Part Number: TMS320VC33
We use TMS320VC33PGEA120 and we're having a few issues with some chips at cold. The chips we have clearly have a A120 marking on the top right but they also have a G4 marking on the bottom right. According to the datasheet, G4 is associated with the commercial temp range parts and is also not shown on the package information on Page 22. What is the significance of the G4 mark?
