TI device nomenclature also includes a suffix with the device family name. This suffix indicates the package type (for
example, CYP), the temperature range (for example, blank is the default case temperature range), and the device
speed range, in Megahertz (for example, blank is 1000 MHz [1 GHz]).
For device part numbers and further ordering information for TMS320C6678 in the CYP package type, see the TI
website www.ti.com or contact your TI sales representative.
Figure 2-17 provides a legend for reading the complete device name for any C66x KeyStone device.
