Looking for STM32H745ZIT6U

Hi, Am looking for STM32H7ZIT6U for my projects could anyone direct me to a reliable source to find them please?Edit: STM32H745ZIT6U​​Thank you

Resolved! Am I getting accurate results from the IBIS models? Is a rise time of 160 ps realistic for a GPIO at 1.8 V?

I'm doing some signal integrity verifications using the STM32H7 IBIS models to determine if I need terminations for connecting my STM32H7 to a HyperRAM memory.I was a bit surprised with the poor signal integrity I was getting, which I assumed was due...
