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.
- 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.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Demonstration programs shipped with this EZ-KIT Lite system include common signal processing algorithms such as convolution and Fibonacci calculations. Programs that demonstrate the use of the hardware features of the ADSP-2189M are provided including interrupts, overlays, timers and the on-board codec.
