Description

The ADSP-2186 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.The ADSP-2186 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-2186 integrates 40K bytes of on-chip memory configured as 8K words (24-bit) of program RAM and 8K 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-2186 is available in 100-pin LQFP package.
