description
The SMJ320C50A digital signal processor (DSP) is a high-performance, 16-bit, fixed-point processor
manufactured in 0.8-
m double-level metal CMOS technology. The SMJ320C50A is the first DSP from TI
designed as a fully static device. Full-static CMOS design contributes to low power consumption while
maintaining high performance, making it ideal for applications such as battery-operated communications
systems, satellite systems, and advanced control algorithms.
