description
This data sheet provides complete design documentation for the second-generation devices of the TMS320
family. This facilitates the selection of the devices best suited for user applications by providing all specifications
and special features for each TMS320 member. This data sheet is divided into four major sections: architecture,
electrical specifications (NMOS and CMOS), timing diagrams, and mechanical data. In each of these sections,
generic information is presented first, followed by specific device information. An index is provided for quick
reference to specific information about a device.
