ADSP-2109

The ADSP-2104 and ADSP-2109 processors are single-chip microcomputersoptimized for digitalsignal processing(DSP) and other high speed numeric processing applications. The ADSP-2104/ADSP-2109 processors are built upon a common core. Each processor combines the core DSP architecture-computation units, data address generators, and program sequencer-with differentiating features such ason-chip program and data memory RAM (ADSP-2109 contains 4K words of program ROM), a programmable timer, and two serial ports.

Fabricated in a high speed, submicron, double-layer metal CMOS process, the ADSP-2104/ADSP-2109 operates at 20 MIPS with a 50 ns instruction cycle time.The ADSP-2104L and ADSP-2109L are 3.3 volt versions which operate at 13.824 MIPS with a 72.3 ns instruction cycle time. Every instruction can execute in a single cycle. Fabrication in CMOS results in low power dissipation.
