ADSP-2184LBSTZ-160 Analog Devices 16bit DSP

ADSP-2184LBSTZ-160 Overview

The ADSP-2184 is a member of the ADSP-218x family. TheADSP-2184 is the lowest cost pin compatible device in the ADSP-218x family. It can be designed into systems the same way as all other ADSP-2100 devices. All previous ADSP-2100 code is code compatible to the ADSP-2184.

The ADSP-2184 combines the ADSP-2100 family base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, and extensive interrupt capabilities.

Benefits
