Overview
The ADSP-2187NBSTZ-320 is a member of the ADSP-218xN series of digital signal processing (DSP) microcomputers produced by Analog Devices Inc. This series is optimized for digital signal processing applications and offers a high degree of flexibility and integration. The ADSP-2187NBSTZ-320 is designed to be pin-compatible with other members of the series, differing primarily in the amount of on-chip SRAM. It is built on the ADSP-2100 family base architecture, which includes three computational units, data address generators, and a program sequencer, making it highly suitable for complex signal processing tasks.
