GENERAL DESCRIPTION
The ADSP-2196 DSP is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.
The ADSP-2196 combines the ADSP-219x family base architecture (three computational units, two data address generators, and a program sequencer) with three serial ports, two SPI-compatible ports, one UART port, a DMA controller, three programmable timers, general-purpose Programmable Flag pins, extensive interrupt capabilities, and on-chip program and data memory spaces.
