SPRUJG2 December 2024 AM62D-Q1
The AM62D Audio EVM board features a 512Mb OSPI memory device from Cypress part number S28HS512TGABHM010 which is connected to the OSPI0 of the AM62D SoC. The OSPI supports single and double data rates with clock speeds up to 200MBps SDR and 400MBps DDR (200MHz clock speed).
OSPI & QSPI implementation: 0Ω resistors are provided for DATA[7:0], DQS, INT# and CLK signals. External pull up resistors are provided on DATA[7:0] to prevent bus floating. The footprint for the OSPI memory also allows the installation of either a QSPI memory or an OSPI memory. The 0Ω series resistors provided for pins OSPI_DATA[4:7] can be removed if a QSPI Flash is to be mounted.
Reset: The reset for the OSPI flash is connected to a circuit that ANDs the RESETSTATz from the AM62D SoC with the signal GPIO_OSPI_RSTn from the SoC. A pull-up resistor is provided on GPIO_OSPI_RSTn to set the default active state.
Power: Both VCC and VCCQ pins of the OSPI Flash memory is supplied through an on board 1.8V system power. The OSPI I/O group is powered by the VDDSHV1 domain of SoC and is also connected to 1.8V system power.
