The ADSP-2187NBSTZ-320 is a 16-bit fixed-point digital signal processor (DSP) from Analog Devices, designed as a high-performance embedded processing core within the ADSP-2187N series, supplied in a 100-lead LQFP package. This single-cycle instruction execution architecture integrates on-chip program and data memory, a parallel data address generator, and a suite of peripherals—such as serial ports, timers, and an internal DMA controller—enabling deterministic real-time processing without external memory bottlenecks. The device typically operates over an industrial temperature range, making it suitable for environments where electrical performance must be maintained across extended thermal conditions.
Typical applications include precision motor and motion control in industrial automation, embedded audio and speech processing, and low-power digital filtering in defense and aerospace signal chains, where fixed-point arithmetic efficiency and predictable latency are critical. Procurement engineers should evaluate the product’s lifecycle status, as legacy DSP families of this generation carry an elevated risk of obsolescence; sustaining availability for long-life programs often requires validated sourcing from distributors with expertise in end-of-life component management and counterfeit mitigation. The LQFP-100 package offers a balance of board-level routing practicality and reliable surface-mount assembly for high-reliability systems.
