(1) A type change represents a major functional feature difference in a peripheral module. Within a peripheral type, there may be minor differences between devices that do not affect the

basic functionality of the module. These device-specific differences are listed in the TMS320x28xx, 28xxx DSP Peripheral Reference Guide (literature number SPRU566) and in the

peripheral reference guides.

(2) "Q" refers to Q100 qualification for automotive applications.

(3) See Section 5.1, Device and Development Support Tool Nomenclature for descriptions of device stages. The "TMS" product status denotes a fully qualified production device.
