The ADSP-2184L is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.

The ADSP-2184L 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-2184L integrates 20K bytes of on-chip memory configured as 4K words (24-bit) of program RAM and 4K 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-2184L is available in a 100-lead LQFP package.

In addition, the ADSP-2184L supports instructions that include bit manipulations bit set, bit clear, bit toggle, bit test-ALU constants, multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and
global interrupt masking for increased flexibility.
