ADSP-21992YBC - 150MHz 16-Bit Mixed-Signal DSP | Analog Devices
부품 번호: ADSP-21992YBC ✓ 활성ADSP-21992YBC 개요
A mixed-signal DSP is a semiconductor that processes sampled analog information through digital algorithms while also supervising control functions within the same embedded system. The ADSP-21992 belongs to the ADSP-2199x mixed-signal processor family, where the DSP core handles computationally intensive filtering, modulation, waveform, or control algorithms. Its local RAM permits algorithms and working data to remain close to the processor, supporting deterministic operation in industrial, automotive, communications, and instrumentation systems.
The ADSP-21992 provides 32K words of program RAM and 16K words of data RAM, eliminating the need for external memory in many embedded control designs. Its on-chip CAN controller supports full CAN 2.0B operation with 16 configurable mailboxes and individual acceptance filters. Additional peripherals include a serial port, an SPI-compatible port, a DMA controller, three programmable timers, general-purpose programmable flag pins, and extensive interrupt capabilities.
The fixed-point architecture is appropriate for real-time workloads where predictable execution time, efficient multiply-accumulate operations, and deterministic control behavior are important. At a listed clock frequency of 150 MHz, the processor offers substantially more arithmetic throughput than general-purpose control devices operating from much lower clock rates. Its integrated communication and timing resources reduce the number of external peripherals needed in a compact embedded design.
Typical uses include industrial CAN control nodes, automotive interface modules, motor and motion control, communications equipment, data acquisition, and embedded signal processing. The combination of local program and data memory is especially useful for protocols, control loops, and supervisory logic that must execute reliably without external-memory access delays.
PCB design requires careful attention to the 15 mm by 15 mm 196-lead MBGA layout, power and ground distribution, and high-speed signal routing. Confirm the exact pin assignment, exposed-pad requirements, voltage sequencing, and decoupling values in the manufacturer datasheet before fabrication. Differential or sensitive interfaces should be routed with continuous return paths and short vias to reduce coupling.
This page organizes the processor’s memory, connectivity, package, and peripheral characteristics into an engineering-focused selection reference. It also highlights design constraints and procurement questions that engineers should resolve before committing the ADSP-21992YBC to a new PCB or production release.

Industrial CAN Control Node
The ADSP-21992YBC fits industrial CAN nodes that must combine protocol handling with real-time control. Its on-chip CAN 2.0B controller includes 16 configurable mailboxes and individual acceptance filters, while the 150 MHz fixed-point core can execute control and signal-processing routines between message events. The 32K words of program RAM and 16K words of data RAM allow firmware and working data to remain local. Use the CAN controller with an appropriate external physical-layer transceiver, and validate timing, termination, isolation, and fault behavior for the target network.
추천
Automotive Interface Module
The ADSP-21992YBC can serve as the processing center of an automotive interface module that coordinates CAN traffic and local real-time functions. Its 150 MHz clock, integrated CAN controller, DMA controller, timers, and programmable flags reduce the need for separate communication and timing components. The 32K words of program RAM and 16K words of data RAM are useful for embedded protocol stacks and control logic. Before automotive production use, confirm the exact qualification status, temperature range, transient requirements, and functional-safety obligations for the selected ordering configuration.
추천
Motor and Motion Controller
The ADSP-21992YBC is appropriate for compact motor and motion-control subsystems where fast fixed-point calculations, deterministic timing, and CAN-based command exchange are valuable. Its three programmable timers, DMA controller, serial port, and SPI-compatible port support sensor acquisition, actuator coordination, and supervisory control. The 150 MHz processor provides arithmetic capacity for filters and control algorithms, while 32K words of program RAM and 16K words of data RAM support self-contained firmware. Design the control loop against worst-case interrupt latency and verify the external power stage independently.
추천
Data Acquisition and Signal Conditioning
The ADSP-21992YBC can implement the digital processing side of a mixed-signal acquisition system. Its fixed-point DSP architecture supports filtering, waveform analysis, scaling, and compensation, while DMA transfers data between memory and serial peripherals. Sixteen thousand words of data RAM can hold working samples and intermediate results, and 32K words of program RAM accommodate control and signal-processing routines. Use the SPI-compatible port or serial interface for converters and external sensors, preserve timing accuracy across the sample path, and confirm analog-interface requirements through the system architecture.
추천
Communications Equipment
The ADSP-21992YBC is suitable for embedded communications equipment that performs real-time signal processing alongside supervisory control. Its 150 MHz fixed-point core can execute modem, framing, filtering, and protocol routines, while the serial port, SPI-compatible port, and DMA controller move data efficiently. The integrated CAN 2.0B capability is useful for equipment that participates in an industrial or vehicle network. The 32K-word program RAM and 16K-word data RAM support compact designs, but firmware partitioning and memory usage should be checked against the complete communication stack.
추천
Instrumentation and Test Control
The ADSP-21992YBC can serve as the control and processing element in compact instrumentation where deterministic sampling, local computation, and network management are required. The DSP core handles calibration and digital filtering, the timers establish measurement intervals, and DMA reduces processor involvement during data movement. CAN 2.0B support permits structured communication with a host or distributed instrument. Its on-chip RAM helps keep real-time routines independent of external memory latency. For laboratory or production equipment, validate analog accuracy, clock tolerance, grounding, and isolation separately from the digital subsystem.

선택 가이드
Do not select it as a confirmed drop-in replacement for another SHARC processor. ADSP-21479KBCZ-2A, ADSP-21469KBCZ-4, and ADSP-BF561SBBZ600 can serve as functional comparison points, but their package geometry, memory arrangements, peripherals, voltage requirements, and software environments must be verified. If the board already uses one of those devices, migration may require schematic changes, a new PCB layout, driver modifications, timing analysis, and a fresh qualification effort. Select the ADSP-21992YBC for a new design when its documented CAN integration and on-chip RAM justify the fine-pitch 196-MBGA implementation.

설계 노트
Build the PCB library directly from the 196-ball assignment in the manufacturer datasheet and verify it against the physical BGA drawing. Confirm ball pitches, power and ground balls, analog or special-function balls, and package orientation before releasing fabrication data. A plausible 196-ball count does not guarantee that ball numbers, functions, or power domains match; perform an independent cross-check against the land pattern and assembly drawings.
Partition the 2.50 V core supply and 3.30 V I/O supply according to the manufacturer power architecture, and provide local high-frequency bypass capacitance at each relevant supply ball. Keep sensitive supply distribution compact and connect the ground reference through the package's designated balls. Use the datasheet's recommended capacitor values, voltage ratings, and startup sequence rather than substituting generic bulk and bypass arrangements.
Route clocks, serial interfaces, SPI-compatible signals, and CAN controller interfaces away from high-current switching paths. Provide continuous ground references beneath signal routes, minimize stub branches, and use vias sparingly in sensitive paths. Because the processor and CAN controller share a fine-pitch BGA, plan escape routing and layer transitions before placing decoupling and interface components; this reduces the risk that a nominal 196-ball footprint becomes difficult to assemble or isolate.
Do not treat the ADSP-21992, ADSP-21479KBCZ-2A, ADSP-21469KBCZ-4, or ADSP-BF561SBBZ600 as interchangeable merely because they belong to related processor families. Check boot or configuration behavior, memory sizes and organization, peripheral mapping, voltage levels, clock limits, pin multiplexing, and software model support. The ADSP-21992YBC also requires a CAN physical-layer transceiver; its integrated controller does not directly implement the physical bus interface.
