This data manual discusses features and specifications of the TMS320VC5407 and TMS320VC5404 (hereafter referred to as the 5407/5404 unless otherwise specified) digital signal processors (DSPs). The 5407 and 5404 are essentially the same device except for differences in their memory maps.

This section lists the pin assignments and describes the function of each pin. This data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data about the available packaging.

NOTE: This data sheet is designed to be used in conjunction with the?TMS320C5000 DSP Family Functional Overview(literature number?SPRU307).

The 5407/5404 are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses.
