The ADSP-2185 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.
The ADSP-2185 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, extensive interrupt capabilities and on-chip program and data memory.
The ADSP-2185 integrates 80K bytes of on-chip memory configured as 16K words (24-bit) of program RAM and 16K words (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-2185 is available in 100-pin LQFP package.
In addition, the ADSP-2185 supports new instructions, which include bit manipulations- bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking, for increased flexibility.
The EZ-ICE® serial emulator system provides state-of-the-art emulation for the ADSP-218x family of processors by providing a controlled environment for observing, debugging, and testing activities in a target system. The EZ-ICE connects directly to the target processor through the emulation interface port. Its ease of use, full speed emulation and shielded board will ensure your design process runs smooth.
The debugger available for ADSP-218x EZ-ICE is Analog Devices' VisualDSP++ development environment. All software is sold separately.

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.
