TMS320C6748: Difference between TMS320C6748EZWTD4 and TMS320C6748EZWTA3

Part Number: TMS320C6748

Hi,

I would like to know the differences between TMS320C6748EZWTD4 and TMS320C6748EZWTA3.

As per datasheet, the difference between the two can be summarized as follows,

Parameter TMS320C6748EZWTD4  TMS320C6748EZWTA3
Operating junction temperature - 40 to +90 °C - 40 to +105 °C
Speed grade 456MHz 375MHz
Nominal CVDD voltage 1.3V 1.2V
Power on hours (hours) 100,000 75,000

Is there any other parameter (in terms of operational and reliability) which differs between these two part numbers?

Regards,

Archana Rao
