The is a single-chip Digital Signal Processing Microcomputer is pin-compatible and is differentiated solely by the amount of on-chip SRAM. This feature, combined with ADSP-21xx code compatibility, provides a great deal of flexibility in the design decision. ADSP-2186N series members combine 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. ADSP-2186N series members integrate up to 256K bytes of on-chip memory configured as up to 48K words 24-bit of program RAM and up to 56K words 16-bit of data RAM. Power down circuitry is also provided to meet the low power needs of battery-operated portable equipment.
