Overview
The ADSP-2189NBSTZ-320, produced by Analog Devices Inc., is a member of the ADSP-218xN series of single-chip microcomputers. These microcomputers are optimized for digital signal processing (DSP) applications and offer high performance and low power consumption. The ADSP-218xN series is known for its flexibility, with all members being pin-compatible and differentiated primarily by the amount of on-chip SRAM. This model, specifically, features 32K words of program memory and 48K words of data memory, making it a robust choice for various DSP tasks.
