STM32H7B0 won't support QSPI SDR (SOP8) memory mapped write, but fyi all following will : STM32L5, STM32L4P5/Q5, STM32U575/585, STM32H5, STM32U59x/U5Ax, STM32U5Fx/U5GxSTM32H7Rx/SxAlex
Hi, which memory PN are you looking for ?Let me just remind that STM32H7B0 supports OPI (APS6408L)... and QSPI DDR (APS12808O-DQ) full spec but have a memory mapped write limitation for QSPI SDR (APS6404L...)ThanksAlex PS: Overview of IoT RAM (QSPI, ...
Hi, Good to hear, I can't comment much about specific for HyperRAM. If competiveness is important, I can just advice to look at APMemory products, APS12808L-3OBM-BA, this is compatible device on your BGA24 PCB footprint.RegardsAlex
Good, for APS6404L-3SQR.you can use the WRAP32 command up to 133MHz and linear burst (with RBX) up to 84MHz.Spec link: http://www.apmemory.com/wp-content/uploads/APM_PSRAM_E3_QSPI_APS6404L-3SQR-v2.6-KGD_PKG.pdfHope all goes wellAlex
