Analog Devices AD73422
The AD73422’s DSP engine 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 AD73422-80 integrates 80K bytes of on-chip memory configured as 16K words (24-bit) of program RAM, and 16K words (16-bit) of data RAM. The AD73422-40 integrates 40K bytes of on-chip memory configured as 8K words (24-bit) of program RAM, and 8K words (16-bit) of data RAM.| Part No. | AD73422 |
