Overview
The ADSP-2185LKST-210 is a single-chip, 3.3V microcomputer optimized for digital signal processing (DSP) and other high-speed numeric processing applications. It is part of the ADSP-218xL series from Analog Devices Inc. and is designed to provide high performance and flexibility in various DSP applications.
This microcomputer integrates the ADSP-2100 family base architecture with several advanced features, including two serial ports, a 16-bit internal DMA port, a byte DMA port, and extensive interrupt capabilities. It is particularly suited for battery-operated portable equipment due to its low power dissipation in idle mode and power-down circuitry.
