Analog Devices Inc. ADSP-21488KSWZ-3B Digital Signal Processor

The ADSP-21488KSWZ-3B is a high-performance, single-core member of the SHARC® family of digital signal processors (DSPs) developed by Analog Devices Inc. (ADI). It is designed to deliver exceptional processing power with a high degree of functional integration, making it an ideal choice for a wide range of signal processing applications such as audio, video, communications, and industrial control systems.

Equipped with a 32-bit super Harvard architecture, the ADSP-21488KSWZ-3B offers a maximum core performance of 400 MHz, which translates to 2400 MMACS (million multiply-accumulates per second). This processing capability enables the DSP to handle complex algorithms and multiple audio streams with ease. Additionally, the device features a large on-chip SRAM of 5M bits, which provides ample space for data buffering and efficient algorithm processing without the need for external memory, thereby reducing system costs and complexity.

The ADSP-21488KSWZ-3B also boasts a rich set of peripherals and interfaces to support a broad array of applications. These include link ports for direct processor-to-processor communication, serial ports supporting various communication protocols, and a parallel peripheral interface for connecting to external devices. Its SPI and I2C compatible interfaces ensure seamless integration with other components in a system.

ADI's innovative EZ-KIT Lite evaluation system is available for the ADSP-21488KSWZ-3B, providing designers with a comprehensive development environment. This includes an evaluation board, software development tools, and reference examples, which significantly accelerates the design and prototyping process. The CrossCore® Embedded Studio (CCES) software development platform further simplifies application development by providing state-of-the-art debugging and profiling tools.

The ADSP-21488KSWZ-3B is housed in a 100-lead LQFP (Low Profile Quad Flat Package) ensuring a compact footprint for space-constrained applications. Its industrial temperature range of -40°C to +85°C guarantees reliable operation in harsh environments. With its powerful performance, extensive memory, and versatile connectivity options, the ADSP-21488KSWZ-3B is a robust solution for demanding signal processing tasks.
