Product Introduction

Overview

The ADSP-2187NKSTZ-320, produced by Analog Devices Inc., is a member of the ADSP-218xN series of single-chip microcomputers. These microcomputers are optimized for digital signal processing (DSP) applications and offer high performance and low power consumption. The ADSP-2187NKSTZ-320 is particularly distinguished by its 32K words of program memory and 32K words of data memory, making it a versatile choice for various DSP tasks.

This device is part of a family that includes six different models, all of which are pin-compatible and differ primarily in the amount of on-chip SRAM. This compatibility and the use of the ADSP-21xx code base provide significant flexibility in design decisions.
