Product Summary
The SMJ320C31GFAM50 digital signal processor (DSP) is 32-bit, floating-point processors manufactured in 0.6-μm triple-level-metal CMOS technology. The SMJ320C31GFAM50 is part of the SMJ320C3x generation of DSPs from Texas Instruments. General-purpose applications are greatly enhanced by the large address space, multiprocessor interface, internally and externally generated wait states, one external interface port, two timers, one serial port, and multiple-interrupt structure. The SMJ320C31GFAM50 supports a wide variety of system applications from host processor to dedicated coprocessor. High-level-language support is easily implemented through a register-based architecture, large address space, powerful addressing modes, flexible instruction set, and well-supported floating-point arithmetic.
