Product Introduction

Overview

The ADSP-2187L, produced by Analog Devices Inc., is a single-chip, 3.3V microcomputer optimized for digital signal processing (DSP) and other high-speed numeric processing applications. This microcomputer is part of the ADSP-218xL series and is designed to provide high performance and flexibility in various DSP applications. It combines the base architecture of the ADSP-2100 family with additional features such as two high-speed serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, and extensive interrupt capabilities. The ADSP-2187L is particularly suited for battery-operated portable equipment due to its five power-down modes and low CMOS standby power dissipation.
