16-bit, 75 MIPS, 2.5v, 2 serial ports, host port, 192 KB RAM

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.
