I have selected the STM32H743ZIT6 MCU for our project. Our application requires storing 22-byte data for approximately 1.5 lakh entries in RAM. Based on our calculations, we need an external memory of at least 4 MB to 8 MB. The previously considered IS61WV102416BLL-10MLI SRAM does not meet our capacity requirements. Therefore, we require a larger SRAM or PSRAM module that is fully compatible with the STM32H743ZIT6 MCU, supports memory mapping, and can interface via QSPI or asynchronous SRAM. Please provide suitable part numbers and availability details for memory options that meet these specifications.
