• 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

• 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.

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.
