filtering and numeric transforms, while the program sequencer organizes repeated acquisition cycles. A programmable timer can establish the analysis cadence, and serial ports can connect the processor to a communications controller or storage interface. Because the -40 ordering defines the 10.24 MHz operating point, firmware timing should be tied to that clock rather than estimated from nominal processor throughput. Signal-conditioning and conversion circuitry must also satisfy the sampling requirements of the selected algorithm.
Empfohlen
Communications Signal Conditioning
The ADSP-2115BP-40 can implement front-end digital signal conditioning for communications equipment, including filtering, interpolation, equalization, or symbol-oriented processing. Its 24-bit DSP architecture and 10.24 MHz clock rating support algorithms that require deterministic repeated execution, while the integrated data address generators simplify access to coefficient and sample buffers. Serial ports provide a path to converters and communications peripherals, and the programmable timer can coordinate frame-related activities. Board implementation should minimize trace length around clock and serial signals, follow the manufacturer's decoupling recommendations, and validate interface timing against the selected converter and protocol requirements.
Empfohlen
Embedded Instrumentation
The ADSP-2115BP-40 fits embedded instrumentation that combines sensor conditioning, real-time analysis, and local control without relying on a general-purpose processor. Its DSP computation resources accelerate numeric routines, the program sequencer supports repeatable algorithm execution, and the timer provides a basis for periodic measurement cycles. The PQCC68/LCC-68 package is practical for through-hole assembly in higher-reliability controller assemblies. Designers should use the exact manufacturer pin description when assigning the 68 leads, confirm memory requirements against available program and data RAM, and calculate worst-case interrupt and loop timing at the 10.24 MHz clock rate.

Designhinweise
Start the PCB layout from the exact Analog Devices PQCC68/LCC-68 pin-description table and preserve the pin-1 orientation. Assign every power and ground lead according to the manufacturer's recommended schematic, then place decoupling components close to their associated supply pins. Treat clock routing as a controlled signal: keep it short, avoid unnecessary stubs, and route it away from noisy switching nodes. Because the package has 68 leads, use the manufacturer pin list to create the footprint and symbol rather than relying on a generic 68-pin library.
Validate clock, reset, memory, and serial-interface timing in hardware using the 10.24 MHz operating point of the -40 speed grade. A stable clock is fundamental because processor execution time, interrupt latency, and timer intervals scale with that frequency. Keep high-speed serial and memory routes as short as practical, provide proper return paths, and avoid routing them beneath noisy analog or power-converter sections. Use scope measurements at the device pins and compare observed timing with the electrical characteristics in the manufacturer datasheet before release.
Do not treat every ADSP-2115 ordering as interchangeable without checking the suffix, clock rating, package, electrical limits, and pin assignments. Software developed for a different speed grade may violate real-time deadlines even if it compiles and runs. Likewise, a processor with a different package can require a new footprint and PCB layout. Establish the exact ADSP-2115BP-40 ordering code in the schematic, bill of materials, and firmware configuration, then repeat timing analysis when any ordering detail changes.
Compliance-Informationen
The device is a general-purpose industrial DSP rather than an automotive-qualified AEC-Q100 product. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the manufacturer or applicable compliance documentation.
