- 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
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.

Evaluation Kits (1)
The ADSP-2189M EZ-KIT Lite provides developers with a cost-effective method for initial evaluation of the powerful ADSP-218x DSP family architecture. The ADSP-2189M EZ-KIT Lite includes a stand-alone ADSP-2189M DSP board and fundamental code generation debug software. With this EZ-KIT Lite, users can learn about DSP hardware and software development and evaluate potential applications of the ADSP-218X M family of DSPs. The ADSP-2189M EZ-KIT Lite provides an evaluation suite of the VisualDSP++ development environment with the C compiler, assembler, and linker. All software tools are limited to use with the EZ-KIT Lite product.
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.
