Product Details
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.
