Product Overview

The ADSP-2186NBSTZ-320 is a single-chip Digital Signal Processing Microcomputer is pin-compatible and is differentiated solely by the amount of on-chip SRAM. This feature, combined with ADSP-21xx code compatibility, provides a great deal of flexibility in the design decision. ADSP-2186N series members combine 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, extensive interrupt capabilities and on-chip program and data memory. ADSP-2186N series members integrate up to 256K bytes of on-chip memory configured as up to 48K words (24-bit) of program RAM and up to 56K words (16-bit) of data RAM. Power down circuitry is also provided to meet the low power needs of battery-operated portable equipment.

  • 3-bus Architecture allows dual operand fetches in every instruction cycle


Signal Processing


ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
