ADSP-2189MBST-266 Overview

The ADSP-2189M is notable for its very large on-chip memory (1.5 MBits) and low power features (2.5v).

The ADSP-2189M 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

  • Algebraic assembly language supports C language-style constructs for easy programming
  • 100-lead LQFP package provides for space and power savings (16mm x 16mm)
  • On-chip RAM and 4 DMA ports make reprogramming easy
  • 16-bit DMA port makes bus interfacing easier
  • 5 sleep and powerdown modes maximize battery life.

Features

  • 13 ns instruction cycle time (75 MIPS)
  • 2.5 volt supply with 3.3 volt I/O
  • 32K words of on-chip program RAM
  • 48K words of on-chip data memory RAM
  • 16-bit internal DMA port for high speed access to on-chip memory
  • 8-bit DMA port to byte memory for transparent program and data memory transfers
  •  0.4 mA/MIPS
  • Byte memory interface for storage of data tables and program overlays
  • Programmable memory strobe and separate I/O memory space permits "glueless" system
  • ADSP-2100 Family code and function compatible
  • 100-lead LQFP
  • 144 mini-BGA package
