Overview
The ADSP-2191MKCA-160, produced by Analog Devices Inc., is a 16-bit fixed-point digital signal processor (DSP) designed for high-speed numeric processing and digital signal processing applications. This DSP is software compatible with the ADSP-218x family and features several enhancements that improve performance and C-compiler efficiency. It is available in 144-lead LQFP and 144-ball mini-BGA packages, offering pin compatibility with other models in the series, such as the ADSP-2196 and ADSP-2195, which facilitates easy migration to smaller memory models without hardware redesign.
