The 28 pin package cannot be used with the USB operation in industrial temperature.
When using the Encore III Full speed USB Controller with USB Operation in Industrial Temperature, an External Clock should be used.
The option for using external clock oscillator is present in 56 pin package.
If so, doesn't the cypress have the CY7C64215-28PVXI?
How is the CY7C64215-28PVXI used in -40°C ~ 85 °C?
Thanks and Best regards.
As per the datasheet the USB operation cannot be used in Industrial temperature Range in 28 pin package, as we do not have the support for an ECO in 28 pin part.
Industrial temperature operating range for USB requires an external clock oscillator.
Have a nice day.
